3DESCRIPTION
3.1BLOCK DIAGRAM AND MAIN ELEMENTS DESCRIPTION
Fig. 3.1-1 UPS block diagram
The Uninterruptible Power Supply System LP 33 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 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.

Operating Manual LP 33 Series 50 & 60 kVA |
3.2OPERATION 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 (Intelligent Energy Management)
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 Fig. 3.2-2 Energy flow in ECO Mode operation defined by the control unit.
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 6.3.1-5).
|
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. |

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 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_0US_V010.doc |
Operating Manual LP 33 Series 50 & 60 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.
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. 3.2-5 Energy flow in manual bypass operation
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.

3.3RPA 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.
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. 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 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 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 bus bars.

3.4UPS 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 / MCCB (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 / MCCB 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.
