3 INTRODUCTION
3.1 GENERAL DESCRIPTION
The LP 33U Series Uninterruptible Power Supply (UPS) provides the energy supply for critical loads
which need a reliable, continuous, and free from ‘voltage disturbances and frequency fluctuations’
supply.
In case the utility fails, or it exceeds the permitted tolerances, the energy to supply the load is furnished
by the battery with a backup time dependent on its capacity, until the utility recovers.
LP 33U Series is a truly VFI double conversion Uninterruptible Power Supply (UPS),
equipped with automatic bypass, where the load is normally supplied by the inverter.
LP 33U Series can be configured, if chosen, for the ECO Mode permitting the maximum
energy saving.
The main typical performances of the LP 33U Series system are the following:
• VFI (Voltage Frequency Independent) double conversion technology to provide an excellent
quality power supply.
• Input power factor >0.98.
• Input current THD <10%.
• Automatic bypass and manual bypass to improve reliability and maintenance.
• Microprocessor controlled supervision.
• Dual AC inputs (optional).
• ECO Mode operation.
• Compact and agreeable design expressly conceived for “Office environment”.
• Low level acoustic sound, 65 dB (A) (50 & 60 kVA) to avoid noise to the persons operating in the
same environment.
• Multi-language LCD screen.
• Total battery management: SBM (Superior Battery Management)
• High battery capacity, 9 minutes (50 kVA) and 8 minutes (60 kVA), with battery housed in the
UPS cabinet.
• Wide rectifier input voltage tolerance: 177 - 229 VAC (Line-Line).

4 DESCRIPTION
4.1 BLOCK DIAGRAM AND MAIN ELEMENTS DESCRIPTION
Fig. 4.1-1 UPS block diagram
The Uninterruptible Power Supply System LP 33U Series / 50 & 60 kVA 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, in order to
supply power to the booster, and to charge the battery through the battery-charger.
Inverter
The inverter converts the DC voltage into a three-phase AC-voltage 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 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 33U 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.

4.2 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 utility, supplies the
inverter and the battery-charger keeps the
battery fully charged.
Fig. 4.2-1 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 utility power.
ECO Mode operation (Intelligent Energy Management)
When the ECO Mode is selected, and the utility
power is available, the load is normally powered
through the automatic bypass.
When the utility voltage is detected out of the
prescribed tolerances, the load is automatically
transferred to the inverter.
When the utility recovers, the load returns to the
automatic bypass after a variable time defined
by the control unit.
Fig. 4.2-2 Energy flow in ECO Mode operation
The ECO Mode can be configured directly by the user for higher efficiency, considering the utility
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 5.3).
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.
Modifications reserved Page 14/65
OPM_LPS_3UO_50K_60K_1US_V010.doc Operating Manual LP 33U Series 30 & 40 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 utility voltage do not exceed the
admitted tolerances, the load is instantly
transferred to the utility through the automatic
bypass, taking advantage of the higher short
circuit power.
Fig. 4.2-3 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.
Utility recovery operation
As soon as the ‘utility’ 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 utility recovers the system start up
automatically.
Fig. 4.2-4 Energy flow at utility 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 utility failure, the load will be retransferred 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.

OPM_LPS_3UO_50K_60K_1US_V010.doc Operating Manual LP 33U Series 30 & 40 kVA
Manual bypass operation
The manual bypass circuit consisting of Q1 and
Q2 manual switches permits the transfer of the
load directly to the utility 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. 4.2-5 Energy flow in manual bypass operation
Utility failure operation
In the event of a utility 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. 4.2-6 Energy flow during utility failure operation
In the event of an extended utility 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 utility power available as the warning “battery low” occurs on one unit, after
timeout (selectable) the load is transferred to utility.
• With missing bypass utility power as the warning occurs on one unit, the system starts the
timeout (selectable) of “Stop operation” and then the output load shuts down.
With redundant parallel system:
• As the warning battery low occurs on one unit unnecessary to support the present load, after
timeout (selectable) this unit shuts down and the load is shared between the other units.
As the warning occurs on one unit necessary to support the present load, the system starts the
timeout (selectable) of “stop operation” and then the output load shuts down.

OPM_LPS_3UO_50K_60K_1US_V010.doc Operating Manual LP 33U Series 30 & 40 kVA
4.3 RPA PARALLEL SYSTEM
The RPA (Redundant Parallel Architecture) allows to extend the unit to a parallel system with 2, 3, or 4
units LP 33U Series connected on the same bus, which ensure the highest reliability rate and increase
the power availability.
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.

Fig. 4.3-1 RPA system diagram
The load in a parallel redundant system, is equally shared by n units connected on the output bars.
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 synchronization 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 synchronized with the mains voltage, and all the other units synchronize 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 !
The parallel system excludes more rectifiers connected on common battery.
No transformers, fuses or automatic circuit breakers should be inserted between
the unit’s output and the load common bus bars.

4.4 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).
• 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.
• Do not connect the temperature sensor for automatic battery floating voltage compensation.
• Do not enable the function Boost charge.
