Power cables and protective fuses

Always use copper cable types to fit terminals with approximately 1.5 Nm torque for different load currents. The Cu cable sizing is based on multi-core cables laid in conduits/trunkings on the wall or on the floor (installation procedure C), ambient temperature 25°C, PVC insulation, surface temperature up to 70°C. Cables of several UPS can be installed in parallel to each other.

Standards SFS 6000-5-52 (2002) and IEC 60364-5-52 (2001-08) "Electrical installations of buildings" with normal 1.7 x Neutral conductor rating for IT loads are used as a sizing guide. For any other conditions, size the cables according to the local safety regulations regarding installation environment, appropriate voltage and currents of the UPS.

Fuses are sized according to local safety regulations, appropriate input voltage and the rated current of the UPS. Therefore, protect the input and bypass cables with gG (gL) fuses or B-C-D type of circuit breakers against overload and short-circuit.

Contact the manufacturer's authorised agent or the local office for assistance at fuse and cable sizing. Refer to the recommended cable and fuse ratings in the below table.

External Battery Cabinet (EBC) installation procedure

The installation procedure is as follows:

1. The EBC is recommended to place next to the UPS unit.

Note!

Do not place EBC on the UPS unit.

1. The required minimum distance for UPS unit and EBC is ten millimetres, which is also required distance between two EBCs.
2. Turn F1 battery breaker from the UPS unit in OFF position.
3. Check that the circuit breaker F3 of the EBC is in the OFF position. To minimise safety risk disconnect one of the cable (+ or -) from battery string to break a battery circuit. Do not remove the safety wire of the circuit breaker before all the wires are connected and the installation of the whole system is ready. Remove plate A (See figure below.) on the rear side of the EBC to connect cables to EBC's terminal block X6. Bring cables outside from the EBC by removing the cover plate B. Place the plate A back to the original position and use cover plate B as a cable clamp.

Warning!

If an internal battery string is installed and already connected to the terminal block there is a danger of a lethal electric shock. Turn F1 battery breaker from the UPS unit to OFF position and measure the voltage across the terminals to be 0 (zero) before any operations with terminal X3.

1. If the system consists two or more EBC connect first the EBCs parallel as follows:

a) Connect the cables to second EBC in the same way as guided in point four (4) of this installation procedure.

b) Remove the cover plate C of the first EBC and connect cables to terminal block X6. Use the cover plate C as a cable clamp.

1. When all the EBCs are connected parallel, make sure that F1 battery breaker is in OFF position before connecting cables to terminal block X3 of the UPS unit. Otherwise the terminal block X3 is live. To be on the safe side, measure the voltage across the terminals to be 0 (zero).

2. After installation connect disconnected battery cables to strings, check that the removed plates on right positions, remove safety wires from circuit breakers and turn breakers of EBCs and the UPS to ON position.

3. Finally change the Number of 32 pcs. battery strings from User Settings. SETTINGS -> USER SETTINGS -> NUMBER OF BATTERY STRINGS.

Figure 27. Identification of the interface port pins.

LanSafe software

The LanSafe software shuts down computers and whole networks in case of an extended power failure. It provides basic monitoring, data logging, notification and event actions for a single UPS solution. The software is bundled free of charge in Software Suite CD.

The connection procedure for the RS-232 interface port is following:

1. Connect the RS-232 communication cable to the computer.
2. Connect the RS-232 communication cable to the serial interface on the UPS.
3. Run the UPS software installation disk (Software Suite CD) on the computer.

Note!

If communication does not work choose the correct baud rate from the LCD menu. Please refer to the optional software manuals for appropriate bit rate settings.

External control connections

The UPS has an input/output interface for direct communication with your computer system. It is located behind the front bezel of the UPS unit. The cables connected to these terminals should be connected to cable clips.

Input and output terminals have a functional isolation from terminal to terminal. They are connected to the chassis through individual 1 MΩ resistors.

Figure 28. External control cable connections to the UPS.

Note!

Pay attention to proper polarity if one is using a semiconductor switch type. A relay or other mechanical control is a preferred method.

Emergency Power Off (EPO)

This input is used to shut down the UPS from a distance. This feature can be used for emergency power down. There are two modes of operation, normally closed at X52 and normally open at X12. Remote shut down terminal X52 pins 1 and 2 are as factory default linked (X12 is open). When the loop on X52 is opened, the logic circuitry will immediately shut down the UPS output and open the battery breaker (F1).

Note!

EPO does not necessarily disconnect supply to load when unit is on internal or external bypass. Guaranteed disconnection of bypass supply has to be through a separate disconnect switch located in the supplying switchgear cabinet.

In order to have the UPS running again pins 1 and 2 of connector X52 have to be reconnected and the UPS started manually. The pins must be shorted in order to keep the UPS running. Maximum resistance is 10 ohm. The EPO shall not be galvanically connected to any mains connected circuits. Reinforced insulation to the mains is required. See also "Start-up after EPO".

If the use of normally open EPO operation is desired, the loop on X52 has to be retained and the normally open EPO switch connected to X12. Operation is as above.

Relay outputs

The UPS incorporates a programmable relay output with potential free contacts at X57 for remote alarm indications. It is rated for max. 30 VAC 1 A or 60 VDC 0,2 A nominal values. Additional (4) relay outputs can be obtained with the XSlot compatible AS/400 Relay Module (optional). For more information see the section "Using relay outputs"

Warning!

The relay contacts must not be directly connected to mains related circuits. Reinforced insulation to the mains is required.

Programmable signal inputs

The UPS incorporates two programmable inputs (X44, X45). Use of a non-polar (relay) control input is recommended. The pins must be shorted with maximum resistance of 10 ohm in order to activate the specific input.

Note!

Please note the polarity of the inputs as indicated in the external control connections if used with a polarity control.

The default and programmable settings for the signal inputs are

a) Disable Bypass Operation

If active the automatic transfer to the static bypass is prevented.

b) Charger off

If active the batteries charging is disabled. In case of mains power outage the discharge of batteries is supported.

c) Remote ON/OFF

If active the UPS output turns off regardless of mode of operation. Auxiliary power, fan, communications and rectifier/battery charger shall remain functional. Restart initiated immediately when inactive.

d) Request Bypass

If active the UPS transfers to bypass if bypass voltage, frequency and synchronisation are ok.

e) Request Normal

If active the UPS transfers to inverter operation if not prohibited by EPO or alarm condition.

f) Force Bypass

If active the UPS is forced to static bypass operation regardless of the bypass status.

g) External Battery Breaker Status

If active the UPS knows that the batteries are disconnected.

h) Building alarm 1-6

These can be activated separately or at the same time with other building alarms.

i) Not in use (default)

j) Shutdown

If active the UPS will shutdown immediately.

k) Delayed Shutdown

If active the UPS will shutdown after user configurable delay time. Restart initiated immediately when inactive.

1) Normal/Bypass

If active the UPS transfers to bypass if ok. If inactive the UPS transfers to inverter when possible.

m) Output transformer over temperature

If active the UPS output turns off after user configurable delay time.

n) Input transformer over temperature without bypass

If active the UPS will start to operate on battery or shutdown when batteries not available after one minute delay.

o) Input transformer over temperature with bypass

If active the UPS will start to operate on battery or transfer to bypass after one minute delay.

XSlot communication (option)

XSlot modules allow the UPS to communicate in a variety of networking environments and with different types of devices. The UPS incorporates two (2) empty XSlot communication bays.

XSlot #1 XSlot #2

Figure 29. Location of empty XSlot bays.

Table 24. Typical XSlot configurations for UPS communication.

Web/SNMP Module (optional)

The module supports SNMP and HTTP compliant remote monitoring and shutdown for the protected computer systems. It can be connected to a twisted-pair Ethernet network (10/100BaseT) using an RJ45 connector.

The Web/SNMP module has a build-in switching hub that allows three (3) additional network devices to be connected to the network without the requirement of additional network drops. In addition, an Environmental Monitoring Probe can be requested from the UPS manufacturer to obtain humidity, temperature, smoke alarm and security information. It is connected to the communication port of the Web/SNMP module as option.

Table 34. User setting in the LCD menu screen.

Configuring user settings

User settings can be configured via front panel. Select Settings from main menu and then select User Settings.

Changing language

Pressing and holding down the first button on the left for about 3 seconds selects the language menu. This action is possible from any LCD menu screen.

The default firmware has four main languages: English, Spanish, French and German. Other local language packages including Chinese, Greek and Russian can be requested from the local service representative.

Changing charging current

Maximum charging current setting should be checked when needed back-up time needs more than 3 Amps charging current.

Load (kVA)p.f. 0.7	Back-up time Min	current		Load (kVA)p.f. 0.7	Back-up time Min	current
10 1 h 1.8 A 15 1 h	2.5 A
10 3 h 4 A	15 3 h 6.5 A
10 5 h 6.5 A 15 5 h	9 A
10 10 h	13 A	15 10 h		18 A

Table 35. Required battery charge currents.

Select Maximum charging current from User Settings menu. Default setting is 3.0 Amps and it is changeable up to 20 Amps. Minimum step is 0.1 A.

Note!

Maximum charging current is dependent on output load and power rate of the UPS. If the UPS is supporting maximum output load the highest level of Maximum charging current is 3.0 A, which is also the default setting. As a thumb rule, 1 kW decrease in the load provides extra 2.0 A charging capacity. For example, the charging capacity is 5 Amps at 8 kW load, and 7 A at 7 kW load.

Using relay outputs

Relay outputs can be used for remote alarm indications.

Each relay has four standard pre-programmed settings for alarms:

- on bypass, UPS ok, battery low, on battery

One of the standard relay settings is "custom" that can be customised by the user.

The procedure to select customised alarms:

1. Push any key of the control panel to enable the functions on the LCD screen.
2. First select "SETTINGS", then "USER SETTINGS" and finally "RELAY CONFIG" from the LCD menu.
3. Select the relay what is needed to be configured (ALARM-1 is fixed relay output X57).
4. Select "empty" to clear old settings.
5. Select "custom" and activate needed alarms with the button on the right.
6. After the selection press "OK" button
7. Finally test that UPS alarms correctly

Normal start-up

Check the mechanical and electrical installation of the UPS before start-up. Go through the checklist below together with another person.

Check

☐ Read the attached safety manual before you work on the unit.
☐ The unit is fixed according to mechanical installation
☐ The ambient conditions are within specification.
☐ The cooling air will flow freely.
☐ The UPS is grounded properly.
☐ The input and bypass voltages match the UPS nominal voltage.
☐ The input, bypass, battery and output terminal connections are OK.
☐ Appropriate input and bypass fuses and disconnectors are installed.
☐ Appropriate backfeed warning sign for disconnectors are installed.
☐ Appropriate cables sizes are used.
☐ The external control connections inside the UPS are OK.
☐ There are no tools, foreign objects or dust inside the UPS from the installation.
□ Covers are in place.
☐ Optional MBS is placed to UPS position as default.

You are then ready to proceed with the starting up the UPS:

1. Turn the battery and input circuit breakers to ON position.
2. UPS will enter a stand-by mode and starts to charge batteries with a cooling fan operational. Output is without the voltage in the stand-by mode.
3. Push any key of the control panel to enable the functions of the LCD screen
4. Select "TURN UPS ON" from the LCD menu (see: Display Functions)
5. Press and hold ← button for 2 sec. There shall be no sound during the hold.

The UPS shall check its internal functions, synchronise to bypass and start to supply the load. The green LED is blinking if there occurs an active notice. In normal operation the green LED is constantly lit if no new active notice such as 'unsynchronised' or similar notices present.

The output voltage shall be verified from the output measurements screen of the LCD. If there is voltage in the output then UPS is supplying the load.

Battery start-up

UPS will start on battery if mains is not available. Note that the UPS behavior may be slightly different from the normal start-ups.

Start-up after EPO

1. Find out the reason that caused EPO
2. Check that there are no risk to start the UPS again
3. Follow Normal start-up check list and procedure

Shutdown

The procedure to shutdown from LCD is following:

1. Push any key of the control panel to enable the functions of the LCD screen
2. Select "TURN UPS OFF" from the LCD menu (see: Display Functions)
3. Press and hold ↓ button for 5 sec. There shall be an indication sound during the hold.
4. UPS shall do a shutdown routine.
5. Turn the battery and input circuit breakers to OFF position to finalise the shutdown procedure.

Note!

The behaviour is different if UPS is turned off from the programmable input or through communication cards. If battery and input circuit breakers are left ON, UPS will enter a stand-by mode and starts to charge batteries with a cooling fan operational. Output is without the voltage in the stand-by mode.

8. Maintenance

All operations inside the unit must be performed only by a service engineer from the manufacturer or from an agent, authorised by the manufacturer.

The troubleshooting procedure gives simple remedial if a malfunction occurs in the UPS. The operator should start the trouble shooting if there is an active alarm indicated on the LCD screen. Service should be contacted if the active alarm is abnormal and displayed as a service code.

Call service if you are not able to solve the problem.

LCD display Description Action
Overload	The connected load needs more power than the UPS is rated to provide. The inverter or static bypass is supplying the excessive load level.	Shut down the least important load that is connected to the UPS. The UPS should switch back to normal operation once the load level is acceptable.
Battery test failed Your	batteries are detected to be faulty.	Batteries should be replaced and you need to contact the local office or representative of the UPS manufacturer.
Battery low	The UPS is operating in stored energy mode. It will shut down soon due to low battery voltage.	Make controlled shutdown of the protected load immediately to prevent loss of data.
On battery	The UPS is operating in stored energy mode.	Save your data and perform a controlled shutdown of your server load.
Overtemperature High	UPS temperature is detected.	Check that fans are operational and ventilation holes are not blocked. Make sure the ambient temperature is not excessive

Table 36. Typical alarms displayed in the LCD screen of the UPS unit.

Regular service/intervals

The UPS requires very little maintenance if installed in an appropriate environment. In order to ensure maximum availability of the UPS, manufacturer recommends signing a proactive service agreement with a local authorised service provider.

Maintentenance Interval
Batteries change ~ 3-5 years / service
Batteries test ~ 18 months / service
Cooling fan change ~ 5 years / service

Table 37. Routine maintenance intervals recommended by the manufacturer.

Batteries

The condition of the batteries is crucial for operation. The UPS will indicate by audible and visual alarms if the capacity of the battery bank has decreased. The UPS units are provided with the automatic battery test and ABM management function to continuously monitor the condition of the battery bank.

Servicing of batteries should be performed or supervised by personnel knowledgeable about batteries and required precautions. When replacing batteries, replace with the same type and number of batteries.

Note!

Do not dispose of batteries in a fire. The batteries may explode.

Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes. It may be toxic.

CAUTION

RISK OF EXPLOSION IF BATTERY IS REPLACED

BY AN INCORRECTED TYPE.

DISPOSE OF USED BATTERIES ACCORDING

TO THE INSTRUCTIONS

Cooling fan

The cooling fan lifespan of the UPS unit is about 60 000 operating hours. The actual lifespan depends on the environment and ambient temperature.

Fan failure can be predicted by increasing noise from the fan bearings. The fan replacement is recommended once this symptom starts appearing.

Do not use other than manufacturer's specified spare parts.

LED Indicators

The UPS unit has (4) LEDs to indicate the status.

Graphical sign LED	Description Note
	Green UPS status is ok.		Blinking when a new notice message is active.
[2Dz3]	Yellow 1 UPS is in battery mode
	Yellow 2 UPS is in bypass mode
	Red UPS has an active alarm		Blinking when new alarm is not reset and still active.

Table 38. Description of the LED indicators.

Maintenance bypass switch (MBS) operation

The maintenance bypass switch may be as standard or as optional in your system depending on the ordered configuration. The operation of the MBS is allowed for a trained person only who is familiar with the UPS behaviour and functions. The full UPS wiring diagram with a MBS switch is presented in the installation part of the manual.

Note!

The MBS consist of three switches and failure to understand the correct sequence may drop the critical load.

9. Parallel systems

Overview

Parallel UPS configurations are recognised as either redundancy or capacity systems. The redundancy system is used to improve the system reliability with N+1 redundant UPS module. The capacity system for its part provides the maximum output power without focusing to the highest system reliability.

A parameter selection is used to switch between the redundancy and capacity modes. It is important to remember that the mode is affecting to the output power rating and overall system reliability.

UPS modules of the parallel system share equally the load with Hot Sync® technology. The parallel outputs can be combined in a System Parallel Module or cabinet. It is the system component containing the obligatory service switches. Customer's low-voltage distribution panel can also be used instead of the System Parallel Module. In the redundancy system, service switches enable the maintenance or service on an UPS module. In the capacity system, one needs to have a common system bypass switch to do the maintenance or service without safety hazards.

Figure 42. Parallel configurations with UPS modules

Field upgrading can be used to extend existing capacity/redundancy systems with UPS modules. The upgrading must be carried out by service personnel from the manufacturer or from an agent authorised by the manufacturer.

Tie cabinets

The Tie Cabinets (TCs), provided by UPS manufacturer, has input connections up to three parallel UPS modules. It is also possible to use two redundant UPS modules and one bypass connection. This bypass option can be used for service or test purposes.

Note!

It is not allowed to feed the load simultaneously from mains (bypass) and inverter(s) of the UPS unit(s). While turning the switch, where the bypass is connected, ON/OFF, UPS should be on static bypass mode or shut down.

Note!

The maximum load supported by the system is limited to 15 kVA if there are two UPSs and bypass connected to TC (See wiring diagrams below).

Terminals of the TC have two-wire connection (L1 and N) and ground terminals. The upper ground terminal is for a load cable and the lower ground terminal is for UPSs. The wiring shall be done according to the wiring diagrams. The terminals and cable routing is shown in Figure 44.

Table 47. Minimum cable and fuse rating for the different parallel system with installation procedure C * (system bypass not allowed)

Note!

Protection fuses need to be used for load cabling if manufacturers Tie Cabinet (or similar) not used.

Required parallel system wiring length should be in accordance with the following rule, as referenced to the diagram below to ensure approximately equal current sharing when in static bypass mode (see Figure below:

Total length of 1A + 1B = Total length of 2A + 2B

= Total length of 3A + 3B
= Total length of 4A + 4B

This rule has a tolerance of approximately ± 10% for the combined input and output wire lengths. If installing only two UPS modules, this requirement is no longer required as each UPS is capable of supporting the full bypass requirement. However, this would preclude future expansion.

Figure 50. Communication cabling wiring

Note!

XSlot Hot Sync card has built-in termination resistor enabled by a jumper J7. The default jumper setting without termination resistor is J7: Pin 2-3. The first and the last UPS modules should have the termination resistor enabled by connecting Pins 1 and 2 with the jumper J7.

Parallel operations

Start-up

Note!

Before start-up make sure that UPS installations have been carried out correctly and ground connections of both UPS units and parallel module have been connected. Check also that the XSlot Hot Sync cards are installed correctly and the communication line between UPSs is connected according to figure Communication cabling wiring.

When installation is completed correctly the start procedure can be started.

Note!

If some settings are changed from User settings the same changes need to be done separately to all of the UPSs in the system.

Carry out the following procedure to each UPS you want to have in system

1. Turn the battery and input circuit breakers to ON position.

2. UPS will enter a stand-by mode and starts to charge batteries with a cooling fan operational. Output is without the voltage in the stand-by mode.

3. Push any key of the control panel to enable the functions of the LCD screen

4. Select unit number in parallel system: Unit #1, Unit #2, Unit #3 or Unit #4. Select: SETTINGS -> USER SETTINGS -> PARALLEL OPERATION SETTINGS -> PARALLEL UNIT NUMBER

5. Select minimum units to support load: 0-4. Select: SETTINGS -> USER SETTINGS -> PARALLEL OPERATION SETTINGS -> MINIMUM UNITS TO SUPPORT LOAD

Do the following item (item 6) only for one UPS, which belongs to the system

1. Return to main menu and select TURN SYSTEM ON

All the UPSs shall check their internal functions, synchronize to bypass and start to supply the load.

Note!

After the first start the load sharing of the system needs to be calibrated. Before starting the calibration the system needs to support some load.

1. Select: SETTINGS -> USER SETTINGS -> PARALLEL OPERATION SETTINGS -> START AUTO CALIBRATION

Shutdown

While system is running and UPSs are supporting load, there are two different ways to perform a shutdown. The user can select either to shutdown the whole system or only one UPS.

1. Select TURN SYSTEM OFF from the main menu => All the UPSs in the system will go to stand-by mode.
2. Select TURN UPS OFF => Only the selected UPS will go to stand-by mode.

When UPS is in stand-by mode it still charges its batteries and uses cooling fans. Stand-by mode possibles a fast restart. If some UPS or all the UPSs in the system need to be shutdown completely, proceed to item 3.

1. Select TURN UPS OFF and press and hold ← button for 5 seconds. There shall be an indication sound during the hold.

2. UPS shall do a shutdown routine.

3. Turn the battery and input circuit breakers to off position to finalise the shutdown procedure.

10 Recycling the used UPS or batteries

Before scrapping UPS or its battery cabinet, the battery bank must be removed. Local requirements must be followed in battery recycling or discard. The removal of batteries is allowed only by authorised service personnel due to high energy and voltage.

Do not discard waste electrical or electronic equipment in the trash.

For proper disposal, contact your local collecting/recycling/reuse or hazardous waste center and follow the local legislation.

These symbols indicate on a product:
