2. UNPACKING AND INSTALLATION OF THE UNIT
2.9. EXTERNAL BATTERY CABINET CONNECTION
Position the battery cabinet next to the UPS.
Before carrying out any operations ensure that:
• the battery fuses located inside the battery cabinet are open;
• the UPS is not live;
• all mains or battery switches are open;
• the switches upstream of the UPS are open.
• Remove the terminal board protection.
• Connect the ground cable (figure 2.9-1).
• Connect the cables between the UPS terminals and the battery cabinet terminals, strictly observing the polarity of each individual
string (figure 2.9-1) and the cross-sections indicated in table 2.3.
Use double insulated cables or the cables supplied with the unit to connect the UPS to the battery cabinet.
Cabling errors with inversion of battery polarity may cause permanent damage to the equipment.
• Replace the terminal board protection.
If using cabinets not supplied by the UPS manufacturers, it is the installer’s responsibility to check electrical compa-
tibility and the presence of appropriate protection devices between the UPS and the battery cabinet (fuses and
switches of sufficient 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 must be verified accordingly (voltage, capa-
city, number of elements, etc.) on the mimic panel menu. If the values indicated on the battery cabinet data plate are
different from those shown on the mimic panel use the SERVICE > CONFIGURATIONS menu to correct the settings.
