THE MODULAR UPS POWER CABINET INSTALLATION
INSTALLATION ENVIRONMENTS
The Modular UPS Power Cabinet is manufactured for an internal environment.
Essential Requirements:
- avoid dusty environments;
- the relative humidity must comply with the data in the table within this page;
- the operating ambient room temperature must comply with the data in the table within this page;
- avoid environments exposed directly to sunlight and hot air.
To regulate the ambient temperature within the UPS location at the appropriate range, waste heat disposal
systems must be used. Methods which can be used include:
- natural ventilation;
- forced ventilation, recommended if the external temperature is lower (e.g. 20°C) than the temperature at
which you want to operate the UPS;
- air conditioning system, recommended if the external temperature is higher (e.g. 30°C) than the
temperature at which you want to operate the UPS.

PRELIMINARY INFORMATION FOR INSTALLATION
ALL OPERATIONS DESCRIBED IN THIS SECTION MUST BE PERFORMED BY QUALIFIED AND TRAINED
PERSONNEL ONLY.
Our Company assumes no liability for damages caused by incorrect connections or operations not
contained in this manual.
The following operations have to be performed with the UPS disconnected from the power mains, off
and with all equipment switches open.
Before making the connection, open all cabinet switches and verify that the UPS is completely
isolated from power sources: battery and AC power line. In particular, check that:
- the UPS input line is completely disconnected
- the UPS bypass line is completely disconnected
- the external UPS battery line switch/fuses are open
- all UPS switches are in the open position
- check with a multimeter that there are no dangerous voltages
The first connection to be made is the protective conductor (earth wire), this must be connected to
the bar marked as PE.
The UPS must operate while connected to the earthing system.
The input Neutral must always be connected.
ATTENTION: a three-phase four-wire distribution system is required.
The standard UPS version must be connected to a 3 Phase + Neutral + PE (ground protection) power
line.
Comply with clockwise phase rotation.
Read the battery box manual before connecting the batteries.
Check that the total battery voltage meets the requirements of the UPS (refer to the Battery Box
nameplate).
ATTENTION: the maximum length of the connection cables to the Battery Box is 10 meters.
ATTENTION: After the installation operation is complete, refit the cabinet protection panels using the
appropriate screws.
ELECTROMAGNETIC COMPATIBILITY
WARNING: This is a category C2 UPS product. In a residential environment, this product may cause
radio interference, in which case the user may be required to take additional measures.
BATTERY ROOM VENTILATION
The room where the battery box is located must have enough ventilation to ensure the concentration
of hydrogen produced is within safe limits.
The room should preferably be ventilated naturally; if it cannot be, forced ventilation may be
employed.
Standard EN 50272-2 regarding air exchange provides that the minimum aperture must satisfy the
following equation:
A = 28 x Q = 28 x 0.05 x n x Igas x C10 (1/10³) [cm²] where:
A = area of opening [cm²]
Q = airflow required [m³/h]
n = number of battery cells;
C10 = battery capacity in 10 hours [Ah]
Igas = gas producing current [mA/Ah]
according to the standard:
Igas = 1 in backup charging for VRLA type batteries
Igas = 8 in fast charging for VRLA type batteries
NOTE: read the User Manual before using the Maxsis RXR.

POSITIONING INFORMATION
MAXSIS RXR POSITIONING
Warning! The cabinet cannot be moved and/or delivered on site with Power Modules inserted.
When positioning, take into account that:
- the cabinet must be positioned without the Power Modules inserted, the Power Modules can only be inserted once the cabinet
feet have been lowered.
- the wheels are to be used for final positioning only. Specialist moving equipment must be used to transport the UPS near to
the final position.
- plastic parts and the door are not able to act as pushing points or handles.
- you will need to ensure at least enough free space in front of the power cabinet for user operation and maintenance (≈1.5 m).
- no objects should rest on the upper part of the UPS Power Cabinet.
Warning!
The cabinet must be positioned on a level floor.
Ensure that the floor can support the total weight of the system.
The weight of the Power Cabinet full of Power Modules is 420 kg.
A
fter positioning, lower the four feet at the floor, using an appropriate spanner.
Ensure that the total weight of the cabinet is distributed on feet only (the revolving wheels must be lifted from floor).
Ensure that the Power Cabinet is level.
It is possible to reuse the brackets for pallet fastening (slides) to anchor the Power Cabinet to the floor.

THE RATED VOLTAGE AND CURRENT, AS SHOWN IN THE TABLES AND ALSO COMPLY WITH
LOCAL AND NATIONAL REGULATION FOR MAXIMUM POWER RATING
THE PROTECTIVE EARTHING CONDUCTOR (PE) MUST BE CONNECTED PRIOR TO
CONNECTING ANY INPUT / OUTPUT CABLES
SHORTCIRCUIT PROTECTION
UPS in BYPASS OPERATION: the load is instantly switched to the bypass line (l2t=145000A2s): the input line is
connected to the output without any internal protection.
UPS in INVERTER OPERATION: the UPS protects itself supplying 2.5 times nominal current to the output for the
first 0.2 s, which is then reduced to 1.5 times nominal for 0.3 s. After this time (0.5 s) it switches off.
BACKFEED PROTECTION
Cabinet is equipped with an internal protection system which, if a backfeed is detected, cuts the bypass line (through a
metal contactor). If backfeed is detected, the load is powered by the inverter, also during the battery operation.
DIFFERENTIAL SWITCH
In the absence of an input separating transformer, the neutral from the mains power supply is connected to the neutral of
the UPS output. This way the neutral regime of the equipment is not modified.
The input neutral is connected to the output neutral. The distribution system that powers the UPS is not modified by the
cabinet.
CAUTION: make sure that the equipment is connected correctly to the input neutral, otherwise
damage to the UPS may be caused.
DUAL INPUT
The neutral for the input line and bypass line are shared inside the device.
A single differential switch must be fitted upstream of the point at which the line divides to supply the standard inputs and
bypass inputs for the cabinet.
When operating from mains power, a differential switch located at the input can trip as the output circuit protection is not
isolated from the input circuit.
In addition, other differential switches can be inserted on the output, possibly coordinated with the switches at the input.
The differential switch located upstream must have the following features:
- DIFFERENTIAL CURRENT ADJUSTED TO THE SUM OF THE UPS CABINET + LOAD. WE STRONGLY
RECOMMEND MAINTAINING AN ADEGUATE MARGIN TO AVOID DELAYED ACTUATION (1A MINIMUM
CURRENT)
- TYPE B
- DELAY GREATER THAN OR EQUAL TO 0,1s

CONNECTING ANY INPUT / OUTPUT CABLES
SHORTCIRCUIT PROTECTION
UPS in BYPASS OPERATION: the load is instantly switched to the bypass line (l2t=1620000A2s): the input line is
connected to the output without any internal protection.
UPS in INVERTER OPERATION: the UPS protects itself supplying 2.5 times nominal current to the output for the
first 0.2 s, which is then reduced to 1.5 times nominal for 0.3 s. After this time (0.5 s) it switches off.
BACKFEED PROTECTION
Cabinet is equipped with an internal protection system which, if a backfeed is detected, cuts the bypass line (through a
metal contactor). If backfeed is detected, the load is powered by the inverter, also during the battery operation.
DIFFERENTIAL SWITCH
In the absence of an input separating transformer, the neutral from the mains power supply is connected to the neutral of
the UPS output. This way the neutral regime of the equipment is not modified.
The input neutral is connected to the output neutral. The distribution system that powers the UPS is not modified by the
cabinet.
CAUTION: make sure that the equipment is connected correctly to the input neutral, otherwise
damage to the UPS may be caused.
DUAL INPUT
The neutral for the input line and bypass line are shared inside the device.
A single differential switch must be fitted upstream of the point at which the line divides to supply the standard inputs and
bypass inputs for the cabinet.
When operating from mains power, a differential switch located at the input can trip as the output circuit protection is not
isolated from the input circuit.
In addition, other differential switches can be inserted on the output, possibly coordinated with the switches at the input.
The differential switch located upstream must have the following features:
- DIFFERENTIAL CURRENT ADJUSTED TO THE SUM OF THE UPS CABINET + LOAD. WE STRONGLY
