3.4 Connection of Power Cables
CAUTION! Only authorized person has to install or maintain UPS / batteries.
The AC input of the UPS should be supplied by a separate line from the AC distribution board.
The input/output cables can be sized to suit the modules rating according to the table below.
The connections of the electric panel should be supplied by grounded outlet. Cables enter the UPS modules
via entry panels in the base of cabinet. All control cables should be screened and run in a separate trunking
to the power cables.
The input/output cables can be sized to suit the modules’ rating according to the table below.

NOTES:
The neutral conductor should be sized for 1,5 times the output/bypass phase current.
The Earth conductor should be sized at 2 times the output/bypass conductor (this is
dependent on the fault rating, cable lengths, type of protection etc.) These
recommendations are for guideline purposes only and are superceded by local
regulations and codes of practice.
