2. UNPACKING AND INSTALLATION OF THE UNIT
2.6.3. EXTERNAL BATTERY CABINET connection
WARNING!
Before carrying out any operations, ensure that:
• the battery fuses located inside the battery cabinet are open;
• the UPS is not live and all mains or battery switches are open;
• the switches upstream of the UPS are open.
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.
If using cabinets not supplied by the UPS manufacturer, it is the installer’s responsibility to check the electrical
compatibility and 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,
capacity, number of elements, etc.) on the mimic panel menu. See 5.3.6 paragraph for battery settings configuration.
In the case of external batteries, the minimum number of elements permitted is 20 per branch for 120 kVA and 19
per branch for 100 kVA.
