3.8 Power cable connection
Before installing the equipment, it is necessary to verify the type of input source, that is, if there is
a single or a dual input. In case of dual input, verify the copper bars that connecting bypass and
mains input (rectifier) have been removed.
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.
Remove the distribution rear cover. Choose appropriate power cables (refer to the table above
reported) and pay attention to the diameter of the connection terminal of the cable that should be
greater than or equal to that of the connection poles;
