1.1 Introduction

The GE (General Electric) Digital Energy NetPro UPS, a truly on-line uninterruptible power supply,protects your equipment from all forms of power interference, including complete power failures.

1.2 Safety Rules

! CAUTION: RISK OF ELECTRICAL SHOCK. The UPS contains batteries. The applianceoutlets may be electrically live, even when the UPS is disconnected from the mains.

! The UPS contains potentially hazardous voltages. Do not open the UPS, there are no userserviceable parts inside.

! All maintenance and service work, including replacement of the batteries, should beperformed by qualified service personnel.

1.3 Transport / Storage

! No liability can be accepted for any transport damage when the equipment is shipped in non-original packaging.

! Store the UPS in a dry location with the batteries in a fully charged state. Storage temperaturemust be within -20 +45 "C. If the unit is stored for a period exceeding 3 months, optimal batterylifetime is obtained if the storage temperature does not exceed 25°C.

! If the unit is stored for an extended period of time, the batteries must be recharged periodically.Connect the unit to a wall outlet and recharge the batteries for 24 hours:- if the storage temperature is within -20 and +30°C: every 3 months,- if the storage temperature is within -20 and +45°C: every month.

The shipping box contains a NetPro UPS, two IEC male-female power cords, a data cable, a CD ROMand this manual. Inspect the UPS for damage after unpacking. If any damage is present pleaseimmediately notify the carrier and place of purchase.

IMPORTANT:Before making any connection and switching on the NetPro UPS, please check the followingconditions:

! your mains supply is 220 - 240 Volts and 50 (if the mains frequency is 60Hz, the output frequencyof the UPS can be changed, see section 3.4), and

! the total power demand of the connected equipment does not exceed the rated output power ofthe NetPro UPS (indicated on the rating label) (6, fig. 1).

WARNINGConnecting the UPS output to neutral or ground will result in a malfunctioning UPS, unless yourunit is a "NetPro+", i.e. equipped with an isolation transformer.

2.1 Installation Rules

! The UPS is intended to be used in normal domestic and office situations.! Protect the UPS, according to the wiring rules, with a 16A (NP 2000/3000VA) or 25A

(NP 4000VA) D-type fuse.! The UPS must be powered from a single phase wall outlet equipped with protective earth. Do not

use extension cords.! Avoid locations that are excessively humid, near water, near heat sources or in direct sunlight.! The ambient temperature should not exceed 40"C. Optimal battery lifetime is obtained if the

ambient temperature does not exceed 30"C.! It is important that ventilation air can move freely around and through the unit. Do not block the air

vents.! Do not plug appliances such as electric heaters, toasters and vacuum cleaners into the UPS.! Be careful when connecting laser printers: be sure that the demanded power does not exceed the

capacity of the UPS.! The sum of the leakage currents of the UPS and the connected loads should not exceed 3.5mA.

GE Digital Energy g2.2 Installation Procedure

1 Switch off your computer, and unplug it from thesocket-outlet.

2 NetPro 2000: Disconnect the power cord from thecomputer (rating 250Vac/10A) and connect this cordto the mains input socket (2, fig. 1) of the UPS. Seefig. 2.NetPro 3000/4000 models are equipped with a fixedpower cord (11, fig. 1).

3 Using the output cords provided, connect thecomputer equipment to the appliance outlets (4, fig. 1)of the unit. Spread the loads over the appliance outletsas equally as possible. If you use a distribution box toconnect more than one appliance per outlet, pleasenote that the maximum AC-current rating of eachappliance outlet is 10A. See fig. 3.Output 4a is programmable: see 3.4.3.

If your UPS is a 4000VA model please proceed withstep 5.

NetPro 2000/3000 only.4 Battery extension pack(s) can be installed to

increase the battery runtime. Connect the DCconnector of the battery pack (9, fig. 1/4) to the DCsocket of the UPS (7, fig. 1/4). You will hear a clickwhen the cable is properly installed. Block the DCconnector: install the small locking plate (9a, fig. 4)that came with the battery pack, and fasten it withthe screw provided. Using the DC connector of thebattery pack (10, fig. 1) you can install a second,third, etc. pack. See 5.1 for more information.

5 Make sure the on/off switch (12, fig. 1) at the rear of the UPS is off, i.e. in position ‘0’, and connectthe mains cord of the UPS to a working, AC wall socket outlet equipped with a protective earthconnection. The fans start rotating: mains power is available and the batteries are charging.

6 For best results, allow the UPS to recharge the batteries during a period of approx. 12 hours. It isacceptable to use the UPS without first charging the battery, but the runtime may be reduced.

7 For advanced communication possibilities, the RS232 interface port (3, fig. 1) can be connectedto a computer system and/or optional interface cards (5, fig. 1) can be added. See chapter 4.

3.2 Start-up

3.2.1 Start-up, mains available1 As soon as the power cord is plugged into a working wall outlet, the battery charger is active: the

batteries are being charged.2 Switch on the UPS with the 'on/off' switch (12, fig. 1) at the rear of the unit; the green LED

'operation' will illuminate.3 The equipment connected to the UPS can now be switched on. (The 'soft start' capability of the

UPS allows that the on/off switch of the UPS can be used as a 'master switch': all equipmentprotected by the UPS can be switched on by simply switching on the UPS. The simultaneouslyoccuring inrush currents of the loads do not immediately cause bypass operation.)

3.2.2 Start-up, mains not available (battery start)If the mains input is absent (power cord not connected, or mains failure):

GE Digital Energy g3.4 Use: Screen MenusOperation of the NetPro UPS is done via the push-buttons and the LCD screen on the front panel. Inaddition 4 LEDs inform the user about operating conditions.

Furthermore some functions of the UPS can be programmed via the RS232 communication port. Formore information see section 3.6 and chapter 4.

The messages displayed on the LCD screen can be divided into three menus:• Default menu• Status and alarm menu• Setup menu

If the UPS operates under normal conditions, the LCD shows the standard menu. The message showndepends on the operating mode of the UPS. From any menu, the LCD screen will always return to thestandard menu after a push-button inactivity time-out of 20 seconds.If the operating conditions change, e.g. by a mains failure or rise of temperature, a ! mark will appear inthe right lower corner of the display. With key #### (18) you can enter the status and alarm screens.The setup menu allows you to program the UPS. To enter the menu press #### (18) until the menu isreached. You can scroll through the individual setup screens with $$$$ (20) and #### (18).

3.4.1 Default menu

Under normal operating conditions (see 3.3.1), the LCD shows a default screen (the mentioned valuesare examples):

GE Digital Energy g3.4.2 Status messages and alarm messages

The NetPro UPS alerts the user with a blinking ! signal on the LCD that the status has changed or that analarm situation occurs. The accompanying screen messages appear after the push-buttons $$$$ or #### havebeen pressed. The blinking ! signal will disappear from the display (see also 3.4.1).

3 kinds of messages can be displayed on the LCD:

- status indications indicate the UPS operating mode(3.4.2.1)

- low priority alarms indicate abnormal operating situations; the screen message is accompa- (3.4.2.2) nied by a 1x per 8 secs. sounding buzzer. The buzzer is resettable with the

OK button (19), but only after the default screen is displayed again.In case of 'weak mains' the yellow LED (16) on the front panel illuminatesand the buzzer remains silent.

- high priority alarms indicate situations in which the connected load is at risk as a proper output (3.4.2.3) voltage of the UPS is no longer guaranteed; immediate action should be

taken. The screen message is accompanied by a red LED 'alarm' and a 1xper second sounding buzzer. The buzzer is resettable with the OK button(19).

NetPro 3000/4000 only:One of the applicance outlets (4a, fig. 1) is programmable. Three settings are possible:

! ON! OFF! AUTO

When the UPS is started the outlet is always switched ON, but it can be switched off either manually orautomatically.With the default setting 'ON', the outlet functions similar to the other appliance outlets: it delivers outputpower as long as the output converter does. When 'OFF' is selected, the outlet switches off. When theoption 'AUTO' is selected, the system asks for the 'Off autonomy time': the remaining runtime (in minutes)at which, during a mains failure, the programmable output is automatically switched off until the mainsreturns. This way less critical equipment (e.g. screens, printer) can be switched off automatically in orderto lengthen the remaining runtime.Figure 6 shows an example. The total predicted runtime is 15 minutes, and the 'off autonomy time' hasbeen set on 5 minutes: the outlet switches off 5 minutes before the predicted end of autonomy.

As the load decreases when the outlet switchesoff, the actual remaining autonomy at the 'outletoff' moment (which was predicted at presentload) will be longer than the programmed 5-minute period.In configurations with small loads and largebattery capacities, i.e. very long runtimes, thestep size with which the runtime is counteddown can be longer than the programmed 'offautonomy time' (see section 3.5). In this casethe programmable outlet will be switched offwhen the remaining runtime is one step fromzero.

Example: suppose the runtime is counted down with 10 minute steps, and the 'off autonomy time' is setas mentioned above. Despite of the 5-minute setting, the outlet will be switched off 10 minutes (= onestep) before end of autonomy.If the step size does not exceed the 'off autonomy time', the programmable outlet will be switched off atthe programmed moment although the accuracies may not match. Example: 'off autonomy time' set at 14minutes while the step size is 10 minutes, the outlet will indeed be switched off 14 minutes before the endof the autonomy.If the option 'AUTO' is selected the programmable outlet can still be switched off manually using the frontpanel keys.Each time the mains returns, the programmable outlet will always be switched on. Therefore do not usethis outlet to switch off equipment that should permanently remain off.

The frequency tracking rate is the maximum rate at which the UPS adjusts its output frequency tofluctuations of the input frequency. If the UPS is not connected to a generator set the default setting maybe too high. Note that a change of the frequency tracking rate is coupled with a change of the trackingrange (see chapter 8, bypass).

The runtime, below which the UPS is inhibited to start up, can be set here. The UPS will first recharge itsbatteries and start up as soon as the 'start up autonomy' is available. The setting can be bypassed (seealso 3.2.3). Calculation of the 'start up autonomy' is based on the assumption that the UPS supplies 100%load.

etting ‘ON’ means that the function is activated: the UPS will switch off during a mains failure when thead is < 5% of the maximum load. Be careful with very small loads: e.g. a fax machine in stand-by modeould be recognised by the UPS as a no-load situation.

the NetPro is supplied by a generator set, and the generator's frequency is often out of the UPS's inputlerances, frequently occurring 'bypass error' alarms (see 3.4.2.2) will be the result. During these alarmsypass operation is inhibited. To avoid this situation the bypass function can be disabled: the UPSnctions as a UPS without automatic bypass switch.

he output frequency can be set to 50/60 Hz.OTE: The unit can be used as a frequency converter: the input frequency range is 45-66Hz, the outputequency is selectable 50/60Hz. If the unit is used as a frequency converter, the bypass function is nonger available. As a result an audible alarm will be generated continuously (see 3.4.2.2 ‘Bypass error’).o avoid this, we advise to disable the bypass (see above).

WARNING:Changing of the output frequency can cause severe damage of equipment connected tothe appliance outlets of the UPS: Be sure that the new frequency is suitable for theconnected equipment!

GE Digital Energy g3.5 Runtime: calculation and indicationThe available runtime is displayed in the default screen, and is counted down during battery operationuntil either the mains returns or the batteries are empty.

Normally, i.e. if the runtime is less than 100 minutes, the runtime is calculated in minutes, and the stepsize of the changes is one minute. In case of small loads and/or battery extension packs the availableruntime can be substantially longer. The accuracy of the runtime calculations however is limited: approx1% of the initial runtime.For this reason the measuring unit and step size will change at longer runtimes: if for example the runtimeis between 200 and 500 minutes the step size is 5 minutes; if the runtime is > 5000 minutes the runtime iscalculated in hours and the step size is 2 hrs. The following table gives an overview:

Runtime Rt, in minutes Unit Step size

Rt < 100 minutes 1 minute

100 ≤ Rt < 200 minutes 2 minutes




2000 ≤ Rt < 5000 hours 1 hr

Rt ≥ 5000 hours 2 hrs

Please note that unit and step size do not change during countdown: the initial units and step sizesremain unaltered, until eventually the batteries are empty.If during battery operation the available runtime becomes less than the step size it will be shown as '< S',where S is the step size. If for example the initial autonomy was 1200 minutes, i.e. between 1000 and2000, the countdown occurs with steps of 20 minutes each, and during the last 20 minutes before thebatteries are empty the runtime will be displayed as '< 20 min'.

3.6 Other Features

3.6.1 Shutdown

Using communication capabilities, the computer can direct the UPS to turn itself off following controlledshutdown of the system. Subsequently the UPS will remain off for at least 30 seconds. LED 'operation' willgo out. The unit will start up again as soon as the mains returns (and, if activated, the start-up runitme isavailable).

3.6.2 Programmed shutdown

The UPS monitoring software allows you to program a 'sleep period' of the UPS by sending twocommands to the UPS:

- shut down after # minutes, and subsequently:- shut down during # hours.

The first command indicates the period of time after which the UPS should 'fall asleep', the secondindicates the duration of the sleep period. After the first command LED 'prog shutdown' starts blinking andthe standard screen shows the time until sleep (see 3.4.1). In the 'sleep'-mode LED 'operation' is off, LED'progr. shutdown' is on, and the LCD shows the remaining sleep time:

Dsdpa

Tc

#65>'J7A6='O@N>_SS_``_((


uring the 'sleep period' the UPS is not completely switched off as it has to keep track of the remainingleep time. However, if a mains failure occurs during the sleep period and the battery capacity eventuallyrops below 80% of the normal capacity, the UPS will automatically switch off in order to save batteryower. When the mains returns the UPS will start up automatically (as soon as the start-up runtime isvailable, if this feature is activated). The programmed sleep time however is lost.

he programmed shutdown in progress can be cancelled: press the OK button during 10 seconds toancel shutdown and switch the UPS on.

.6.4 Quick battery test

utomatic test: The NetPro UPS conducts periodic automatic battery tests to ensure that the batteriesnd the wiring are healthy and able to support power failures. The tests do not cause any interruption in

he function of the unit and are conducted at the following times:· 5 hours after manual switch-on· 5 hours after return of mains following any power failure, and· 30 days from the last battery test.

anual test: A manual quick battery test can be activated- either through an interface kit, via the RS232 Interface Port (please refer to the manual of your

interface package), or- via the front panel with the push-buttons ####, OK and $$$$. The procedure is as follows:

rom a default screen, press push-button $$$$ (20) until the display shows

!@AA>BC'A>EA

If no test has been performed since switch-on, the second line of this screen shows 'NO RESULT' untilush-button 'OK' is pressed).ush-button OK (19) confirms the selection, and the screen shows:

!@AA>BC'A>EA!JEC'A>EA67I


he test status (indicated by the second line) can be:

USY TESTING = testing OUTPUT TOO LOW = output voltage too low for succesful completion of the testAD BATTERY = the batteries should be replaced BATT TOO LOW = battery voltage too low to start the testEST OK = battery has been tested with positive result

OTE: the test only gives a reliable result if- the load exceeds >30% of the rated output power,- the batteries are > 95% charged.

f the batteries are dangerously close to being worn out, a low priority alarm 'replace battery' will beenerated (see 3.4.2.2). The batteries must be replaced as soon as possible (see section 6.2).OTE: If the manual test is started immediately after installation or after a power failure, the UPS mayenerate a false 'replace battery' alarm as the batteries have been (partly) discharged during

ransport/storage or during the power failure.

he default setting of the capacity normally results in a reliable runtime prediction. Local circumstancesowever (e.g. low ambient temperature) may cause the prediction to be unreliable. In this case you canave the UPS to recalculate the battery capacity. The predicted runtime shown in the display is 10% lower

han calculated in order to balance out small changes in load, ambient temperature and battery condition.n order to keep track of the capacity deterioration due to aging of the batteries, we advise to perform aattery calibration test at least once per year.

uring a battery calibration test the batteries will be discharged to 'battery low' alarm level (see section.4.2.3 'battery low'). The test will result in a new capacity indication in the second setup screen (see.4.3) and, after complete recharge, new runtime predictions. Please note that immediately after a batteryalibration test the expected runtime time is very short: allow the UPS to recharge its batteries.

.6.6 Deep battery test

his test, initiated by UPS monitoring software, is identical to a 'battery calibration test' (see above).lease refer to the manual of the appropriate monitoring software package for more information.

GE Digital Energy g

Apart from the options described in 4.2 and 4.3 the following options are possible:

5.1 Extended Runtime (NetPro 2000/3000)Extended runtime can be obtained by connecting a separate battery extension pack to the UPS. In thiscase the UPS must be informed about the new total battery capacity to allow a reliable recalculation of theavailable runtime (see section 3.4.3). Dependent of the charge condition of the new batteries the newruntime calculations may temporarily be unreliable.The additional batteries increase the runtime and recharging time for the unit, all other operationalinformation is the same as for standard models. It is not allowed to connect an external charger to theUPS!

5.2 Isolation Transformer (NetPro 2000/3000)Units equipped with a temperature protected isolation transformer ("NetPro +") are housed in a largercabinet than the standard unit. The isolation transformer allows the output neutral to be connected to

- protective earth (default setting)- the input neutral

or be isolated. Please contact your dealer.

5.3 PowerFLAG SerVICe Box for Modem ConnectionIf you connect the PowerFLAG SerVICe Box between the communication port of the UPS and a modem,a programmed number can be dialed in case of a UPS alarm. It also allows service personnel to dial inand check the status of the UPS to perform remote diagnostics. This way service costs, specially inremote areas, can be reduced considerably.

6.1 GeneralThe UPS is virtually maintenance free: take care of proper environmental conditions and keep airinlets/outlets free of dust. Please read 2.1.

6.2 BatteriesThe service life of the battery is from 3 to 6 years, depending on the operating temperature and on thenumber of discharge cycles.

As a healthy battery is critical to the performance of the UPS, an automatic quick battery test is performedregularly to ensure failsafe operation (see section 3.6.4). When the condition of the battery is critical, a'replace battery' alarm will be activated (see 3.4.2.2). Have your dealer replace the batteries as soon aspossible.

NOTE: under certain circumstances a manual battery test can result in a false alarm: please see 3.6.4'quick battery test'.

Regular deep battery tests are advised in order to re-calibrate the capacity of aging batteries. Sections3.4.3 'battery capacity' and 3.6.5 give more information.
