1. STORAGE
If the CPS is not to be installed immediately it must be stored within the original packaging and protected from
moisture and weather. The area used to store the equipment must have the following characteristics:
Temperature: -25°÷ + 60°C (-13°÷140°F)
Relative humidity: 90% max
The recommended storage temperature is between +10° to 30°C (+50° e 86°F).
2. INSTALLATION ROOM
The CPS and its battery cabinet are designed for indoor installation. The following points should be observed when
choosing the place of installation:
 avoid dusty environments;
 ensure that the floor is level and able to support the weight of the CPS and the battery cabinet;
 avoid sites that are too narrow as this may impede normal maintenance operations;
 the ambient relative humidity must not exceed 95%, non-condensing;
 avoid positioning in sites exposed to direct sunlight or hot air;
 ensure that the ambient temperature, with the CPS operating, remains between :
operating temperature: 0 ÷ + 40 °C
maximum temperature for 8 hours a day: + 40°C
mean temperature for 24 hours: + 35°C
Note: - The recommended operating temperature for the CPS and for the batteries life is between 20 and 25°C.
To keep the temperature of the installation room within the range indicated above, a system has to be provided to
remove the dissipated heat (for the value of the kcal/kW dissipated by the CPS refer to the “SPECIFICATIONS”).
3. PRELIMINARY OPERATIONS
3.1 Checking the packaging
When you receive the CPS check that the packaging has not been damaged during transportation. Confirm that neither
of the two anti-shock/tilt devices fixed to the packaging have been activated. If this has happened follow the
instructions provided on the packaging. Be careful when removing the packaging materials so as not to scratch the
CPS cabinet.
The equipment must be handled with care as it could be damaged if it is dropped or banged.
The CPS is supplied with:
 user instruction manual
 CD-ROM with the CPS management software & communications cable

3.2 Positioning
The air enters the CPS through ventilation grills located in the front door and exit through the fan grills located on the
rear panel. The following should be taken into account when choosing a position for the CPS:
 a space of at least one meter must be kept clear in front of the equipment for start-up/shutdown operations and any
maintenance operations that may be required
 leave a minimum distance of 60cm between the top of the CPS and the ceiling of the room, to enable adequate
circulation of the air exiting from the system
 leave a minimum distance of 30cm between the rear of the CPS and the relative wall of the room, to enable
adequate circulation of the air exiting the system
 The AC-DC INPUT/OUTPUT cables enter from the bottom of the CPS. Access to the power and auxiliary
terminals and the switchgear is from the front.
For the mechanical dimension of the CPS refer to the installation diagram supplied with the USER MANUAL
The installation diagram identifies:
- the position of the holes in the base plate through which the equipment can be bolted to the floor;
- the base view to design a pedestal (if the CPS is to be located on a raised floor);
- cable entry position;
- position of the fans on the rear of the CPS.
4. SETTING UP THE ELECTRICAL SYSTEM

(*) 120% load, nominal input voltage and battery recharging. External protection can be inserted at the CPS input..
Ac input
On the incoming mains supply of the the CPS, in the distribution cabinet, must be install a overcurrent protections.
This protection shall be made with fuse type as shows in the table or with equivalent circuit breaker.
For dual incoming supplies, separate protective devices must be installed for the Rectifier and the Bypass inputs.
Battery
ATTENTION
Any battery cabinet must have its own fuses on its output terminals “+” and “-“.
Remember that those fuses must be able to open the dc voltage.
If using the “Rapid” fuse, type gG/gL NH,
the MAXIMUM size of the battery fuse must be below 2 times the nominal battery capacity.
If using the “Ultra Rapid” fuse, type aR NH,
the MAXIMUM size of the battery fuse must be below 2.5 times the nominal battery capacity.
For example: battery type 150Ah we can use 250A gG/Gl or 315A aR.

4.1.1 Residual Current Detector (RDC)
A differential switch (RCD) must be inserted into the mains supply input (CPStream).
The differential switch located CPStream must have the following characteristics:
- Sensitivity 500mA;
- sensitive to d.c and unidirectional pulses (class B)
- insensitive to transient current pulses
- class A or class B
- delay greater or equal to 0,1s
In the standard version, where there is no isolation transformer in the by-pass line, the neutral input from the mains
supply is directly connected to the output from the CPS.
INPUT NEUTRAL CONNECTED TO OUTPUT NEUTRAL
THE ELECTRICAL SYSTEMS LOCATED CPSTREAM AND DOWNSTREAM OF THE CPS ARE IDENTICAL
When operating in the presence of mains supply, a differential breaker (RCD) installed on the input will intervene as
the output circuit is not isolated from the input circuit.
When operating without mains supply (from battery) the input differential breaker will intervene only if it is able to
switch as a result of leakage current without any voltage at its poles (for example a differential breaker with an
auxiliary relay is not suitable). However it is possible to install additional differential breakers on the output of the CPS,
possibly coordinated with those on the input.
4.2 Mains, load and battery connections
THE FOLLOWING OPERATIONS DESCRIBED IN THIS CHAPTER MUST BE PERFORMED BY
TRAINED PERSONNEL.
THE FIRST CONNECTION TO BE MADE IS THE GROUND/EARTH CONNECTION TO THE TERMINAL
MARKED 'PE'. THE CPS CANNOT OPERATE WITHOUT CONNECTION TO THE GROUND/EARTH SYSTEM.
Before connecting, ensure that that the CPS equipment is totally isolated from any external power sources, battery and
mains line, and that all of the CPS switches are open, in particular:
- the CPS mains supply input is completely isolated
- all of the switches on the CPS: SWIN, SWBY, SWOUT, SWMB, are in the OFF position
- the output switch of the battery cabinet is in the open position
- always ensure that no hazardous voltages are present by measuring with a multi-meter.
For the power cable connection to the CPS terminal board refer to installation diagram supplied with USER
MANUAL
