Connecting the UPS Power cables
Power cables connect to screw terminals on a terminal block that is located
behind the rear mounted cable box (see figure). Permanent wiring must be
routed to the cable box using appropriate materials as required by local codes.
Connection of optional remote battery cabinets
Full installation instructions are provided with these cabinets. Safety/EMC
certification limits the use of these terminals to Liebert supplied options.
Properly grounded (earthed) equipment provide multiple benefits
High quality ground (earth) connections are required for the equipment ground
conductors (protective earth) and grounding electrode conductor (power system
earth connection) to reduce electrical noise and provide for safe operation of the
UPS and connected loads. Conduit used alone without a grounding conductor
wire is not an acceptable connection. Size ground (protective earth) conductors
equal to circuit conductors.
