Electrical installation
4.3.1
External Protective Devices
For safety reasons, it is necessary to install, external circuit breaker at the input A.C. supply and the battery. This
chapter provides guidelines for qualified installers that must have the knowledge of local wiring practices for the
equipment to be installed.
•
External Battery
The UPS and its associated batteries are protected against the effect of over-current through a DC compatible
thermo-magnetic circuit-breaker (or a set of fuses) located close to the battery.
•
UPS Output
Any external distribution board used for load distribution shall be fitted with protective devices that may avoid the
risk of UPS overloaded.
•
Over-current
Protection device shall be installed at the distribution panel of the incoming main supply. It may identify the power
cables current capacity as well as the overload capacity of the system .
4.3.2
Power Cables connection
Once the equipment has been finally positioned and secured, connect the power cables as described in the
following procedure.
Verify the UPS is totally isolated from its external power source and also all power isolators of the UPS are open.
Check to see if they are electrically isolated, and post any necessary warning signs to prevent their inadvertent
operation.
WARNING
Select a thermo magnetic circuit-breaker with an IEC 60947-2 trip curve C (normal) for 125% of the current as
listed below
SINGLE PHASE WORKING MODE
Normally this UPS is wired as 3-phase mains system 3P+N, but also is designed to be powered by single phase
mains P+N, so can be adapted to actual and future installations.
Simply A,B,C 3-phase input terminals must wired be together to convert to single phase mode (P+N)
It is not necessary to change setting inside UPS LCD display.
