Electrical connections

The electrical hook-up of the modular battery cabinet to the UPS is part of the installation that is not normally performed
by the UPS manufacturer. For this reason, the indications that follow are to be considered approximate and it is recom-
mended that the electrical connections are based on local installation standards.
After removing the battery cabinet from the packaging and positioning it in its definitive place, the Skilled Technician can
begin to make the electrical connections.
The electrical hook-up must be done before installing the battery drawers to the cabinet.
WARNING
The choice of cables type and their cross sections depending on the rated current and their installations must be made as indi-
cated by the local installation standards and it is a responsibility of the Skilled Technician.
Check the KEOR MOD UPS installation manual for more information.
