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.

(*) 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.
