4. ELECTRICAL INSTALLATION
NOTE!
Before carrying out any operations on the unit read the 'Safety standards' chapter carefully.
WARNING!
Before carrying out any operations, ensure that:
• The switch located inside the battery cabinet is open;
• The UPS is not live and all mains or battery switches are open;
• The switches upstream of the UPS are open.
Use 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
electrical compatibility 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, capacity, 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, please correct the settings.
IMPORTANT!
Protective earthing conductor (PE) must have sufficient current-carrying capacity. The PE cable
core size has to be chosen according to the PROTECTIVE CURRENT RATING of the earth circuit
which depends on the provision and location of overcurrent protective devices. We suggest
35mm² for Masterys Battery Cabinet.
