2.2 System Description

The UPS is connected between the public utility's mains and the loads to be protected.

The power section of the rectifier converts the mains voltage to DC voltage for supplying the inverter. The circuit technology used (PFC) enables sinusoidal current consumption and therefore operation with little system disturbance. A separate, second rectifier (charging REC set up using switch mode power supply technology) is responsible for charging or trickle-charging the battery connected in the intermediate circuit. The configuration of this charging REC means the harmonic content of the charging current for the battery is almost zero, so the service life of the battery is increased even more. The inverter is responsible for converting the DC voltage into a sinusoidal output voltage. A microprocessor-controlled control system based on pulse-width modulation (PWM) in conjunction with digital signal processor technology and extremely quickly pulsating IGBT power semiconductors of the inverter guarantee that the

voltage system on the protected busbar is of the highest quality and availability.

In the event of mains faults (e.g. current failures), the voltage continues to be supplied from the inverter to the load without any interruption. From this point onwards, the inverter draws its power from the battery instead of the inverter. No switching operations are necessary; this means there is no interruption in the supply to the load.

The automatic electronic bypass serves to increase the security of supply further. It switches the public mains directly through to the load if there is an inverter malfunction. As a result, the automatic bypass represents an extra passive redundancy for the load.

The integrated manual bypass ensures in case of service and/or maintenances a complete power supply of all connected loads. The internal electronic circuit (with exception of the protected manual bypass) can be enabled by the input fuse.

The maximum security of supply for connected loads is achieved by switching up to three PROTECT C. UPS appliances parallel. The n+x technology provides the highest possible availability by a single or double redundancy. On the other hand the power can be raised by using the single redundancy. In case of no redundancy the highest power is reached with the UPS. The relation between available power and active redundancy is explained in the following table:

3.4 Safety Instructions for PROTECT C.

The UPS carries high voltage. The unit may only be opened by trained and qualified personnel. Repairs may only be carried out by qualified customer service staff!

The output may be live, even if the UPS is not connected to the mains, since the UPS has its own internal power supply (battery)!

For health and safety reasons, the unit must be earthed correctly!

PROTECT C. may only be operated with or connected to a 220 V / 230 V / 240 V mains with protective grounding using a CE marked mains connection cable with PE conductor that has been tested in accordance with national standards.

Danger! Risk of burning!

The battery has powerful short circuit currents. Incorrect connection or isolation faults can lead to melting of the plug connections, sparking potential and severe burns!

The unit has a warning signal that sounds when the battery voltage of PROTECT C. is exhausted or when the UPS is not working in its normal mode (chapter 8, page 102).

Observe the following safety instructions to ensure permanent operational safety of and safe work with the UPS and the battery modules (special accessories):

♦ Do not dismantle the UPS!
The UPS does not contain any parts that require regular maintenance. Bear in mind that the warranty will be invalidated if the unit is opened!
◆ Do not install the unit in direct sunshine or in close proximity of heaters!
◆ The unit is designed to be installed inside in heated rooms. Never install the housing in the vicinity of water or in an excessively damp environment!
◆ Condensation may occur if the UPS is brought from a cold environment into the room where it is to be installed. The UPS must be absolutely dry prior to start-up. As a result, leave it to acclimatise for at least two hours.
◆ Never connect the mains input to the UPS output, and vice versa!
◆ Ensure that no fluids or foreign bodies can penetrate the housing!

Do not block the air vents of the unit! Keep children away from the unit and ensure that objects are never inserted through the air vents!
Do not connect household appliances such as hairdryers to the UPS! Also take care when working with motor loads. It is essential to avoid back-feeding the inverter, e.g. if the load is intermittently operated in regenerative mode.

Danger! Electric shocks!

Even after the mains voltage has been disconnected, the components within the UPS remain connected to the battery and can thus cause electric shocks. It is therefore imperative to disconnect the battery circuit before carrying out any maintenance or repair work!

If it is necessary to replace the battery or carry out maintenance work, this must be done by or under the supervision of a specialist familiar with batteries and the necessary safety precautions!

Only authorised persons are allowed in the vicinity of the batteries!

4.2 Transportation to the site

The PROTECT C. provides for easy transportation to the site of installation transport rolls. It is recommended to position the USP such that

◆ the connection tasks can be performed easily;
◆ there is enough space for perfect operation and if necessary for periodical and exceptional maintenance; In this context the cables should be long enough, to be able to move the UPS (for opening the UPS) without switching it off;
◆ the UPS is protected against atmospheric influences;
◆ the humidity and the temperature remain in the specific range;
◆ the fire protection norm are complied.

The battery life time depends strongly of the environmental temperature. The temperature should lie between +15° and 25°C.

Attention!

Only transport the PROTECT C. in upright position. Don't tilt or put on the edges! Prevent dislocation of centre of gravity!

Be sure not to store or use any magnetic storage media near the PROTECT C.

4.3 Point of Installation

Note the following points when setting up the UPS system and its external battery units (special accessories):

◆ The contact surface must be smooth and in level. It must also be sufficiently strong and sturdy to avoid vibration and shock loads.
◆ Make sure the mounting is able to support the weight: This is particularly important in conjunction with external battery units (special accessories).
◆ Set up the units so that adequate air circulation is assured. There must be at least 100 mm clearance at the back for ventilation purposes. Do not block the intake openings on the front and, if present, on the side of the unit. There must be a gap of at least 50 mm here.
◆ Set up external battery units (special accessories) on the side of the UPS system. To ensure the greatest possible mechanical stability, you should not set up the external battery unit(s) above or below the UPS system.
◆ Avoid extreme temperatures! We recommend an ambient temperature of 15 °C to 25 °C in order to maximise the service life of the batteries. Do not expose the units to direct sunlight or operate them close to other heat sources such as radiators.
♦ Protect the units against external effects (in particular moisture and dust). In this regard, please also refer to the instructions in chapter 4.2, page 79 in these operating instructions.

If you transport the unit from a cold room into a warm one, or if the room temperature suddenly drops then condensation may form inside the unit. To avoid any damage due to condensation, leave the unit to acclimatise for 2 hours before you switch it on.

5 Commissioning

Attention

Before any work is started, ensure that the cables are free of tension and no power can be switched on.

To prevent a deformation of the bus-bar and to keep the foot of the terminal free of torsion, it is recommended to hold the cable when removing the terminal screw.

The grounding protection prevents inappropriately high contact tension with reachable metal pieces. The grounding of the PROTECT C. is realised via the grounding screw (/PE). Before starting ensure that the PROTECT C. is grounded according the regulations, e.g. VDE 0100.

Before starting the connection tasks check that:

◆ the values of the mains voltage (input voltage) and frequency complies with the values on the label on the UPS,
◆ the grounding connection complies with the IEC norms or with the regional regulations,
◆ the UPS is connected to the mains via a separate and fused line in a preswitched NS distribution,
◆ the power fuse in the NS distribution has the same or higher value as indicated on the label on the rear of the UPS appliance.

5.1 Protection for the personnel

Before setting up the UPS appliance and the external battery modules (optional accessory) check the following:

♦ Disconnect the unit from the mains.
♦ Protect against reconnection.
◆ Assure for no power.
◆ Ground an short circuit system.
◆ Cover or seals adjacent components still under power.

5.2 Mains connection (general)

To guarantee the correct operation of the UPS and the optional accessories it is necessary to supply the mains line with the respective protection.

5.2.1 Checklist for connectors

The connection and grounding terminals are the same for all the PROTECT C. The cables are connected as follows:

◆ Remove the cover of the terminals.

5.3 One phase mains connector

5.3.1 Preparation for the one phase mains connector

Before starting the connection tasks check that:

◆ the values of the mains voltage (input voltage) and frequency complies with the values on the label on the UPS,
◆ the grounding connection complies with the IEC norms or with the regional regulations,
◆ the UPS is connected to the mains via a separate and fused line in a preswitched NS distribution,
◆ the prefuse or the power fuse in the NS distribution has the same or higher value as indicated on the label on the rear of the UPS appliance,
◆ the connection line from the prefuse to the UPS has to have a minimal diameter as defined in table: „Connection diameter and protection“

The UPS carries high voltage. The unit may only be installed or opened by trained and qualified personnel. Repairs may only be carried out by qualified customer service staff!

5.3.2 Connection of the one phase mains connector

To protect the personnel during installation, ensure that the connection takes place and the following precautions:

◆ No mains power present.
◆ Loads are switched of.
◆ The PROTECT C. is switched of (display completely off).

To activate the PROTECT C. execute the following steps:

◆ Set Manual bypass „Maintenance Switch“ to “Bypass” on the rear of the UPS. Remove the four screws of the cover (Pos. 2, page 83/84).

◆ Set the mains input circuit breaker (Pos. 3, page 83/84) to position “OFF”.

Connect the UPS terminal „PE“ (Ground) with the associated ground terminal in the distribution cabinet.

Connect the mains supply cable with the NS distributor to the „INPUT“ terminal in the UPS:

$$ ⓜ / P E = G r o u n d $$

$$ N = \text { Neutral line } $$

$$ L = \text { Phase } $$

Check the bridge between „JP1“ and „JP2“ (Terminal label „JUMPER“).

Only remove the cable, when using the PROTECT C. in parallel operation with appliances of the same type (see chapter 9).

5.3.3 Preparation for the load connection

Before connecting the loads to the UPS, it is necessary to ensure that the rated power of the label of the UPS is higher or equal to the sum of the power consumption of the loads.

The output of the PROTECT C. should supply the sub distribution in separate power circuits. Check for a selective protection of the circuits.

For the connection between PROTECT C. and the sub distribution cable diameters according to table on page 87 are

recommended. In the sub distribution the following indications are necessary:

♦ Maximal total load
♦ Maximal total load for the separate load power circuits

In the case of one common distributor cabinets (Circuits for mains and UPS power) each has to be labelled separately (Mains or UPS).

5.3.4 Connection of the loads

To protect the personnel during installation, ensure that the connection takes place and the following precautions:

◆ No mains power present.
◆ Loads are switched of.
◆ The PROTECT C. is switched of (display completely off).

To activate the PROTECT C. execute the following steps:

◆ Set manual bypass „Maintenance Switch“ to “Bypass” on the rear of the UPS. Remove the four screws of the cover (Pos. 2, page 83/84).

◆ Set the mains input circuit breaker (Pos. 3, page 83/84) to position “OFF”

Connect the "OUTPUT" of the UPS with the associated terminals.

$$ \begin{array}{l} \text { / PE = Ground } \ \mathrm{N=Neutralline} \ \mathrm{L=Phase} \end{array} $$

5.4 External Battery Expansions

To achieve longer backup time, it is possible to connect multi-battery packs. Connect exclusively the following products together:

PROTECT C. with 1 battery expansion

Technical line drawing of a dual-chamber electronic device with fan, buttons, and wheels (no text or symbols)

Fig.: PROTECT C. 6000 and C. 6000BP

1. Check the correct fit of the UPS and the battery unit (the casings e.g. have to have the same dimension).
2. Now connect both battery connectors using the supplied battery connection cable. When connecting, make sure that you push the plug quickly and firmly in the battery connectors.

Proceed analogue accordingly for a 2. and 3. battery expansion.

5.5 Mechanic blocking of the PROTEC C.

After finishing the connection procedure fix the connection terminal cover again. At the final position fix the cabinets with the breaks against moving away.

6 Electrical Start-Up

Verify that UPS voltage of your country corresponds to your equipment voltage. The default setting is set to 230 V. Output voltage on the UPS system can be adjusted with the software "CompuWatch" in steps of 220 Vac and 240 Vac.

Turn on the PROTECT C. to the mains

1. Ensure, that the connection have been realised according to the installation guide.
2. Ensure, that all loads are switched of.
3. Set manual bypass „Maintenance Switch“ back to “UPS” on the rear of the UPS (Pos. 2, page 83/84). Fix the four screws of the cover.
4. Put the prefuse of the low voltage main distributor (there, where the UPS system is connected on the input side with the mains) back in resp. switch the corresponding line fuse on.
5. Activate the mains input circuit breaker (Pos. 3, page 83/84). If necessary switch it to "ON".

Default setting: The supply of the loads comes via the integrated bypass (Modification of the configuration with the provided Software „CompuWatch“). Don't switch on the loads yet.

1. Now switch on the UPS. To do this, press and hold the UPS ON switch for about 2 seconds.

2. While powering up, the UPS will perform self-diagnosis, the Load/Battery level LEDs will be turned on and then off one after another in ascending order. After synchronising the inverter successfully the LED “Inverter” will go on after a few seconds, with the UPS in normal mode. If the power supply is in order (mains within the range) an additionally the LED “Line” will light up.

i

Please shut down the entire system if you cannot solve any problems which occur. Press the OFF button for about 2 seconds. Disconnect the UPS from the mains by pressing the mains input circuit breaker (Pos 3, page 83/84). Please contact our hotline (page 62).

1. When all displays are lit as described, switch on your loads one after the other. Note the maximum permitted UPS load when doing this.

i

Behaviour when switching off:

The behaviour after switching off the UPS with the mains switch (OFF) can be defined with the Software CompuWatch. The UPS can switch to bypass mode or can be switched of right away.

6.1 Operating

The following operation modes are possible:

Operation with existing mains (6.1.1)

Operation with faulty mains (6.1.2)

Operation with faulty inverter (6.1.3)

Manual bypass (6.1.4)

6.1.1 Normal Operation

Once you have connected the UPS to a suitable mains connection, you can start operation using the UPS main switch. Normally, the UPS operates continuously. The UPS now supplies the output with voltage, this being signalled by the symbols mains (LED Line) and inverter (LED Inverter) symbols which light up permanently.

This is often referred to as “online” mode. It offers the greatest protection, in particular when there are mains fluctuations and mains failures, because the loads are supplied continuously with voltage with no interruptions in this operating mode.

    A["Line"] --> B["Battery"]
    B --> C["Inverter"]
    C --> D["Bypass"]
    D --> A

The LED bargraph (LED chain on the left hand side of the ON / OFF button) show during operation the actual utilization of the UPS (s. chapter 8.1.1, page 102).

6.1.2 Battery Operation / Autonomy Operation

    I["Charger"] --> J["Battery"]
    K["Energy flow with faulty mains"] --> D
    L["Shematic illustration"] --> B

The mains is not within the required tolerance range or has failed. In this case power is supplied to the inverter from the charged battery without interruption. The power supply to the loads is therefore also ensured in the event of a mains failure. This drains the capacity of the battery and it is discharged. This status is signalled by the battery symbol (LED Battery) lighting up, as well as an intermittent acoustic signal every 4 seconds and every second before switching off. This can be suppressed by pressing the “Alarm off” button. With decreasing battery capacity the alarm is activated automatically. Depending on the expansion level, age and condition of the battery and in particular on the load to be supplied, the standby time can vary from a few minutes to several hours.

graph LR
    A["Line"] --> B["Battery"]
    B --> C["Bypass"]
    C --> D["Inverter"]
    D --> E["Output"]

The inverter is switched off if the battery voltage drops below a factory-set minimum voltage value.

Never store the unit in this condition! The discharged battery system should be recharged within a week at the latest.

When the voltage and frequency are within the tolerance range once more, the inverter and the battery charger switch back on automatically. The inverter then continues supplying

the inverter and the battery charger takes over charging the battery.

The LED bargraph (LED chain on the left hand side of the ON / OFF button) show during operation the actual utilization of the UPS (chapter 8.1.1, page 102).

6.1.3 Bypass Operation

graph TD
    A["Mains"] --> B["Manual bypass path"]
    B --> C["REC"]
    C --> D["SBS"]

    I --> J["Load"]
    K["Shematic illustration"] --> L["Mains input circuit breaker"]
    M["Energy flow with faulty rectifier"] --> N["Energy flow with faulty rectifier"]

If the inverter is overloaded or if overtemperature is detected, e.g. also if an inverter defect is detected, voltage is supplied to the load via the bypass that switches on automatically. This is signalled by the bypass symbol.

graph LR
    A["Line"] --> B["Battery"]
    B --> C["Bypass"]
    C --> D["Inverter"]

This function is also referred to as passive redundancy. It protects against total failure of the voltage supply on the protected busbar, however in the operating status that is now attained, mains faults would have a direct effect on the load.

As a result, the electronics continuously attempt to switch back to "online" / normal operating status (e.g. when the overload or overtemperature no longer applies).

The bypass is a mechanical link that switches extremely rapidly. It is located between the load and the mains. The associated synchronisation unit in the bypass ensures that

the frequency and phase of the inverter voltage is synchronised with the mains.

The LED bar graph functions as display for USP utilisation. The signal goes off during this operations status every 2 seconds.

6.1.4 Manual bypass

graph TD
    A["Mains"] --> B["Manual bypass path"]
    B --> C["REC"]
    C --> D["SBS"]
    D --> E["INV"]

    H --> I["Safety bus-bar"]
    I --> J["Load"]
    K["Shematic illustration"] --> L["Mains input circuit breaker"]
    M["Energy flow with active manual bypass"] --> N["MANUAL BYPASS"]

The manual bypass allows maintenance and service personnel to work on the PROTECT C. without switching of the appliance.

If the mains supply fails if the manual bypass is activated, the loads supply fails completely. For this reason, it is important to switch as fast as possible to normal operation mode.

6.1.5 Unit Overload

The load on the UPS should never exceed the specified rated load of the unit. If a unit overload occurs nevertheless (from 105% of the specified unit rated load) the fault LED is turned on accompanied with a signal tone (twice per second). The connected loads continue to be supplied for a certain time depending on the level of the overload. However, the connected load must be reduced without delay.

Non-observance of the "Unit overload" condition may cause the total loss of all UPS functions!

Also avoid short-term unit overloads, which may, for example, occur when connecting a laser printer or laser fax machine.

Do not connect any household appliances or machine tools to the UPS.

Never connect or switch on any additional loads to the UPS if there is a mains failure, i.e. if the UPS is working in emergency power operation!

As a rule, if there has never been an overload during normal operation, there will not be one during battery operation either.

The signalling of the fault LED in combination with a continuous alarm points out a switching of fault. Follow the instructions in chapter 8.2.

7 Interfaces and communication

7.1 Computer interfaces RS232

The UPS offers various interfaces to manage the system and to comfortable readout state information and important parameters. The communication protocol is optimized for operation with the shutdown and UPS management software "CompuWatch" from AEG. To connect the UPS to your computer use the provided RS232 communication cable by attaching them to a free port of your pc.

RS232 interface: The interface is connected via a 9 pole Sub-D connector on the back of the unit (pos. 4 p. 83/84). PINs: 2 = RxD; 3 = TxD; 5 = GND.

7.2 Communication Slot

If the cover on the rear of the UPS is removed (pos. 8 p. 83/84), additional optionally available communication components can be installed there.

AS/400 board: Slot card with status messages, realised via potential-free relay contacts

USB board: Slot card for external USB connection

SNMP board: Slot card for direct connection of the UPS to the Ethernet network with RJ 45 (TCP/IP)

Details can be found in the description enclosed with the particular optional component. Other boards are in preparation.

The usage of the communication slot deactivates the RS232 interface from chapter 7.1.

7.3 Shutdown and UPS management software

The "CompuWatch" software specially developed for these purposes by AEG continuously checks the mains supply and the UPS status.

In conjunction with the "intelligent" UPS, this ensures that the availability of IT components and data security is guaranteed. The "CompuWatch" shutdown software supports different operating systems: Windows 98SE/ME, Windows NT/2000/XP, Windows Vista, Linux, Novell Netware, IBM AIX, HP-UX, SUN Solaris, Mac OS, and others.

Refer to the manual on the CD for details about installing the software on the various operating systems. Updates can be downloaded under www.aegpartnernet.com >> PRODUCTS >> Software >> CompuWatch

If you cannot solve the problem that has occurred, stop the entire procedure, switch off the UPS and disconnect the connector from the socket. Please contact our hotline in this case (see page 62).

Please have the serial number of the unit as well as the purchase date to hand in this case. The hotline will provide you with technical support and can inform you about further procedures once you have described the problem.

9 Parallel operation

9.1 Functionality

PROTECT C. 6000 (S) and C. 10000 (S) was developed for the parallel operation in n+x technology ("n" stands for the number of necessary appliances for load supply, "x" stands for the redundancy level). Up to three appliances of the same type can be connected in parallel to raise the output power and/or to receive a higher availability.

graph TD
    A["NS main distribution UPS mains"] --> B["Three stations"]
    B --> C["Parallel operation field / manual bypass switch plus UPS sub distribution"]
    C --> D["Output"]

The following constellations are possible according to the n+x technology:

1 + 0	Use of 1 unit max. 6 or 1	10 kVA No redundancy
1 + 1	Use of 2 units max. 6 or	10 kVA Single redundancy	( max. configuration level)
1 + 2	Use of 3 units max. 6 or	10 kVA Double redundancy
2 + 0	Use of 2 units max. 12 or	20 kVA No redundancy
2 + 1	Use of 3 units max. 12 or	20 kVA Single redundancy (max. configuration level)
3 + 0	Use of 3 units max. 18 or	30 kVA No redundancy (max. configuration level)

The active redundant parallel operation will switch automatically to the increase power mode if more power is required at the output of the UPS. This implements that the redundancy level decreases or will diminish completely. On the other hand the level of redundancy of the UPS will increase if the power consumption on the output decreases.

The distribution generally is realised in the low voltage main distribution (LVMD) where the external and the following sub distribution for connected load circuits takes place. Such parallel control panels in wall cabinets including an external HU as well as input and output control panel can also be ordered via AEG Power Supply System and their partners.

9.2 Setup / connection of the parallel operation field

The mains connection of each UPS is realised analogue to the description in chapter 5.

For the single phase mains connection for each UPS the same phase has to be used, i.e. all UPS have to use either L1 or L2 or L3 (no mix!). The supply of the multi pole central external manual bypass has to be realised with this phase.

The UPS outlets are connected via separator with the parallel operation bus-bar. At this point the instructions of chapter 5 are to follow.

The following applies for output and input lines of the UPS: The difference in length of the lines with a line length of up to 20 m may not vary more the 20% and with more than 20 m not more than 10%.

The default bridge between “JP1” and “JP2” in the control panel of every UPS has to be removed. The distribution of the output has to be executed according the instructions of chapter 5. Please take care of the exact labelling of the elements to prevent any operation error. The communication between the parallel connected units is realised with the 25 pole parallel operation line that comes with the UPS.

The first step is to remove the parallel port cover (Pos 5, page 83/84) and to connect the UPS with each other with the parallel operation line. With two units use one, with three units use two parallel operation lines (don't build up a ring structure!)

(Communication) parallel operation interconnection

... with 2 units: ... with 3 units:

Four identical industrial refrigeration units connected in series with coiled lines, no visible text or symbols.

After connecting the units with the parallel operation line close the parallel operation cover again. Turn the cover by 180^ such that the notches show to the bottom.

The hardware installation is completed now.

9.3 Operation in parallel compound

The activation process is not complicated and no knowledge is required. Just follow the instructions in chapter 6. Should you have ordered the parallel operation panel from AEG Power Solutions follow the instructions of the separate operation manual. The display of the UPS operates analogue to the description of a single unit in chapter 8.

9.3.1 Activation

1. Check that all connection have been made according to the installation guide.
2. Check that all loads have been switched off.

3. Check that the manual bypass switch "Maintenance Switch" (Pos. 2, page 83/84) on the back of the UPS is in "Bypass" position and that all mains input circuit breaker (Pos. 3, page 83/84) on the back of the UPS are in position "OFF".

4. Check that the central manual bypass is in position „bypass” i.e. that the mains supplies the loads bus-bar.

5. Connect the separator of the output of each UPS, i.e. connect every output of a UPS with the parallel operation bus-bar.
6. Put in the prefuse of the low voltage main distribution field (there, where the UPS systems are connected on the input side with the mains), resp. switch on the corresponding line fuse.

The load supply now takes place via the central external manual bypass. The parallel operation bus-bar is supplied by the integrated bypass of each UPS. Parallel operation bus-bar and load bus-bar are not yet connected at this time!

1. Press the mains input circuit breaker one by one on each UPS (Pos. 3, page 83/84). Bring it to the "ON" position.
2. The manual bypass switch „Maintenance Switch“ (Pos. 2, page 83/84) on the back of each UPS has to be brought into the “UPS” position. Fix on each UPS the cover with the four previously removed screws.

The power supply of the parallel bus-bar now is realised via the integrated electronic bypass equipment of the UPS. Check the operation state on the display of each UPS = bypass (chapter 6.1.3.).

1. Activate the central external manual bypass now: Change from position "bypass" to "UPS operation" i.e. connects the load bus-bar with the UPS parallel operation bus-bar.

This takes place without interruption, if you are using a manual bypass switch with overlapping contacts.

1. Now switch on the inverters of each UPS. To do this, press and hold the UPS ON switch one by one for about 2 seconds.

When being powered on, the UPS will perform self-diagnosis, the Load/Battery level LEDs will be turned on and then off one after another in ascending order. After synchronising all inverters successfully the LED “Inverter” will go on after some seconds on each UPS, with the UPS in parallel normal mode. The loads bus-bar is supplied by the UPS.

Protect the central external manual bypass switch against accidental activation. Never activate the switch when the UPS is in inverter mode.

1. When all displays are lit as described, switch on your loads one after the other. Note the maximum permitted UPS load when doing this. Also keep in mind the spare power, if an active redundancy is required.

9.3.2 Modification in parallel compound

For adding another UPS to the parallel compound or for removing a UPS from the parallel compound, the UPS system has to be brought into the Bypass operation mode.

Load supplied through mains!

(No UPS protection during these steps).

First switch the inverter of all the UPS system one by one off (press the "OFF" switch). All UPS systems are working in the SBS / bypass mode. Check the state on all displays. Activate the integrated bypass (Pos. 2, page 83/84) on the back of the UPS. For this remove the four screws of the cover on the rear.

Bring the mains input circuit breaker of each UPS into the "OFF" position. With the central external manual bypass the

bypass for the loads is done, i.e. activation of the manual bypass operation, suspension of the supply for the load by the UPS bus-bar.

The clearance of the voltage of each UPS is realised in the low voltage distribution. Now the expansion resp. the reduction of the parallel compound can be executed now. Watch out for the bridge between “JP1” and JP2” and the parallel operation line. The activation follows the steps in chapter 9.3.1.

For deactivating the UPS in the parallel compound just press the „OFF“ switch twice behind each other. Like this the UPS-Systems can be removed from the parallel operation bus-bar.

10 Maintenance

The PROTECT C. consists of advanced and resistant components. To guarantee a continuous and high availability it is recommended to check the unit (especially the batteries and the fans) in regular intervals (at least every 6 months).

CAUTION:

Before going through the next step disconnect the PROTECT C. from the mains.

10.1 Charging the Battery

The battery is automatically charged when the mains is present, irrespective of the operating mode. This is signalled by the "charge" symbol lighting up (see also chapter 4.4.2, page 82).

The complete charging time of the battery after a length discharge period depends, above all, on the number of additional external battery units.

Charging time up to 90% of rated capacity

Only with internal UPS battery approx. 7 hours
One additional battery unit	approx. 11 hours
Two additional battery units	approx. 16 hours
Three additional battery units	approx. 24 hours

10.2 Maintenance

The following maintenance work should be performed:

Task	Interval	Described in
Visual check	6 months	Chapter 10.2.1
Battery/fan check	6 months	Chapters 10.2.2 / 10.2.3

10.2.1 Visual Check

When visually checking the unit, check whether:

◆ there is any mechanical damage or foreign bodies can be found in the system,
◆ any conductive dirt or dust has accumulated in the unit,
◆ accumulation of dust affects heat supply and dissipation.

CAUTION:

PROTECT C. must be disconnected from the power supply prior to carrying out the following work.

If large quantities of dust have accumulated, the unit should, as a precaution, be cleaned with dry compressed air, in order to ensure adequate heat dissipation.

The intervals at which visual checks should be performed are largely determined by the site conditions.

10.2.2 Checking the Battery

Progressive ageing of the battery system can be detected by regular capacity checks. Every 6 months, perform measurements to compare the achievable standby times, e.g. by simulating a mains failure. In this case, the load should always have approximately the same capacity demand. Please contact our hotline if the time drops drastically compared to the previous measurement (see page 62).

10.2.3 Fan Checking

Regularly check the fans for dust build-up and noticeably untypical noise development. Clean the intake openings if they are blocked. Contact our hotline if a fan is running unusually loud or irregularly (see page 62).

11 Storage, Dismantling and Disposal

11.1 Storage

Long storage times without charging or discharging the battery at regular intervals may lead to permanent damage of the battery.

If the battery is stored at room temperature (20°C to 30°C) it will automatically discharge at a rate of 3 - 6% per month due to internal reactions. Storing the battery at temperatures above room temperature should be avoided. A high storage temperature also means greater battery self-discharge.

Batteries that are stored at room temperature should be recharged every six months to maintain their full capacity and service life.

Connect PROTECT C. to the mains before putting it into storage, in order to make sure that the battery is fully charged. The charging time should at least match the time specified in chapter 9.2. Charging the Battery on page 112.

11.2 Dismantling

The system is dismantled in reverse order of the installation instructions.

11.3 Disposal

In the interest of environmental protection and recycling, please dispose of the individual system components in accordance with the regulations and legal guidelines when permanently taking the system out of operation. Please consider that infringements to these regulations may result in civil or criminal prosecution.
