2 - Introduction
2.1
Description
More than ever before, today's advanced electronic equipment, with complex integrated circuits and other
sensitive electronics, needs a stable and continuous AC power supply to operate correctly. While the power
coming from the wall outlet is often unreliable, a GE Digital Energy™ LP-U UPS provides the security of
completely uninterrupted power.
A compact, truly on-line system, the LP-U UPS protects your equipment from all forms of power interference,
including complete power failure. A simple and elegant circuit design, together with extensive protection against
abnormal operating conditions (e.g. overload, short circuit, overheating), makes the UPS exceptionally reliable.
The UPS offers complete galvanic isolation of input and output, also when operating in bypass mode. As a
result, input and output voltages do not necessarily have to be equal, making the UPS suitable for almost every
situation.
All units are standard equipped with a backfeed protection relay.

3 - Functional Explanation
3.1
The Principles of Operation
The UPS stores electric energy in batteries. This allows the UPS to supply output power even when the
incoming utility power is cut off completely.
Energy is stored as Direct Current (DC), while input and output energy must be Alternating Current (AC).
Therefore the UPS contains an input converter (AC to DC) and an output converter (DC to AC). (fig.2)
3.2
Normal Conditions
Under normal conditions, energy from the utility is channeled through the input converter, which supplies the
output converter and the battery charger. The batteries are kept in a fully charged state, and the output
converter synthesizes a completely new AC output sine wave to supply the load (electrical equipment).

3.3
Utility Failure
In the event of a utility power failure (i.e. absent or outside tolerance) the system uses the energy reserve
stored in the battery to continue to produce AC power, ensuring unbroken output (fig. 3). No interruption or
alteration will ever be noticed in the output power.
In the event of an extended utility failure, the output converter will stop when the battery has been discharged.
At this point, the UPS is no longer able to power the connected equipment.
When the utility is re-established within tolerance, the output converter will be supplied again by the input
converter and the batteries will be recharged, making them ready to support future power failures.

3.4
Automatic Bypass Switch
If the output converter is unable to deliver the demanded output power because of overload or
overtemperature, the automatic bypass switch will automatically transfer the load to the utility. When the
situation is corrected the UPS will switch back to normal operation, i.e. the load is tranferred back to the output
converter. Though the automatic bypass switch is shown as a simple mechanical switch in figures 2-5, the
transfers are done by means of thyristors, i.e. electronically, without any interruption of the power supplied to
the load.
In case of a severe overload or short-circuit the magnetic bypass circuit breaker (rear panel) may trip in order to
protect the UPS. If the current is insufficiently high to trip the breaker, the UPS will be switched off by the
software in order to protect the UPS and connected equipment.’

If a power failure occurs during bypass operation, load power may be lost. If the UPS functions under overload
conditions it may not be able to protect the load.

Manual Bypass Switch (Service switch)
The system can be bypassed manually using the manual bypass switch located at the rear panel. It is a two-
position switch: the normal position is '1': as in figures 2-4. Position '2' is the service position: the load is directly
connected to the utility input. This way maintenance of the UPS (e.g. battery replacement, as in fig. 5) is
possible without interruption of the power supplied to the load.
CAUTION: REFER SERVICE TO QUALIFIED PERSONNEL ONLY.
THE RFI FILTERS AND OUTPUT TRANSFORMER ARE ALWAYS ACTIVE.

4.5.5 Installation of GE Digital Energy™ LP-U battery extension pack(s)
The numbers between (brackets) refer to figures 19-21 in section 5.1.
Battery extension pack(s) are shipped with all materials necessary to connect them to the UPS. The pack(s)
can be connected to the DC connector (15) at the rear panel of the UPS. Be sure to switch off the UPS before
proceeding: be sure that the UPS can be switched off without causing damage to the load, and turn all circuit
breakers (7-8-9) into ‘off’ position (down).
1. Open the DC fuse holders at the rear of the battery
pack (16) and make sure that the fuses have been
removed.
1a. Open the DC fuse holders at the rear of the UPS (16)
and make sure that the fuses have been removed.
2. UPS rear panel: loosen the screws, and remove the
cover plate (11) and conduit box (17).
CAUTION! The battery voltage is 240Vdc
and is NOT isolated from the utility.
3. Break out the indicated part of the conduit box, fix the
1
1a
gland of the DC cable in this opening.
4. Connect the DC connector of the battery pack (15a)
to the DC socket of the UPS (15). Be sure that the
colours match. You will hear a click when the cable is
properly installed.
5. Re-install the cover plate and conduit box.
6. In case of 14Ah battery packs: using the DC
connector of the battery pack (15) you can install a
second, third, etc. pack. 7Ah battery packs cannot be
connected in parallel.
2
NOTE: A maximum of two Digital Energy™ 14Ah
battery cabinets can be connected without additional
fusing. Every two additional Digital Energy™ 14Ah
battery cabinets must be connected over a 60Amp
fuse, rated for 300Vdc.
NOTE: Third party battery cabinets must be
connected over a 60Amp fuse, rated for 300Vdc,
using the Digital Energy™ external battery cable
(order separately).

7. Insert the 2 (7Ah) or 4 (14Ah) DC fuses of the (each)
battery pack, insert the DC fuses of the UPS and
close the fuse holder(s) of battery pack and UPS (16).
8. In order to calculate the available back-up time
related to the actual load, information on the capacity
of the battery set is stored in the UPS. As the total
battery capacity changes when battery extension
packs are installed, the battery capacity must be re-
programmed. See 5.3.4.
In case of a custom-built battery extension set you may
want to install a ‘battery disconnected’ alarm device.

4.5.6 LP 11U series: 2 / 3 / 4 parallel operating units – additional info
The RPA option (Redundant Parallel Architecture) allows you to create a redundant UPS system in which 2, 3
or 4 LP-U units operate in parallel. The following should be considered when installing units in parallel.
This section gives aditional information on:
- installation (4.5.6.1)
- start-up (4.5.6.2)
- use / maintenance (4.5.6.3)
4.5.6.1 Notes concerning installation of a parallel system
1.
All inputs of the UPSs must be supplied from the same phase. This is to enable bypass operation of the
parallel system. All inputs must be individually protected by fuses in the installation. The values of these
fuses should correspond to the values mentioned in section 4.5 table 1.
2.
All outputs must be connected together, supplying the load. It is advised to install switches (S 1-4, fig. 17)
in the output wiring, in order to be able to isolate a unit from the remaining system for service and
maintenance purposes. It is advised to make a Neutral-to-Ground bounding in the output junction.
3.
4.
The diameter of input and output cables must be according to the table in the installation drawings (see
appendix). Cables with different diameters can cause tripping fuses in the UPS and/or the installation.
The length of all input cables from the input junction (Li, fig. 17) to the UPS inputs should be equal. The
same applies to the cables from the outputs to the output junction (Lo, fig. 17). The minimum length of
the input as well as the output cables is 3 meters / 10 feet.

5.
The right option slot (14) at the rear of the unit contains the the RPA-card. Before the parallel system can
be put into operation a unique number has to be appointed to each UPS in the system. This can be 0, 1,
2 or 3. Start with 0 for the first unit, 1 for the second, 2 for the third and 3 for the last unit:
-loosen the screws, remove the RPA-card
-set the dipswitch to the appointed number (fig. 18)
-re-install the RPA-card, fasten the screws.
Do NOT install the network cables between the RPA-cards of the units yet!
Figure 18. Appointing a unique
number to each UPS in the system
6.
In the UPS many parameters can be set. It is advised to keep the same setting for each parameter in
each UPS in the parallel system. In any case the following parameters are critical and should have equal
settings:
-autorestart (on/off, see 5.3.3)
-output voltage (120/208/220/230/240 Vac, see 5.3.4)
-output frequency (50/60 Hz, see 5.3.4)
It is absolutely required that these parameters are set to the same value. Off factory this is the case. If
you’re not sure that the units have equal settings:
-be sure that the RPA-cards of the units have not been interconnected yet
-be sure that utility power is connected to the UPS
-start each unit individually (see 5.2), check / change the parameters, and switch the unit off again.
7.
Interconnect the RPA-cards of the units, using the network cable that came with the UPS. See figure 17
(dotted line). Only install the cables that were delivered with the UPSs! Of the first and the last UPS in
the system only one RPA-socket is used to interconnect the UPSs. A bus terminator must be placed in
the other (free) RPA-socket. The required bus terminators have been delivered with the unit.
4.5.6.2 Notes concerning starting up the parallel system
For starting up the system please refer to section 5.2.
After switching on all units the LP UPSs will show the following display:
AUTORESTART OFF
PRESS ENTER
After pressing the ‘Enter/Reset’ button on one of the units the system will start up. All units will display the
standard screen. The number in the lower right corner indicates the number of the UPS in the system.

5.2 Start-up
The numbers between (brackets) refer to figure 19 in section 5.1.
Note: the UPS can be started on battery power if the utility input voltage is not available or if circuit
breaker ‘utility’ is in off-position: simply skip step 1. To prevent accidental discharging of the batteries, it
is however recommended to proceed with step 1 and start the unit only when the utility input voltage is
available.
1.
2.
Turn breaker 'utility' (8) and breaker 'bypass' (9), both on the rear panel, into position ‘on’ (up).
Some UPS parameters (e.g. voltage, frequency, LCD language) are user selectable. If you want to
change one or more settings, please refer to section 5.3.4 ‘Set-up Menu’ now. Changing the settings
later is possible, however only after switching off the unit.
3.
Turn switch 'UPS on/off' (rear panel, 7) into position ‘on’ (up).
The green LED 'operation' (front panel, 5) will illuminate.
After switching on the UPS performs a self-test and the display (front panel, 1) will show:
SELFTEST
IN PROGRESS
After completion of the self-test the output voltage of the UPS is available and the unit is ready for use.
The display will show the default screen: model and actual load (values are examples)
LP 5-11U
LOAD 37%
In case of a system failure the self-test results in a failure message; this message is displayed for 30
seconds before the self-test is repeated automatically. If the faulty situation persists, switch off the UPS
and contact your dealer. See chapter 9 for more information.
4.
5.
Though the batteries (the internal energy reserve) were fully charged when the UPS left the factory, they
might have lost some energy during transport and/or storage. It is recommended to allow the UPS to
recharge the batteries for a few hours. This way you ensure that the UPS can provide sufficient runtime
in case of a utility power failure.
If not yet switched on, the equipment connected to the UPS can be switched on now; operate as usual.

5.3 Use
Once the unit is in operation, there is no need to switch the unit on/off during use.
If the manual bypass switch (rear panel, 10) is in position '1', switching off by the on/off switch (rear panel, 7)
results in a total absence of the output voltage (also the bypass voltage) of at least 5 secs.
If an emergency shutdown switch has been installed (see 4.5.1.1-2, step 6) the UPS will stop immediately
when the switch is opened. Restart is only possible after closing the switch and turning the UPS off and on
again with the UPS on/off switch (rear panel, 7).
The UPS is operated via the push-buttons (front panel, 2-3-4) and the LCD display (front panel, 1). Furthermore
the UPS can be controlled via the RS232/contact interface port (rear panel, 12a). For more information see 6.1.

Depressing the 'up’ key from the standard alarm screen shows, in priority order, which alarms are active,. Scroll
through the screens with the 'up' and 'down' keys. Alarm message texts can succeed each other. The following
messages are possible:
The output capacitor C2 is defective. Contact your dealer.

The load exceeds the rated output power of the UPS, and the output voltage
can no longer be guaranteed. This text alternates with the following screen:
UPS OVERLOADED
REDUCE LOAD
showing the actual load as % of the nominal UPS rating. These messages are
displayed if the load is > 100%.
UPS OVERLOADED
LOAD 143%
If the load exceeds 150% the UPS will immediately switch to bypass,
assuming that the conditions for a transfer to bypass are fulfilled. If an
overload condition between 100-150% persists, the UPS can eventually also
switch to bypass operation due to temperature protection. If a transfer to
bypass is inhibited (due to voltage or frequency errors of the utility supply) the
UPS may automatically switch off within a few seconds (load dependent).
Output power is lost at that moment. To avoid these problems, be absolutely
certain that the power demands of the protected equipment are within the
limits of the UPS.
The temperature of the heatsinks or output transformer is too high. As a result
the output voltage may be transferred to bypass.

The operating temperature can rise to intolerable levels as a result of:
•

If the UPS operates in 'on line' mode, it will switch to bypass until the
temperature is normal again. If however the UPS operates 'on battery', a
shutdown will occur and output power is lost.

5.4.3 Deep Battery Test
The runtime as shown on the LCD screen is calculated, and the value is initially based on the capacity of new
batteries. As batteries age, their capacity deteriorates, and as a result the initial battery capacity may be too
unreliable for a proper runtime prediction. The UPS is able to keep track of the aging process, if a 'deep battery
test' (battery calibration test) is executed regularly. During such a test the condition of the batteries is tested,
and the result of the test is stored, and used by the UPS system for future runtime calculations.
We advise performing a deep battery test on a regular basis. For accuracy reasons the interval should depend
on the number of discharges . With one discharge per month a 6 month interval is sufficient. If the discharge
interval is shorter than once a week a monthly deep battery test is advised.
A deep battery test can be started only if the following conditions are met:
-
-
-
The load should be more than 30% of nominal load
The batteries should be fully charged (100% on screen)
There are no alarms at the time the test is started.
Procedure:
From the standard menu first enter the service menu (press the 'down' and 'Enter/Reset' keys simultaneously
for 2 seconds). Subsequently press the 'down' key until the following screen appears:
CALIBRATE BAT
press DOWN+ENTER
Press the keys ‘down’ (2) + 'Enter/Reset' (3) simultaneously, for at least 1 second.
The following screen appears:
CALIBRATE BAT
TEST ACTIVATED
The test is executed, this may take a few minutes with standard battery and full load. Partial load and/or batt.
extension packs can lengthen the test period considerably. Do not change the load during the test, i.e. do not
switch off or on connected equipment!
The deep battery test discharges the batteries to 'battery low' alarm level (see section 5.3.2 'battery low').
Please note that immediately after a deep battery test the expected run time is very short: allow the UPS to
recharge its batteries.
After the test the second line informs about the result:

5.5 Other Features
5.5.1 Shutdown
'Remote shutdown': Using communication capabilities, the computer can direct the UPS to turn itself off
following controlled shutdown of the system. Subsequently the UPS will remain off for at least a few seconds
(see also 6.1). LED 'operation' will blink green. The unit will start up again as soon as the utility returns.
'No-load shutdown': The UPS will also switch off if the load is < 2% of the maximum load, and the input is
absent for more than 10 minutes. For more information see section 5.3.2, message 'SHUTDOWN ALARM'.
NOTE: If the UPS operates in parallel, the no-load function is not available.
'Emergency shutdown': for more information see section 5.3.2, message 'IMMEDIATE SHUTDOWN'.
5.5.2 Utility start
The UPS is able to start, even if the batteries are not connected. Alarm messages 'BATTERY FUSE FAILURE'
and 'BATTERY DEPLETED' will be shown. The run time is zero.
5.5.3 Sleep and wake-up
GE Digital Energy™ UPS monitoring software allows you to program a 'sleep period' of the UPS by sending
two commands to the UPS:
- shut down after # minutes, and subsequently:
- shut down during # hours.
After the first command the following screen appears:
During the sleep period the output voltage is no longer available. LED
'operation' blinks green, and the LCD screen shows the time left until
restart:
PROG. SHUTDOWN
WITHIN 0:09:17
If a utility failure occurs during the sleep period and the battery voltage
eventually drops below 200Vdc, the UPS will automatically switch off in
order to save battery power. When the main returns the UPS will start up
automatically. The programmed sleep time however is lost.
PROG. SHUTDOWN
LEFT 0:14:03
The sleep period can be cancelled by either turning the UPS ON/OFF switch (6) off for a few seconds or by
sending the appropriate command via the RS232/SNMP port.
5.5.4 Overload protection in bypass mode
The UPS will protect itself in case of overload. Upon an overload which is caused by abnormal circumstances
the UPS will switch to bypass operation, and subsequently the bypass input fuse on the front panel will trip. The
capacity of the bypass fuse allows it to handle the inrush currents of the equipment connected to the UPS. The
fuse will only trip after more than an hour at an input current of 40Amp (LP 5/6-11U) or 50Amp(LP8-11U) or
63Amp (LP 10-11U).
In order to protect the UPS system the software will cut off the abnormal current:
in 10 minutes:
36Amp
55Amp
in 1 minute:
49Amp
65Amp
LP 5/6-11U:

Between 36-49Amp(LP 5/6-11U), 55-65Amp (LP 8-11U), 70-81Amp(LP 10-11U) the time is inversely
proportional to the input current. We advise to place a distribution fuse slow blow type between UPS input and
the utility supply. Please refer to the installation drawing.

5.5.5 ECO-mode
The UPS is equipped with the ‘ECO-mode’ feature. If the feature is enabled, the load is operated on utility
through the electronic bypass switch. If the utility is interrupted or out of limits the load is automatically
transferred to the inverter. Operating the load on utility improves the efficiency of the UPS with 5-8% and saves
on energy costs. We advise not to use the ECO-mode in case of an unstable utility.
After enabling the ECO-mode (please refer to service screens 5.3.3) the standard menu changes to:
LP 5-11U
LOAD 37%
ECO
NOTE: If LP-U units operate in parallel, the ECO-mode feature is not available.
5.5.6 Auto restart
If this feature is enabled and the unit has shut down (e.g. due to overload) the UPS will start up automatically
when the normal situation is restored. The off-factory setting is: enabled.
If the auto restart feature is disabled the unit will not automatically restart when the normal situation is restored
but the display will show:
AUTO RESTART OFF
PRESS ENTER
After ‘Enter’ the unit will restart. See also 5.3.3 ‘service screens’.
5.5.7 Superior Battery Management
-
Load dependent battery-end voltage: The allowable final battery voltage depends on the discharge
current: the higher the current, the lower the 'end-of-discharge' battery voltage. This gives maximum
capacity without over discharging. Over discharging results in failure to recover normal capacity and in
shortened battery life.
-
-
Equalize mode: When switched on for the first time the UPS will start boost-charging the batteries for 15
hours in order to equalize all battery voltages.
Boost mode: If after a discharge the battery voltage is lower than 240Vdc, the UPS will charge the
batteries with a boost charge voltage of 285Vdc. This enables fast recharging of the batteries. The
programmed battery charging mode will change from boost charge into float charge after boost charging
twice.
-
Temperature compensated battery charging: This feature reduces the battery charge voltage with
increasing temperature (-18mV/°C or -32.4mV/°F per 12V battery). As a result poor charging of the
batteries under low temperature conditions and overcharging of the batteries under high temperature
conditions are prevented.

software supports most common operating systems incl. Novell, UNIX, VMS, Windows 3 - 95/98/2000 - NT,
IBM OS/2, LINUX, has a modular and layered architecture and works for all degrees of network complexity:
stand-alone, multi-vendor networks and large managed networks.
During a power failure the UPS software takes a number of actions: processes are stopped, open files are
closed and unattended systems will be shut down in a controlled way. When the utility power returns, the
systems will automatically start up and will be up and running as soon as possible.

6.2 Emergency shutdown
The emergency shutdown connector is located on the RS232/contact interface card (12). Be sure that the UPS
is switched off, and remove the card from the unit*. Remove the wire from connector J3 (pin 3 and 4). Install the
wiring of a normally closed contact to connector J3 (pin 3 and 4). Re-install the RS232 interface card. If during
normal operation of the UPS the contact is opened, the UPS will shut down. To restart the unit, restore the
connection and turn the UPS off and on again.
* If the card is removed during normal operation the UPS will shut down.
6.3 Relay Card (optional)
The relay plug-in card can be installed in the middle option slot (rear panel, 13). The card is provided with four
potential free contacts representing: battery low, bypass active, utility failure and general alarm. For more
information please refer to the user manual that comes with the interface card.
6.4 SNMP Interface (optional)
This SNMP plug-in card can be installed in the middle option slot (rear panel, 13). The card makes the UPS
‘SNMP manageable’: it allows the data interface to be connected directly to an Ethernet network (thin coax,
twisted pair, AUI). For more information please refer to the user manual that comes with the interface card.
When this option is installed the RS232 communication link is no longer available.

7 - Optional Features
7.1 Extended Runtime
Extended runtime versions are equipped with additional separate battery packs to increase the runtime of the
unit. Additional batteries will increase the recharging time for the unit. All other operational information is the
same.
If a battery pack is connected, the UPS must be informed about the new total battery capacity to allow a reliable
recalculation of the available run time. Please refer to section 5.3.4 ‘Set-up Menu’. Dependent of the charge
condition of the new batteries the new run time calculations may temporarily be unreliable.
Connecting an external charger may cause damage to the UPS. As the batteries are not galvanically separated
from the utility input, the external charger must be galvanically separated from the utility. Using an external
charger will cause a false run time prediction during charging time, the correct run time will be shown 10 hours
after reaching battery float charge. If you are in doubt, contact your dealer.

7.2 Plug-in Cards
An option slot (rear panel, 13) allows easy installation of a relay or SNMP plug-in card. See sections 6.3 and
6.4 for more information.
7.3 RPA-Facility (Redundant Parallel Architecture)
Nowadays there are many mission-critical applications that need a fault tolerant, 100 % reliable availability of
mains power. By adding the RPA-facility to the UPS (rear panel, 14), highest standards for reliability can be
met. The RPA-facility allows to connect 2, 3 or 4 units in parallel.
Connecting GE Digital Energy™ LP-U units in parallel is attractive for several reasons.
Redundancy: To achieve the highest possible level of power protection in a fault-tolerant network.
By connecting units in parallel, using the N+x system, a redundant system can be created. In this case all the
UPSs equally share the load in the system during normal operation. In this way every possible single point of
failure will be eliminated. This means that if one of the UPSs in the parallel system fails, the other(s) can still
supply the load guaranteeing full protection without any interruption.
Scalability: To add power if needed without investments beforehand.
Another reason for paralleling units is upgrading the power rating of the system. If e.g. a LP 5kVA is installed,
the power rating can be upgraded to 10kVA by adding another LP 5kVA in parallel. This spread investment
makes sure that you don’t have to invest in advance, but only when you need to.
GE’s unique RPA system has the following major advantages:
•
RPA offers true redundancy because not only the power electronics are redundant, but also the
batteries, the bypass circuit and the control logic,
•
The RPA system is an option: you don’t have to buy it if you don’t need it.

8 - Maintenance
8.1 General
When used properly, the UPS is virtually maintenance free other than keeping the air inlets/outlets free from
dust.
8.2 Cooling fan
The expected operational life of the cooling fans is approximately 20,000 to 40,000 hours of continuous
operation. A high ambient temperature will shorten this operational life.
8.3 Batteries
The service life of the battery is from 3 to 6 years, depending on the operating temperature and on the number
of discharge cycles.
As a healthy battery is essential to the performance of the UPS, an automatic battery test is performed regularly
to ensure failsafe operation (see section 5.4.1). When the condition of the battery is critical, the warning signal
will be activated (buzzer 1x per 8 secs, and alarm message 'Replace battery', see 5.3.2). The batteries must be
replaced as soon as possible. Please contact your dealer. Use only UL recognised batteries (BAZR2), valve
regulated types.
NOTE: under certain circumstances a manual battery test can result in a false alarm: please see section 5.4.2
'QUICK BATTERY TEST'.
Regular deep battery tests are advised in order to re-calibrate the capacity of aging batteries. See section 5.4.3
for more information.
NOTE: All maintenance and service work, including battery replacement, should be performed
by qualified service personnel.
For authorized service personnel only:
Never short the battery terminals. Shorting may cause the battery to burn. Avoid charging in a sealed container.
Proper disposal of batteries is required: refer to your local codes for disposal requirements. Never dispose of
batteries in a fire: they may explode. Never disassemble or reassemble batteries; their contents (electrolyte)
may be extremely toxic. If exposed to electrolyte, wash immediately with plenty of water, if eye contact occurs
flush with water and contact a physician.
8.4 Safety
CAUTION:
When the LP-U UPS is operating, all parts of the electronics are directly connected to the utility and
high voltages are present on all internal parts, including the battery. Even after disconnection from the
utility, all parts inside the UPS, including the battery, conduct dangerous voltages (except the RS232
output).
For your safety, only authorized service personnel may remove the cabinet cover.
8.5 Storage
Always store the UPS in a dry location with the batteries in a fully charged state, storage temperature must be
within -20 and +45°C. Storing the unit for a period exceeding 3 months can reduce the life of the batteries. To
maintain their normal life expectancy, the batteries must be recharged periodically:
-
-
if the storage temperature is within -20 and +30°C (-4°F and 86°F): every 6 months, for 24 hours,
if the storage temperature is within -20 and +45°C (-4°F and 113°F): every 4 months, for 24 hours.
8.6 Recycling the UPS at the end of service life
NOTE: This product has been designed to respect the environment, using materials and components
respecting eco-design rules. It does not contain CFCs (Carbon Fluorine Chloride) of HCFCs (Halogen
Carbon Fluorine Chloride).
GE Digital Energy, in compliance with environment protection recommends that the UPS equipment,
at the end of its service life, must be recycled conforming to the local applicable regulations.
WARNING
The batteries contain lead, which is a dangerous substance for the environment. Therefore the
batteries must be recycled correctly by specialized companies.

9 - Troubleshooting
Whenever a malfunction occurs, first check external factors (e.g. connections, temperature, humidity or load) to
determine whether the problem is caused by the unit itself or by its environment. Subsequently check whether
the breakers/switches on the rear panel (fig. 19, 7-8-9) are in ‘on’ position. Always check these external factors
before concluding that your UPS is faulty.
The front screen will indicate the problem and solution (if the problem is due to environmental circumstances). If
the solution is not shown on the screen, please contact your dealer.
During the self-test, performed immediately after start-up, the UPS may detect a system failure. In this case a
message is displayed for 30 seconds before the self-test is repeated. If the faulty situation persists, please
contact your dealer.
(One of) the following messages can be displayed:
SELFTEST FAILURE
PCB POWER SUPPLY
One or more voltages of the internal power supply is (are) outside
tolerance. Please contact your dealer.
An external AC voltage (not the UPSs output voltage) was detected on the
output terminals. Please contact your dealer.
SELFTEST FAILURE
