OPERATING MODE
MODULAR UPS SYSTEM
A Modular UPS System is intended to ensure a perfect supply voltage for the equipment connected to it, both with and without a
power supply network. Once connected and powered, the system generates an alternating sinusoidal voltage, with stable
amplitude and frequency, regardless of surges and/or variations affecting the electrical supply.
With no mains power, the system will power the load by taking energy from the batteries. When the batteries run out, the system
will switch off. When the mains power is restored, the load will be automatically powered according to the AUTORESTART setting.
The Modular UPS System features three types of cabinets: Modular UPS Power Cabinet, Modular UPS Combo Cabinet and
Modular Battery Cabinet, whose main functions and features will be highlighted within this manual.
The Modular UPS System can operate with different modes:
NORMAL MODE
During the NORMAL MODE, the system operates in On Line double conversion. This mode provides the maximum protection
level for the load, the energy coming from the supply network (AC), is converted in order to provide a clean and stable output. The
voltage supplied to the load is a perfect sine wave, with the frequency and voltage independent of the incoming mains supply (VFI
technology). During this mode, the batteries are constantly maintained in a charged condition.
BATTERY MODE
When the AC power network falls outside the pre-set tolerances, for example, in case of a blackout or voltage or frequency
fluctuation, the system automatically switches to the BATTERY MODE and takes power from the batteries to support the load.
When the AC network is again clean and stable, the system returns back to the NORMAL MODE operation.
The Power Walk-In function can be activated through the configuration software. This function allows, upon reconnection to the
network (following a supply failure), a progressive absorption of power from the incoming supply, in order to avoid stressing (due
to the inrush current) a generator which is installed upstream (if fitted). The duration of the transition mode can be set between 1
to 125 seconds. The default value is 10 seconds (when the function is enabled). During the transition mode the required power is
partially collected from the batteries and partially from the network whilst maintaining a sinusoidal take-up. The battery charger is
switched on again when the transition mode ends.
AUTOMATIC STATIC BYPASS MODE
During this operation mode, the load is directly powered by the AC supply, therefore, any input disturbances will directly affect the
connected load.
ECO MODE
In order to optimise efficiency, in ECO (1) mode, the load is normally powered via bypass (any disturbances that occur within the
supply network can affect the connected load). In the event of a mains power supply failure or if the power supply is not within the
pre-set tolerances, the UPS will switch to normal ON LINE operation with double conversion. Approximately five minutes after the
power supply returns within tolerance, the load is switched back to bypass.
FREQUENCY CONVERTER MODE
The system can be configured in this mode to generate a fixed output frequency different from the input frequency. In this
configuration the bypass line will be automatically disabled.
EFFICIENCY CONTROL MODE
The EFFICIENCY CONTROL mode(1) improves the system overall efficiency, particularly at low loads, while preserving the ON
LINE mode and the configured redundancy level. The PMs that are not required to support the applied load are placed in a low
consumption state. In the event of a mains power supply failure or if the power supply is not within the specified conditions, all of
the PMs switch to normal ON LINE operation with double conversion. If there are any sudden and/or high load increases, the
system continuity is guaranteed with a possible temporary transfer to bypass.
NOTE: The Home Page always displays the active operating mode.
(1) These operating modes can only be selected via the “Expert” user profile (see “Access level selection”)

18
MANUAL BYPASS MODE
Transferring the Modular UPS system into the MANUAL BYPASS MODE must be performed as follows to ensure that power to
the connected load is not lost.
Caution: if the system is in battery mode, operation of the Manual Bypass may disrupt the power to the connected load.
1. Close the Manual Bypass SWMB disconnection switch located behind the door: at this point the input is directly
connected to the output.
2. During this mode of operation, any disturbances or blackouts within the power supply line will impact the connected load
(the Modular UPS Cabinet is no longer active, and the load is directly connected to the mains supply network).
3. The display will show that the system has now been transferred to Manual Bypass.
Transferring the Modular UPS Cabinet from the MANUAL BYPASS MODE to NORMAL MODE must be performed as follows to
ensure that power to the connected load is not lost (perform this only if no anomalies or malfunctions are present and if the system
is operational):
1. Ensure that the Bypass Module (see the “Modules and Units” chapter) is present and switched on.
2. Open the SWMB disconnection switch by rotating the handle anti-clockwise.
3. The Bypass Module will activate and then the entire Modular UPS Cabinet will be switched on.
MODULAR UPS POWER CABINET
The Modular UPS Power Cabinet PWC 130X may contain up to 5 Power Modules (PM15X or PM25X) and one Bypass Module
(BM126X).
PMs are UPSs connected in parallel in order to increase reliability in the supply of power to the connected load and to increase
the power available at the output (ref. to the "Modules and Units" chapters)
The load that can be applied to a Modular UPS Cabinet can be higher than the load that can be sustained by each unit thanks to
automatic power-sharing. Increased reliability is only achieved on condition that the total system power, with one or more PMs
deactivated, remains higher than the demand. This condition is always achieved by adding at least one redundant PM to the
minimum number of elements required to power the load, so that after the automatic exclusion of a faulty PM, the power supply
can continue as required.
Each PM is equipped with a smart control unit, connected through a data bus with the other PMs within the system, achieving a
high reliability distributed logic.
Note: the redundancy level required by the PMs may be set-up during the initial configuration.
The Bypass Module (BM) operates as the central AUTOMATIC BYPASS for the whole Modular UPS Cabinet (ref. to chapter
“Modules and Units”).
In order to further increase the power of the system, multiple Modular UPS Power Cabinets can be connected in parallel, up to 4.
The maximum configuration will therefore be 20 PMs connected in parallel.
WARNING: The SWMB disconnection switch installed within the Modular UPS Cabinet is not a maintenance
bypass switch, therefore, there are dangerous voltages within the Cabinet, even if this disconnection switch
is closed.
CAUTION: Contact a service centre should any malfunctions be detected. Maintenance can be carried out
only by skilled staff authorised by the manufacturer.
CAUTION: dangerous voltages can be present inside the device, even if the input, bypass, output and
battery switches are open.
The removal of any panels from the Modular UPS Cabinet by non-skilled personnel is a source of danger
and may cause damage to the operator, to the equipment and to the load connected to it.

MODULAR BATTERY CABINET BTC 170
The Modular Battery Cabinet consists of 9 shelves, each of which may contain 4 Battery Units (BU). The BU contains 10 x 12V
batteries (refer to “Modules and Units” chapter).
The Modular Battery Cabinet has an electronic supervision system which, through voltage and current sampling, is able to
measure the condition and any anomaly within each of the Battery Units. The collected data is sent to the system through a data
bus and shown on the display of the Modular UPS Cabinet.
In addition, within the Modular Battery Cabinet there is an SWBATT disconnection switch which enables the BUs to be
disconnected from the Modular UPS Cabinet. The cabinet also features an opto-isolated input which enables the SWBATT switch
to be opened remotely.
CAUTION: each shelf of the Modular Battery Cabinet can be filled (with the 4 BUs) based on the autonomy requirements
of the system (up to a maximum of 9 shelves). The minimum number of fully populated battery shelves must follow the
rules set out in the table below:
