OPERATING MODE
MODULAR UPS SYSTEM
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 electric supply.
The Modular UPS System features two types of cabinets: Modular UPS Power Cabinet and Modular Battery Cabinet, whose main
functions and features will be highlighted in this manual.
Every Modular UPS System appliance was designed and manufactured to be durable. It has however to be recalled that they are
electric power equipment and, as such, they require regular maintenance. Furthermore, some of the components have, inevitably,
a fixed life cycle, they must therefore be regularly checked and replaced, if the conditions requires it: in particular batteries, fans
and in some cases electrolytic capacitors.
It is therefore recommended that a preventative maintenance program is implemented and performed by specialized staff licensed
by the manufacturer.
Our Service Department is at your disposal for customizing preventative maintenance options to suit your requirements.
NORMAL MODE
During the NORMAL MODE, the system operates in the On Line double conversion mode. This mode provides maximum
protection for the load, in fact the energy coming from the network (AC), after it is converted, is clean and stable in the output. The
load voltage supply is a perfect sinewave, with frequency and voltage independent of the incoming mains supply (VFI technology).
And more, in this operation mode the batteries are constantly kept in charged state.
BATTERY MODE
When the AC power network is not within the pre-set tolerance, for example, in case of blackout or voltage or frequency
interferences, the system automatically switches to the BATTERY MODE operation collecting energy from the battery source.
When the AC network is clean and stable again, the system switches 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 an autonomy period), a progressive absorption from it, in order to avoid stressing (because of the inrush current)
a generator unit installed upstream, if any. 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 keeping the 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 interference impact fully on the
load.
- 13 -
MANUAL BYPASS MODE
CAUTION: The SWMB disconnection switch installed on 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 the closure panels of the Modular UPS Cabined by non-skilled personnel is a source of
danger and may cause damage to the operator, to the equipment and to the consumers connected to it.
Order of the operations to be carried out for configuring the Modular UPS Cabinet in the MANUAL BYPASS MODE status without
any cut-off of the power to the load.
Caution: if the system is in battery operation, the Manual Bypass insertion may cut off power to the load.
Close the Manual Bypass SWMB disconnection switch located behind the door: in this way the input is in short-circuit
with the output.
Under this operation mode, any disturbance or blackout on the power supply line will impact on the supplied equipment
(the Modular UPS Cabinet is no longer active and the load is directly connected to the network).
The display will show the completed switch to Manual Bypass.
Order of the operations to be carried out for restarting the Modular UPS Cabinet and closing the MANUAL BYPASS MODE without
cutting off the power to the load (execute only if no anomalies or malfunctions are present):
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 knob anti-clockwise.
3.
The Bypass Module activates and then the whole Modular UPS Cabinet is switched on.
MODULAR UPS POWER CABINET
The Modular UPS Power Cabinet may contain up to 7 Power Modules (PM) and one Bypass Module (BM).
PMs are UPSs connected in parallel in order to increase reliability in the supply of power to the load and the power available on
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. Said 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 in a correct manner.
Each PM is equipped with a smart control unit, connected through a data bus with the other PMs of the system, achieving a high
reliability distributed logic.
Note: any redundancy of the PMs may be set-up during configuration, but, in the case of a Modular UPS Power Cabinet equipped
of all the 7 PMs, one of them is marked in any case as redundant.
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 be therefore 28 PMs connected in parallel, of which at least 4 are redundant.
CAUTION: the Modular UPS System has only a single battery supply, therefore all the Modular UPS Cabinets must share
their batteries.

A wring diagram of the Modular UPS Power Cabinet is provided below.
- 15 -
MODULAR BATTERY CABINET
The Modular Battery Cabinet consists of 9 shelves, each of which may contain 4 Battery Units (BU). The BU contains 10 of 12V
battery packs (ref 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 of each BU. The collected data are sent to the system through a data bus and shown on
the display of the Modular UPS Cabinet.
Furthermore, on the Modular Battery Cabinet there is a SWBATT disconnection switch which allows to disconnect the BUs from
the connection line to the Modular UPS Cabinet. The cabinet features also an opto-isolated input which allows the remote opening
of the SWBATT.
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 the complete battery shelves must follow the
rule on table:

MODULAR UPS COMBO CABINET
The Modular Combo Cabinet may contain up to 3 Power Modules (PM), 1 Bypass Module (BM) and 5 battery shelves. Each shelf
may contain 4 Battery Units (BU). Each BU contains 10 of 12V batteries. Refer to “Modules and Units” chapter.
PMs are UPSs connected in parallel in order to increase reliability in the supply of power to the load and the power available on
output.
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. Said 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 in a correct way.
Each PM is equipped with a smart control unit, connected through a data bus with the other PMs of the system, achieving a high
reliability distributed logic.
Note: the redundancy of the PMs may be set-up during 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 Combo Cabinets can be connected in parallel, up to
4. The maximum configuration will be therefore 12 PMs connected in parallel, of which at least 4 are redundant.
CAUTION: the Modular UPS Combo System can use internal batteries, external batteries or both. The system must share
all internal and external batteries. It’s mandatory to use MPW Battery Cabinets as external battery source if internal
Battery Units are used. Is not allowed to connect other types of external batteries if internal Combo batteries are used.
The Modular Combo Cabinet has an electronic supervision system which, through voltage and current sampling, is able to
measure the condition and any anomaly of each Battery Unit. The collected data are sent to the system through a data bus and
shown on the display of the Cabinet.
Furthermore, on the Modular Combo Cabinet there is a SWBATT disconnection switch which allows to disconnect the BUs from
the connection line to the Modular UPS Cabinet. The cabinet features also an opto-isolated input which allows the remote opening
of the SWBATT.

LOAD LEVEL AND REDUNDANCY SYSTEM STATUS
Multi Power display represent in the home page a graphic bar showing the load level and the system redundancy
Load level: The bar is a comprehensive representation of the number of PM set including their status in function of load level,
and operative conditions, as below shown:
PM configured and necessary to
supply the load
PM configured but not necessary
to supply the load
PM configured but not available
to supply the load
NOTE:
Every full colored box in the bar represent the system load level with 42 kW step.
Whenever the installation includes one or more power cabinet in parallel the bar show the system load level and not the single
cabinet load level.
Redundancy: To increase the system reliability customer can add a number of additional PM (redundant PM) rather than just fit
those strictly necessary to supply the load.
All PM, including the redundant units operate together sharing the load.
Thanks to this reliable feature, we warmly recommend to set one or more redundant PM according with the power needed and
the installation type.
With a power cabinet full equipped (seven PM) at least one unit should be set as redundant unit.
Below are portrayed the possible bar status (six PM operating in the examples) according with the system conditions in function
of load level, redundancy and PM availability.
