Frequently Asked Questions - Protect A. 1400 VA AEG

What is the typical backup time for the AEG Protect A. 1400 VA?

The backup time depends on load. At half load (490 W), you can expect approximately 15-20 minutes. At full load (980 W), it drops to about 5-8 minutes.

How do I replace the battery on this UPS?

The battery is user-replaceable. Open the front panel, disconnect the battery connectors, remove the old battery, and insert a new one of the same type (typically 12V 9Ah). Refer to the manual for safety precautions.

Why does my UPS beep continuously?

Continuous beeping indicates a low battery condition or an overload. Check the load level and reduce it if above 980 W. If the battery is low, allow it to recharge or replace it if faulty.

Can I connect a laser printer to this UPS?

Laser printers have high inrush current and are not recommended for UPS use. They can cause overload. Connect them to a surge protector instead.

What does the 'Line-Interactive' topology mean?

Line-interactive UPS automatically regulates voltage fluctuations (brownouts, surges) using an automatic voltage regulator (AVR) without switching to battery, prolonging battery life.

How do I connect the USB port for monitoring?

Connect the included USB cable to your computer and the UPS. Install the monitoring software (e.g., PowerPanel or similar) to view battery status, runtime, and perform graceful shutdowns.

What should I do if the UPS doesn't turn on?

First, check the input power cable and ensure the wall outlet is live. If the UPS still doesn't power on, the battery may be completely discharged. Leave it plugged in for at least 6 hours to recharge. If it still fails, contact support.

Is this UPS suitable for sensitive electronics like servers?

Yes, the simulated sine wave output is adequate for most computer equipment and servers. However, for sensitive medical or audio equipment, a pure sine wave UPS is recommended.

How often should I test my UPS?

It is recommended to perform a self-test every 3 months. Press and hold the test button for 2 seconds. The UPS will run on battery for a few seconds and then return to AC.

What is the warranty period for this UPS?

2 System Overview

PROTECT A. is an uninterruptible power supply (UPS) for essential loads such as PCs, workstations relatively small-scale telecommunication equipment and similar devices.

The PROTECT A. series is a compact, interactively operating UPS available with nominal power output ratings 500, 700, 1000 and 1400 VA.

This document describes both types, PROTECT A. 1000 and PROTECT A.1400.

2.1 Brief Overview

The LED display and a pushbutton switch are located on the front of the UPS for straightforward monitoring and operation. The display unit clearly shows the various operating modes using simple pictograms and displays the voltage values and utilisation level of the UPS in numerical format. In addition, the remaining standby time in battery operation is shown in numerical format.

The connections for the mains and the loads are located on the rear of the PROTECT A., as are the communication interfaces and connections for telephone lines/network cables.

Important UPS data is monitored permanently and transferred to the computer via USB or the RS232 interface and using the CompuWatch software.

Features of the PROTECT A.:

♦ VI (line – interactive) protection technology
◆ Automatic voltage regulation against mains voltage deviations (AVR)
◆ Microprocessor control for high reliability
◆ Modern battery management with integrated protection against exhaust. discharge and overloading
◆ User-friendly LC display with optimum legibility
◆ Intelligent monitoring system with USB and RS232 interfaces
◆ Overvoltage protection (RJ11/RJ45) for fax, modem, phone and network
◆ CompuWatch software for shutdown, status messages and measurement values for all major operating systems (incl. Windows, Mac, Linux)
◆ Compact design

2.2 Principle of Operation

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

Under normal operating conditions, i.e. if PROTECT A. is supplied with mains voltage, the battery charger will ensure that the batteries are always completely charged.

During this operating status, the loads connected to PROTECT A. are supplied with voltage via mains filters which provide effective protection against mains voltage peaks and high-frequency faults.

In case of sustained mains undervoltage or overvoltage within defined ranges, the automatic voltage regulator (AVR) further stabilises the load voltage. As a result, voltage fluctuations in the public utility's mains are reduced to a level which is acceptable for the loads. This is performed without recourse to

the internal energy storage, something which in turn has a positive effect on battery availability.

UPS Block diagram PROTECT A.

The static bypass switch is activated in the event of a mains failure. The inverter then takes over the voltage supply of the connected loads, in order to prevent the risk of data loss or damage to the loads. PROTECT A. supplies voltage until the batteries are discharged or your IT system has been shut down and switched off properly.

The standby time mainly depends on the connected loads. If the mains power supply is back to normal values, the UPS will switch back the loads to mains supply. The battery charger will then recharge the batteries.

For safety reasons (as required by German standards, VDE), the mains input in the unit will be disconnected by a two-pole switch in the event of a mains failure. Energy backfeed to the mains and voltage supply to the pins of the mains connector are thus reliably avoided.

Furthermore, additional measures ensure effective protection for the data/network interface.

Information!

Useful and important information for operating the UPS.

3.2 Safety Instructions for PROTECT A.

This chapter contains important instructions for the PROTECT A. UPS. These must be followed during assembly, operation and maintenance of the uninterruptible power supply and the batteries.

The UPS is live, and the voltage can be dangerous. 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 supply, as the UPS has its own internal power supply (battery)!

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

PROTECT A. may only be operated with or connected to a 220 / 230 / 240 VAC mains with protective grounding using a mains connection cable with PE conductor (included in the delivery) that has been tested in accordance with German standards (VDE).

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 A. is exhausted or when the UPS is not working in its normal mode.

Observe the following safety instructions to ensure permanent operational safety of and safe work with the UPS:

♦ 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 UPS 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 and the UPS output!
◆ Ensure that no fluids or foreign bodies can penetrate the UPS!
Do not block the air vents of the unit! Make sure, for example, that children do not insert any objects in the ventilation openings!
♦ Do not connect household appliances such as hairdryers to the UPS!
◆ The mains connection should be near the unit and easily accessible to facilitate disconnecting the AC input or pulling out the plug!
During operation, do not disconnect the mains connection cable from the UPS or from the socket outlet in the building (shockproof socket), otherwise the protective grounding of the UPS and all the loads connected to it will be cancelled.

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!

When replacing the batteries, the following must be observed: Only ever use identical, maintenance-free sealed lead batteries with the same data as the original batteries.

Danger! Explosive!

Never throw batteries into open fire. Never open or damage batteries. (Electrolyte may leak out and damage skin and eyes. It may be toxic!)

Batteries can cause electric shocks and high short-circuit currents.

Therefore, take the following safety precautions when working with batteries:

◆ Take off watches, rings and other metallic objects!
♦ Only use tools with insulated handles!

For personal safety reasons, never switch on the main switch when the mains connector of PROTECT A. is disconnected!

5.2 Installation

Install the UPS unit in a protected location where there is an adequate air supply and where it will be largely free from dust build-up, corrosive vapours and electrically conductive contamination.

Do not operate your UPS where it is exposed to high ambient temperatures or atmospheric humidity. Set up the UPS at least 20 cm away from the monitor in order to avoid interference.

5.3 Charging

The PROTECT A. is supplied with its battery fully charged. Nevertheless, energy may have been lost during transport, so the battery should be fully recharged before it is used for the first time.

Connect the input of the UPS (no. 2 in the figure in chapter 4.3 on page 19) to the mains connection cable provided and plug the mains connector into a suitable shockproof socket. Allow the UPS to charge up for about 6 hours without any load (i.e. without any devices such as computers, monitors, etc. connected to it).

The battery is charged irrespective of the setting of the main switch on the front of the UPS.

5.4 Connecting the Load (e.g. computer)

Connect your loads to the individual UPS backed-up output sockets on the rear of the UPS (chapter 4.3 / no. 1 / pg.19).

Diagram showing two computer setups connected via cable, one with a fan and arrow indicating connection (no text or symbols present)

In this connection, note the special property of the two additional output sockets identified with "SURGE ONLY" (chapter 4.3 / no. 7 / pg. 19).

These are always live irrespective of the other outputs. They are not backed up by the UPS, nor can they be switched off using the main switch of the UPS. It is intended for loads that should be protected against overvoltage but do not necessarily need a continued power supply (emergency power) in case of a mains failure. Limit the power to max. 1000 W.

5.5 RJ11 and RJ45 Data Line Protection (Modem/ Phone/ Fax/ Network)

Connect the incoming phone line/network cable into the "IN" connection on the back of the PROTECT A.

|

Connect the data terminal unit (phone, fax, modem) to the "OUT" socket.

The data line protection supports networks with transmission rates between 10 and 100 Mbit/s.

Data lines are not supplied with the UPS.

5.6 Communication Connection, Connection with USB or Serial Cable

In order to allow unsupervised shutdown of the operating system, connect the RS232 or USB cable as shown in the drawing.

The USB connection is automatically detected.

Diagram showing connection between two computer units via cable, no text or symbols present

The interfaces are mutually exclusive. There is no provision for simultaneous operation of RS232 and USB.

5.7 Operation

Once you have connected the UPS to a suitable mains connection, you can start operation using the UPS main switch.

Switching ON and OFF:

Line drawing of a hand pressing a button on a rectangular device (no text or symbols)

To switch on, press the main switch on the front of the UPS (chapter 4.3 / no. 1 / pg.19). You must be able to feel this engage in its 2nd position.
➢ Press the main switch again to switch off the UPS.

Normally, the UPS operates continuously. The UPS now supplies the output with voltage, this being signalled by activation of the blue backlighting on the LC display (chapter 4.3 / no. 2 / pg. 19).

5.7.1 Normal Operation

During normal operation, i.e. when mains voltage is available, the built-in battery charger keeps the batteries fully charged and the mains voltage monitoring system switches the inverter to standby mode.

The connected loads are powered using the monitored and filtered mains voltage, which is additionally stabilised by the integrated A.V.R. control unit. The “LINE MODE” symbol shows that the unit is active.

5.7.2 Battery Operation / Autonomous Operation

When there is a mains failure or if the input voltage moves outside the tolerance range, the inverter automatically switches over to autonomous mode and supplies the loads with voltage from the batteries. This drains the capacity of the batteries and they are discharged. This status is signalled by the battery symbol flashing as well as an intermittent acoustic signal (chapter 4.3 / no. 2 / pg. 19).

If the UPS does not automatically return to normal operation after a few minutes, close all your work as usual and switch off the loads (e.g. PC) before the batteries are fully discharged. This lengthens the service life of the batteries! Switch OFF the UPS by pressing the main switch.

During the discharge process as the battery capacity consistently drops, the battery symbol flashes, accompanied by an intermittent acoustic signal (once every 10 seconds). The electronics of the UPS switch off the voltage supply of the loads shortly after the battery undervoltage limit is reached (the battery logo above the battery voltage display also flashes; acoustic signal sounds every second).

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

When the mains voltage comes back, the UPS must be switched on again using the main switch (only applies if it was previously switched off manually), in order to recharge the battery and thus store sufficient battery capacity for any possible future mains failures.

The batteries are automatically charged when the mains is present. The battery charging time (to 90% of rated capacity) is about 6 hours after being previously fully discharged.

5.7.3 System Diagnosis / Fault Test

If the monitoring electronics detect an irregularity, the fault indicator is activated which is signalled by the “Fault” pictogram and a digital fault code, possibly accompanied by an acoustic fault signal. This might occur because the battery undervoltage limit has been reached, if the temperature has risen too high, or it might indicate that the internal battery system needs to be renewed.

Faults detected and signalled during diagnosis must be rectified, otherwise there is a risk of load voltage loss if a mains failure occurs!

5.7.4 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 guarantees the availability of the EDP components as well as the data security. The “CompuWatch” shutdown software supports different operating systems, e.g. Windows Linux, Unix, Mac OS X, etc.

Refer to the manual on the CD for details about installing the software on the various operating systems. Other tips and information as well as updates are available from our website at http://www.AEGpartnerNet.com >> PRODUCTS >> Software >> CompuWatch.

6 Displays and Troubleshooting

6.1 LC Display

The blue backlit display is automatically activated after the mains voltage is connected. It operates irrespective of the main switch setting and also when a fault is indicated.

1) The start of operational readiness is signalled on the LC display by all the information content lighting up for about 3 seconds.

2) Mains/normal operation (see also chapter 5.7.1, page 23) is shown by the "LINE MODE" pictogram.

The bottom half of the display shows in the INPUT and OUTPUT voltages of the UPS, the battery (charging) voltage (BATTERY) and the percentage capacity utilisation (LOAD) of the UPS.

3) If the UPS is in voltage-regulating operating mode, the sine part of the "LINE MODE" pictogram flashes every second.

4) If the UPS is in battery mode, the "BATTERY" pictogram lights up and the battery symbol flashes every second.

The remaining standby time is displayed during battery operation according to the load applied. This time is shown in minutes and is indicated by the "MIN" pictogram.

The display shows "0" if the voltage values detected for the input or output are below 40 VAC.

5) The following sample display shows battery charging with the master switch switched off.

The value "0" is automatically displayed for "OUTPUT" if the UPS is in this switched-off condition.

ATTENTION: This does not been the unit has been de-energised in accordance with VDE definitions!

6) Fault indication by the "FAULT" pictogram, associated with a digital fault code in accordance with the table below:

The PROTECT A. consists of state-of-the-art, non-wearing components. We do, however, recommend regular visual checks of the unit to maintain its continuous availability and operational reliability. 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:

The PROTECT A. 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 primarily determined by the site conditions.

Checking the battery

Progressive ageing of the battery system can be detected by regular capacity checks. Every 12 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. Have the battery system renewed if the time drops drastically compared to the previous measurement.

7.1 Battery Replacement

ATTENTION:

A battery can cause an electric shock, and represents a considerable hazard if handled incorrectly.

The following precautions should be taken before the battery is renewed.

◆ Switch off the UPS and disconnect the mains cable from the socket.
◆ Remove any rings, wristwatch and other metallic objects you may be wearing.
◆ If the replacement battery kit is damaged in any way or shows any signs of leaking, please contact your dealer immediately.
◆ Recycle or dispose of the used battery appropriately. Never dispose of batteries by burning. The batteries might explode.

Note:

If you are not qualified to renew the batteries, do not try to open the battery cover. Leave this work to qualified personnel.

The following 3 pictures show the basic steps for changing the battery system. First remove the screw on the underside of the front panel and pull the front panel forwards away from the unit.

Once you have lifted off the actual front panel (which you can put down on top of the unit as shown – never disconnect the flat-ribbon cable) next remove the internal battery cover.

Now slowly pull the two battery blocks out forwards until you can access the cable plug connections. First disconnect the negative terminal then the positive terminal (avoid allowing these connectors to touch one another or the housing) and then remove the battery system from the housing.

Only install batteries of the same type when renewing the battery system!

Installation is the same procedure in reverse. Check the polarity is correct when connecting! (First connect the positive terminal, then the negative terminal – plug in the contacts quickly and firmly!). Dispose of the old battery system in an environmentally friendly manner!

8 Storage and Disposal

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 a higher rate of battery degradation.

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

Connect PROTECT A. to the mains before putting it into storage, in order to make sure that the battery is fully charged.

The charging time should be at least 6 hours.

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.
