The LP 33 Uninterruptible Power Supply (UPS) provides the energy supply for critical loads which
need a reliable, continuous free from voltage disturbances and frequency fluctuations supply.
In case the mains 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 mains recovers.
LP 33 is a truly On-line double conversion Uninterruptible Power Supply (UPS),
equipped with automatic bypass, where the load is normally supplied by the
inverter.
LP 33 can be configured, if chosen, for the IEM mode (Intelligent Energy
Management) permitting the maximum energy saving.
The main typical performances of the LP 33 system are the following:
• On-line double conversion technology to provide an excellent quality power supply.
• Input power factor 1.
• Input current THD 8%.

3 DESCRIPTION
3.1 PRINCIPAL DIAGRAM AND MAIN ELEMENTS DESCRIPTION
Fig. 3.1-1 UPS principal diagram
The Uninterruptible Power Supply System LP 33 / 10 - 20 - 30 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 On-line
mode.
If chosen the IEM mode, the SSM transfer the load from mains to inverter in case the utility fails.
Back-Feed Protection
All LP 33 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.
On-line 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 On-line 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.
IEM mode operation (Intelligent Energy Management)
When the IEM 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 IEM mode operation
The IEM 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 “On-line mode and IEM mode”, or switching
between operation modes at required time, can be done through the UPS console panel (see
Section 7.3.1-5).
In case of parallel system
IEM mode (Intelligent Energy Management) cannot be enabled for RPA Parallel System.

G
E
OPM_LPS_33E_10K_30K_4CN_V010.doc 13/82 Operating Manual LP 33 / 10-20-30 kVA
Automatic bypass operation
In On-line 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
On-line 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 busbars.

E
OPM_LPS_33E_10K_30K_4CN_V010.doc 14/82 Operating Manual LP 33 / 10-20-30 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 timeout (selectable) the load is transferred to mains.
• With missing bypass mains 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_33E_10K_30K_4CN_V010.doc 15/82 Operating Manual LP 33 / 10-20-30 kVA
3.3 RPA PARALLEL SYSTEM
The RPA (Redundant Parallel Architecture) allows to extend the unit to a parallel system with 2, 3,
or 4 units LP 33 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 rendundancy
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.
Mains Input
Load
Fig. 3.3-1 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 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.
The parallel system exclude 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 busbars.

4.2 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)

4.4 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 air-
conditioning.
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.
NOTE !
Insufficient space on both sides of the UPS in respect to the wall can cause a
dangerous increase of the internal operating temperature.
LP 33 positioning
For easier access in case of maintenance
operation and for a free circulation around the
cabinet, we recommend to maintain the
following minimum distances:
Right & left side: 100 mm (4”)
Rear side: 50 mm (2”)
Top of the UPS: 300 mm (12”)
Right & left side: 200 mm (8”)
Rear side: 50 mm (2”)
Top of the UPS: 300 mm (12”)
Fig. 4.4-1 LP 33 positioning
Fig. 4.4-2 RPA parallel system positioning
NOTE !
Both lateral sides of the UPS MUST BE
ACCESSIBLE at any time for repair or
maintenance.
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.

4.5 VENTILATION AND COOLING
The heat produced by the UPS is transferred to the environment by its internal blowers.
Airflow through the UPS
It is important that the cooling air can freel
y
flow through the air inlets and outlets of the
UPS.
Fig. 4.5-1 Airflow through the LP 33
NOTE !
Insufficient distances on both sides of
the UPS could increase the temperature
inside the UPS.
Do not put any object on the top of the
cabinet: it might obstruct the air flow.
Heat evacuation from UPS room
The heat must be evacuated from the
environment with a proper cooling / ventilation
system provided by the user.
Fig. 4.5-2 Heat evacuation from UPS room
Air volume and losses of the UPS
The approximate minimum air volume needed to evacuate the heat generated by the UPS, for
inlet temperature max. 35°C (95°F), for the standard version at inverter nominal load with PF =
0.8 lag. and battery charged, are the following:
