3.8 EXTERNAL BATTERY CABINET CONNECTION.
If the UPS has internal batteries, connecting external battery cabinets is forbidden.
Position the battery cabinet next to the UPS.
Before carrying out any operation, ensure that:
• the UPS is not live,
• all mains or battery switches are open,
• the switches upstream of the UPS are open,
• the battery fuses located inside the battery cabinet are open.
• Remove the terminal boards protection.
• Connect the ground cable ( gure 3.8-1).
• Connect the cables between the UPS terminals and the battery cabinet terminals, strictly observing the polarity of
each individual string ( gure 3.8-1) and the cross-sections indicated in the table at page 12.
Use double insulated cables or the cables supplied with the unit to connect the UPS to the Bat-
tery cabinet. The lenght L of battery cable must not be more than 8 metres long (if L > 8 m, please
contact the support service).
Cabling errors with inversion of the battery polarity may cause permanent damage to the equip-
ment.
• Replace the terminal board’s protection.
If using cabinets not supplied by the SOCOMEC UPS, it is the installer’s responsibility to check the
electrical compatibility and the presence of appropriate protection devices between the UPS and
the battery cabinet (fuses and switches of su cient capacity to protect the cables from the UPS
to the battery cabinet). As soon as the UPS is switched on (before closing the battery switches)
the battery parameters (voltage, capacity, number of elements, etc.) must be veri ed accordingly
on the mimic panel menu. If the values indicated on the battery cabinet data plate are di erent
from those shown on the mimic panel, use the SERVICE > CONFIGURATIONS menu to correct the
settings.
