3.1
DESCRIPTION
PRINCIPAL DIAGRAM AND MAIN ELEMENTS DESCRIPTION
Fig. 3.1-1 UPS principal diagram
The Uninterruptible Power Supply System LP 33 Series can be divided into the following main elements:
Electronics
The UPS is designed with a microprocessor–controlled supervision and diagnostic system.
Communication between user and UPS is achieved by the front panel consisting of an LCD screen,
displaying the operation modes, the measurements and the events / alarms.
Rectifier
The rectifier converts the 3-phase mains voltage into a controlled and regulated DC-voltage, supply
power to the inverter and to charge the battery through the battery-charger.
Inverter
The inverter converts the DC voltage into a three-phase sinusoidal with constant amplitude and
frequency, which is completely independent from the AC-input voltage.
Automatic Bypass
The automatic bypass consists of a static semiconductor-switch (SSR: Static Switch Relay), used to
provide an uninterrupted transfer of the load from inverter to mains when operating in VFI (Voltage
Frequency Independent) Mode.
If chosen the ECO Mode, the SSM transfer the load from mains to inverter in case the utility fails.
Back-Feed Protection
All LP 33 Series UPS’s are equipped with an automatic system for the protection against voltage back
feeding towards Utility, through the Bypass (Applied Standard IEC 62040-1).
This protection works automatically by opening contactor K6 (in series with the thyristors of the static
switch) and eventually K7, and acts in case of internal defects of the system, or due to wrong
manipulations on the maintenance bypass Q2.
Manual Bypass
The manual bypass consists of a pair of manual switches Q1 and Q2, which allow the isolation of the
UPS from the load, while still supplying the load with power directly from the mains.
Battery
The battery, normally stored by the battery-charger, supplies the DC energy to inverter in the event of
mains failure.

3.2
OPERATION MODES
This section describes the different possible operation modes of the UPS explaining the function of the
main modules of the UPS.
VFI (Voltage Frequency Independent) mode operation
Under normal conditions the load is
permanently powered by the inverter with
constant amplitude and frequency.
The rectifier, powered by the mains, supplies the
inverter and the battery-charger keeps the
battery fully charged.
Fig. 3.2-1 Energy flow in VFI Mode operation
The inverter converts the DC voltage in a new AC sine wave voltage with constant amplitude and
frequency independently from the input mains power.
ECO Mode operation
When the ECO Mode is selected, and the mains
power is available, the load is normally powered
through the automatic bypass.
When the mains voltage is detected out of the
prescribed tolerances, the load is automatically
transferred to the inverter.
When the mains recovers, the load returns to
the automatic bypass after a variable time
defined by the control unit.
Fig. 3.2-2 Energy flow in ECO Mode operation
The ECO Mode can be configured directly by the user for higher efficiency, considering the mains
reliability and criticality of the load.
The selection between the two operation modes “VFI Mode and ECO Mode”, or switching between
operation modes at required time, can be done through the UPS control panel (see Section 7.3.1-5).
In case of parallel system
ECO Mode cannot be enabled for RPA Parallel System.
Attention:
A single unit equipped with a RPA - Parallel board, must be considered as parallel, thus
disabling ECO Mode.

Operating Manual LP 33 Series / 40-60-80-100-120 kVA
Automatic bypass operation
In VFI (Voltage Frequency Independent) operation
mode, the load is permanently supplied by the
inverter but, in case of trouble on the inverter, or
when overload or short-circuit on the output
occur, if the mains voltage do not exceed the
admitted tolerances, the load is instantly
transferred to the mains through the automatic
bypass, taking advantage of the higher short
circuit power.
Fig. 3.2-3 Energy flow in automatic bypass operation
When the inverter recovers, the load will be re-transferred automatically to the inverter.
In case of parallel system
Each unit has its own bypass.
All the bypasses in the system work together, their control being managed in the same manner by
all units.
The units are continuously exchanging information before taking such decision.
In case the inverter of one unit fails, its bypass remains operating.
It is excluded only if the unit is separated from the common bus by opening its output switch Q1.
Mains recovery operation
As soon as the mains recovers, the rectifier starts
up automatically supplying the inverter and the
battery-charger recharges the battery.
In case the inverter has been shut down following
a complete discharge of the battery, when the
mains recovers the system start up
automatically.
Fig. 3.2-4 Energy flow at mains recovery operation
When the energy stored in the battery is sufficient to ensure a minimum time of operation with the
actual load, in case of a future mains failure, the load will be retransfered to inverter (if selected VFI
Mode).
In case of parallel system
When the AC input power recovers, the rectifiers will start up sequentially according to their
number in the parallel system in order to avoid an initial inrush current.
The inverters will start up automatically, but only when the battery has recharged enough for a
minimum runtime with the present load.
When enough inverters to supply the load have been restarted, the load will be transferred from
the automatic bypass back to the inverter bus-bars.

Page 14/93
Operating Manual LP 33 Series / 40-60-80-100-120 kVA
Manual bypass operation
The manual bypass circuit consisting of Q1 and
Q2 manual switches, permits the transfer of the
load directly to the mains without interruption,
leaving the UPS galvanically separated from the
output load.
This type of operation is normally used when the
UPS system must be completely turned off for
maintenance or reparation.
Fig. 3.2-5 Energy flow in manual bypass operation
Mains failure operation
In the event of a mains power failure, the
rectifier and the battery-charger turn OFF,
while the inverter continues to supply the load
without interruption using the energy stored in
the battery.
During the battery discharge, the LCD screen
displays the remaining autonomy, based on the
battery capacity and the applied load.
Fig. 3.2-6 Energy flow during mains failure operation
In the event of an extended mains failure, before the battery is fully discharged, the alarm “stop
operation” warns the user that the UPS will start the shutdown procedures when the indicated time
expired (normally 3 minutes).
In case of parallel system
With parallel system for power capacity:
• With the bypass mains power available as the warning “battery low” occurs on one unit, after

RPA PARALLEL SYSTEM
The RPA (Redundant Parallel Architecture) allows to extend the unit to a parallel system with 2, 3, or 4
units LP 33 Series connected on the same bus, which ensure the highest reliability rate and increase the
power availability.
Mains Input
Parallel system for power capacity
Two or more units can be paralleled in order to achieve
output power superior to the maximum power
delivered by a single UPS unit.
The maximum total load shared between the n parallel
units can achieve the 100% of the installed nominal
power system.
In the event of one unit fails, the load will be suddenly
transferred to the mains by the bypass.

Parallel system for redundancy
The parallel system can be defined redundant only in
case the nominal power rating of n-1 units of n parallel
units is sufficient to supply the required load power.
The load in a parallel redundant system, is equally
shared by n units connected on the output bars.
F1
Load
Fig. 3.3-1 RPA system diagram
Should one of the parallel units trip off-line, the remaining (n-1) units will share the load maintaining the
applications protected by inverter until the normal situation restores.
Load sharing between parallel units
The control bus exchanging the data between the microprocessors of the paralleled units provide for a
constant proportional load sharing in every load condition.
Management and synchronisation of the parallel system
All the units are identical without master and slaves.
One unit is arbitrarily selected as the reference (the first unit connected on power bus) being this unit the
first synchronised with the mains voltage, and all the other units synchronise with the first one.
In case the reference unit fails or it is excluded from the parallel power bus any other unit will take over
the reference role.
The AC input power source of all the bypasses must be the same for all the units of the parallel system
excluding any phase shift between them.
Control bus of the parallel system
A high-speed serial bus, guarantees communication, synchronization and load sharing between the
UPS modules.
Each module controls it’s own function, while the Master (each unit can be Master) controls and
commands the status of the system.
NOTE !
No transformers, fuses or automatic circuit breakers should be inserted between the
unit’s output and the load common bus-bars.

UPS PARALLELED ON THE SAME BATTERY
NOTE !
A parallel system with a Common Battery for two or more UPS, requires a particular
installation and adequate setting of some parameters, (accessible only through
password), and can therefore only be done by a qualified GE engineer.
Usually each UPS Unit runs with its own Battery.
In case of parallel units running with a Common Battery (max. 4 UPS - see Fig. 3.4-1), the sharing circuit
between the individual UPS is integrated in the communication bus of the system in order to assure an
equal sharing of the Rectifiers output currents.

Pay attention to the following recommendations:
•
The units delivered for this functioning mode needs a special parameters setting, so they must be
prepared in advance before the installation.
•
The installation must be performed only with the UPS system completely shut down.
•
The AC Rectifiers input power (5) must be the same, with clockwise phase rotation for each unit.
•
Each Rectifier must be set for the same floating DC voltage and the same Battery current limitation.
•
It is mandatory to install the fuses / MCB (7) on each line connecting the Rectifiers to the common
Battery for maintenance / safety reasons (see Section 4.7.2).
•
In case a unit must be powered down for maintenance, switch-OFF the concerned unit before open
the DC fuses / MCB on the Battery line (7).
•
It is recommended to connect an external NO free contact “Battery Fuses” to the UPS and to enable
the function by setting the parameter (see Section 7.1).
•
If an emergency generator set supplies the UPS, and the free contact “Generator ON” is connected
to the Customer Interface, connect a separate NO free contact on each parallel unit.
•
The parameters enabling the Battery test, both manual and automatic, must be set in the same
mode on all the units sharing a Common Battery.
•
Do not connect the temperature sensor for automatic battery floating voltage compensation.
•
Do not enable the function Boost charge.

DELIVERY
When delivered, check carefully the package integrity and the physical conditions of the UPS
equipment.
In case of any damage sustained during transport, immediately inform the carrier and contact your
local Service Centre.
A detailed report of the damage is necessary for any insurance claim.
NOTE !
A damaged UPS must never be installed or connected to mains or battery!
4.3
STORAGE
The equipment is carefully packed for
transport and storage so that it is in a
perfect condition when eventually installed.
Never leave an UPS outside the building and
do not store the UPS one on top of the other.
It is recommended to store the UPS in its
original package in a dry, dust free room
and far away from chemical substances,
with temperature not exceeding -25°C to
55°C (-13°F to 131°F).
4.3.1 Storage of the UPS
Some important functions of the UPS, such as the customised functions, are defined by parameters
stored in a RAM memory.
The RAM is supplied by a small backup battery located on the Control Unit board.
If the storage time of the UPS exceeds 1 year, these functions should be verified by an authorised
Service Centre before putting the UPS into operation.
NOTE !
In case of storage of the UPS pay attention to:

4.3.2 Storage of the battery
In case of extended storage, when the delivery includes maintenance free batteries, keep in mind that
they are subject to auto-discharging process.
To avoid permanent damages to the battery, you must observe the following instructions:
•
The storage time without charging the battery depends on the temperature of the storage ambient.
•
The optimal ambient temperature for the batteries is 20°C (68°F).
For storage temperature higher than 20°C (68°F), the storage time will decrease.
•
Each additional 10°C (18°F) over the nominal temperature of 20°C (68°F) will decrease the storage
time, without freshening charge, by half.
In case of a maintenance free battery, the storage time without charging the battery is
approximately:
6 months with storage temperature 20°C (68°F)
3 months with storage temperature 30°C (86°F)
2 months with storage temperature 35°C (95°F)
NOTE !

PLACE OF INSTALLATION
The UPS should be installed in a restricted area where only qualified personnel should be admitted.
The place of installation should be clean, dust-free, and provided with proper ventilation or airconditioning.
Verify for sufficient floor load capacity (see Section 4.1.1).
We strongly advice that the ambient temperature should not exceed 20° ÷ 25°C / 68° ÷ 77°F (max. 35°C
/ 95°F). See Section 4.5.

Clearance around the front of the unit
should be sufficient to enable free
passage of personnel with the doors
fully open, and to allow sufficient airflow
to the door vents.
To guarantee proper cooling air
exhaust, the recommended minimum
clearance between ceiling and top of
the UPS is 400 mm (16”).
A single-phase power outlet (230 VAC)
should be provided near the UPS for
connection of power tools, test
equipment or connectivity devices.
This outlet must be grounded.
The LP 33 Series UPS can radiate radio frequency energy.
Although some RFI (Radio Frequency Interference) filtering is inherent to the UPS there is no guarantee
that the UPS will not influence sensitive devices such as cameras and monitors that are positioned close
by.
If interference is expected, the UPS should be moved away from the sensitive equipment.
NOTE !
Operating temperature is very important for valve regulated battery (maintenance
free).
Operation at temperatures higher than 20°C (68°F) will reduce life expectancy.
Respect the prescription VDE 0510, those of the battery supplier and other local
standards.
The installation and cabling of the battery must be done by qualified people.

ELECTRICAL WIRING
WARNING !
The connections to and from the UPS must be executed by QUALIFIED PERSONNEL
ONLY.
Refer to the “Safety prescriptions - Installation” described on Section 1.
The cabling of the UPS-system has to be done according to the power installed.
Exceptions are only allowed to suit local prescriptions.
For correct rating of fuses and cable sections for input mains, output load and battery, see data
indicated in sections 4.7.2 and 4.7.3.
Before connecting the UPS, verify that the mains voltage and frequency, the output load voltage, the
frequency and the battery data (cells number, floating voltage, autonomy) are according to the local
requirements.
Protection of the UPS mains input, must be exclusively with 3 pole breakers.
The UPS needs the connection of the Neutral to the input, to guarantee the function in TN mode.
Caution when using four-pole circuit breakers as protection to the load of the UPS.
A potential problem exists for situations with non-linear loads: the neutral current could be greater
than the phase currents.
Avoid to run the input cables in parallel with the output cables to prevent them from noise induction.

In order to ensure a correct load sharing between the
parallel units, when the load is supplied by mains, it is
recommended to keep the cable size and length from
the input distribution board to the output bus-bar the
same for each parallel unit.
Mains Bypass input voltage must be the same for all
units, thus avoiding phase shift or phase rotation
problems.
Load
Fig. 4.7-1 RPA Parallel System
To avoid mutual induction effect, the input cables bust
be run in separate conduit from the output cables.
No transformers, fuses or automatic circuit breakers should be inserted
between the unit’s output and the load common bus-bars.
The delivery and installation of fuses and input / output connections of the UPS are at the
customer’s expense, unless agreed otherwise.
NOTE !
In case of non observance of the required minimum distances on both UPS sides (see
section 4.4) it is recommended to provide an additional length of the input/output
cables so that the UPS can be moved for maintenance purpose.
It is recommended to use flexible input/output conductors with suitable length to
admit a sufficient displacement.

4.7.1 Fuse discrimination (co-ordination of breakers tripping)
In order to ensure the circuit selectivity in case of short- circuit at load level, special care must be
taken in choosing the fuse ratings installed in the output distribution.
When a short-circuit on the output occurs, if the mains voltage does not exceed the admitted
tolerances, the load is instantly transferred to the mains through the automatic bypass, taking
advantage of the higher short circuit power.
To ensure a correct co-ordination of the breakers tripping, the fuses supplying the bypass line must be
at least 1,6 time bigger than the largest fuse in the output distribution.
If the selectivity must be ensured also in case of mains failure (that means inhibit automatic bypass),
the largest fuse in the output distribution must be lower than 20% of the UPS rated current for each
phase.

4.7.2 Fuse ratings
If ELCB breakers are prescribed to protect the input connections, consider the high leakage current
towards the earth generated by the noise-suppressor capacitors.
If strongly prescribed, the ELCB breakers should be the largest type suitable for non-linear current and
for delayed operation.

UPS FUNCTIONING AS FREQUENCY CONVERTER
When the UPS LP 33 Series is delivered as frequency converter (different output frequency with respect
to the input frequency), the automatic bypass and manual bypass functions are disabled.
Therefore the load cannot be transferred to mains in case of overload, short circuit, or inverter failure.
In cases where the UPS needs to be powered down for maintenance purposes, the critical load must
also be powered down during this time.
When the set-up parameters of the UPS are set for frequency converter, the ECO Mode operation is
automatically disabled.
The UPS delivered as frequency converter has the following differences:
•
Automatic bypass disabled by setting of dedicated parameter (access protected by password
reserved to service engineer).
•
The handle of the switch Q2 - manual bypass is removed to avoid accidental wrong manipulations.
•
Mains bypass disabled by removing the fuse F3 fitted on the board P2 – Power Supply.
WARNING !
In case a UPS delivered as frequency converter should be set on site for UPS
standard version, the operation must be performed by a qualified service
engineer.
Notices for installation:
•
For UPS with common AC input follows the standard procedure described in Section 4.8.1.
Notices for start up procedures:
•
Follow the standard procedure indicated in Section 8.1.
Notices for shutdown procedures:
•
Follow the standard procedure indicated in Section 8.1.
NOTE !
The inverter can be turned off only by pressing the push-button total off.

Y/N controls the automatic events signalling through modem.
If this parameter is set to Y (yes) the UPS itself will call the remote location when a new
event occurs.
Delay:
This parameter controls the delay between the occurrence of a new event and the
modem dialling.
It is useful because since the events typically do not occur isolated but in certain
sequences, you can eliminate the need for multiple dial-outs for such a sequence of
events.

This parameter (values Y / N) enables or disables the operation
in ECO Mode.
If the value is Y and the current time is in the interval for the current day, the ECO Mode is active.
The activation / disactivation of ECO Mode is indicated each time in the event list.
In order to check the inverter function, at least 1 minute of VFI Mode must be programmed during the
week (the Y / N parameter is automatically disabled if this condition is not satisfied).
In case this minimum time in VFI Mode is not respected, the ECO Mode will be disabled.
If the value is N, the UPS is normally operating in VFI / double conversion mode at all times.

d1 ÷ d7: Enabling time in function of weekdays.
For the weekdays from d1 to d7 (Saturday to Friday) the edit mode (edit day) allows to define time
intervals when the UPS is operating in ECO Mode.
The hour is given in 24-hour format.
These intervals are defined by:
ECM START:
the hour of the day after which the ECO Mode is enabled.
The ECO Mode is enabled until the following ECM STOP time is reached (the ECM
STOP time of the same day if this is later than the ECM START time, the ECM
STOP time of the following day otherwise).
ECM STOP:
the hour of the day before which the ECO Mode is enabled.
The ECO Mode is enabled starting from the preceding ECM START time (the ECM START time of the
same day if this is earlier than the ECM STOP time, the ECM START time of the previous day
otherwise).
Identical times for ECM START and ECM STOP mantain the existing mode only in case the previous
command was ECM START and the following command will be ECM STOP.
3.
HOURS SELECTED:
The number of ECO Mode hours per weekday (from d1 - Saturday to d7 Friday) is displayed in the operation mode parameter window (ceiling
value).
To better understand the ECO Mode programming modes, some typical examples are shown:
Example 1:
Weekday
For continuous ECO Mode set the ECM START times to 00:00 and the ECM STOP times
to 23:59 for all weekdays, but almost 1 day must have 1 minute of VFI programmation:

The ECO Mode is active from 18:00 of weekday d3 - Monday until 06:00 of weekday d4 - Tuesday (as
indicated by the ECM STOP time of weekday d4 - Tuesday).
The ECM STOP time of weekday d3 - Monday has no effect as it is followed by the ECM STOP time of
weekday d4 - Tuesday.
It can be, without change of meaning, any time between 18:00 and 23:59.
Similarly, the ECO Mode is active from 18:00 of weekday d4 - Tuesday until 06:00 of weekday d5 Wednesday.
The ECM START time of weekday d5 - Wednesday has no effect as it is preceded by the ECM START time
of weekday d4 - Tuesday.
It can be, without change of meaning, any time between 00:00 and 06:00.
To avoid undesired ECO Mode operation, verify:
• Date and Time (first page of parameter).
• ECO Mode screen how many hours of ECO Mode operation have been selected for
each day of the week.
NOTE !
The ECO Mode becomes active only if the load is supplied from inverter.

PROCEDURES FOR SINGLE LP 33 Series
8.1.1 Start-up of the LP 33 Series
Before connecting hazardous voltages, make sure that:
• The connection to the electrical system has been performed by qualified personnel;
• The equipment frame has been correctly grounded to the main earth;
• Make sure that mains input protection is removed;
• All the panels removed to allow the UPS connection have been correctly reinstalled;
• The UPS switches Q1 and Q2 are OFF (Pos. 0);
• The external battery fuses are removed.
This procedure must be performed for the first start-up following the installation, with the UPS
completely switched Off and not powered.
This procedure presupposes that the load is not yet supplied by the UPS system.
NOTE !
The UPS can be started-up using the battery supply in case the input mains should be
unavailable.
To avoid an incidental battery discharge, it is recommended to proceed to the UPS
start-up having the input mains available.
1.
Switch ON the mains power at the input distribution panel.
As a result the UPS performs a self-test and the LCD will show
the following screen:
EXECUTING MAINBOARD
SELF TEST
00000000000
SELF TEST OK!
NOTE !
In case the alarm “4410 - Mains bypass out of
tolerance” persists, check the phases rotation of
the input mains.

PROCEDURES FOR PARALLEL SYSTEM LP 33 Series
8.2.1 Parallel System start-up of the LP 33 Series
Before connecting hazardous voltages, make sure that:
• The connection to the electrical system has been performed by qualified personnel;
• The equipment frame has been correctly grounded to the main earth;
• Make sure that mains input protection is removed;
• All the panels removed to allow the UPS connection have been correctly reinstalled;
• The UPS switches Q1 and Q2 are OFF (Pos. 0);
• The input fuses rectifier F1, F2, F3 and battery fuses F9, F10, F11 is removed.
This procedure must be performed for the first start-up following the installation, with all the units
completely switched Off and not powered.
This procedure presupposes that the load is not yet supplied by the UPS system.
NOTE !
The UPS can be started-up using the battery supply in case the input mains should be
unavailable.
To avoid an incidental battery discharge, it is recommended to proceed to the UPS
start-up having the input mains available.
1.
Switch ON the mains power for each unit at the input
distribution panel.
As a result each unit performs a self-test and the LCD will show
the following screen:
EXECUTING MAINBOARD
SELF TEST
00000000000
SELF TEST OK!
The LCD screen will display the number of the unit in the parallel
system (P1, P2, P3 or P4).
NOTE !
In case the alarm “4410 - Mains bypass out of
tolerance” persists, check the phases rotation of
the input mains.

Customer Interface
The Customer Interface allows the client the exchange of information
(monitoring and control) with the following interfaces:
- Serial port RS232.
- 6 programmable output channels.
- 2 programmable input channels, of witch one for GEN-ON.
- EPO (Emergency Power Off).
Advanced SNMP Card
Simple Network Management Protocol
The Advanced SNMP Card is an Interface to the Ethernet Network, and
provides UPS information via the standard SNMP protocol.
The UPS can therefore be managed by a Network Management System (NMS)
or by our applications (for instance JUMP), which uses this information to
determine the state of the UPS in order to guarantee safe and orderly
shutdown of the server, when needed.
Connectivity Software
JUMP Software Suite / IRIS Service, etc.
Software application for the control and monitoring of the UPS.

Gen Set signalling
If an Emergency generator set supplies the UPS in case of utility failure and the generator is particularly
unstable in frequency, it should be suitable to install the signal “generator on” on terminals X1 / 11, 22
(Normally Open voltage-free contact) or on connector J2 / 11, 24 (see Fig. 10.2.1-1 / X1 and J2).
Since the Parameter for of the reading of the Generator function is password protected, call the nearest
Service Centre for it's activation.
When this contact closes, it causes the change of certain settable functions such as:
•
Enabling or disabling of synchronisation and consequently the load transfer to generator.
•
The battery recharge inhibition during the generator operation, or after what delay from generator
start the battery will start to be recharged.
Consult your nearest Service Centre for more information.

NOTE !
To enable this function, remove jumper JP3 on the Customer Interface and the
cable on the terminal X2 / 1, 2 (see Fig. 10.2.1-2).
Verify if the cable on the terminal X7 / 1, 2 and jumper JP5 on the P1 – Control
board are OFF (see Fig. 10.2.1-3).
In a parallel system a separate NC (Normally Closed) contact must be connected
individually to each unit.
When activated, this switch causes the immediate shutdown of booster, battery-charger, inverter; and
the contactors K4, K6 and K7.
NOTE !
This procedure could imply a load shutdown.
When the EPO has been activated, the system must be restored as following:
•
Press the push-button EPO (contact on X2/1, 2 is closed again).
•
Perform the command INVERTER OFF entering the screen:
MENU/COMMAND MENU/INVERTER OFF.

MAINTENANCE
WARNING !
All maintenance and service works must be performed by QUALIFIED SERVICE PERSON.
11.1 GENERAL MAINTENANCE
A UPS system, like other electrical equipment, needs periodic preventive maintenance.
A regular maintenance check of your installation guarantees higher reliability of your safe power
supply.
Preventive maintenance work on the UPS can be done only by trained Service technicians.
We therefore recommend you sign a Maintenance and Service contract with the local Service Centre
organisation.
11.2 COOLING FAN MAINTENANCE
The expected operational life of the cooling fans is approximately 40’000 hours of continuous
operation.
A high ambient temperature will shorten this operational life.
11.3 BATTERY MAINTENANCE
The service life of the battery is from 3 to 6 years, depending on the operating temperature and on the
number of discharge cycles.
The UPS LP 33 Series offers the possibility of SBM (Superior Battery Management).
The function SBM can be activated through a service Parameter.
The functionality of SBM reduces the Battery recharging time together with improved lifetime of the
Battery.
As a healthy battery is essential to the performance of the UPS, an automatic or manual battery test
can be performed regularly to ensure failsafe operation, in order to check if the battery can provide the
expected backup time in case of mains failure.
We recommend the battery test be performed at least every 1 month, especially if the battery is not
sufficiently discharged during normal operation.
Since the parameter enabling the battery test protected by user password, please contact your Service
Centre for more information.
Please consider that, if you did a full battery test to verify the full runtime of the battery, the charger
needs at least 8 hours to recharge the battery up to 90% of its capacity.
To guarantee that the battery is fully charged, the UPS system should be in operation for at least 12
hours every 3 months.
When the condition of the battery is critical, the warning signal will be activated (general alarm, buzzer
and alarm message “4118 - Battery fault”).
In this case the battery must be replaced as soon as possible.
Please contact your Centre Service.

SERVICE REQUIRED
If this lamp lights up during the normal operation (service
parameter with password), the performances of the UPS remain the
same, but that means the unit has not been serviced for the last
20’000 hours by a qualified GE Service Engineer.
Some components of the UPS which need periodic maintenance, if not replaced, could cause a
reliability reduction of the supply system.
We highly recommend that you contact your Service Centre for preventive maintenance work.
NOTE !
Ask to your local Service Centre to submit the form of Preventive Maintenance
Contract suitable for your specific needs.
