(1) 3.97 BTU / h = 1 kcal / h  
(2) To calculate the air flow rate, the following formula may be used:  Q [m3/h] = 3.1 x Pdiss [Kcal/h] / (ta - te) [°C] 

Pdiss is the power expressed in Kcal/h dissipated by all the devices installed in the installation environment. 
ta= ambient temperature, te=outside temperature. To take leaks into account, the value obtained should be increased by 10%. 
The table shows an example of a flow rate with (ta - te)=5°C and a rated resistive load (pf=1). 
(Note: This formula is applicable if ta>te, only; if the UPS installation does not require an air-conditioning system).

LECTROMAGNETIC COMPATIBILITY

This UPS product conforms to the current electromagnetic compatibility (EMC) regulations (C2 class). It may cause radio interference 
in the home environment. The user may have to adopt supplementary measures. 
This product is for professional use in industrial and commercial environments. Connections to USB must be made with the cable 
provided; the connection to the RS232 (RJ10 connector) have to be made with shielded cables less than 3 metres long.

RELIMINARY 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 described in 
this manual. 

The following operations have to be performed with the UPS disconnected from the power source, switched off 
and with all equipment switches open.  
Before making the connection, open all cabinet switches and verify that the UPS is completely isolated from all 
power sources: battery and AC power supplies. In particular, check that: 
  - the UPS input line is completely disconnected 
  - the UPS bypass line is completely disconnected 
  - the 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 bolt 
marked as PE. 
The UPS must only be operated whilst connected to a suitable earthing system. 

The input Neutral must always be connected. 

ATTENTION: a three-phase 4-wire distribution system is required.  
The standard UPS version must be connected to a 3 Phase + N PE (ground protection) power source.  
Ensuring that the incoming phase rotation is within a clockwise direction. 

ATTENTION: After the installation operations are completed, refit all of the cabinet protection panels using the 
appropriate screws supplied.
