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. The
cables enter the UPS through a Gland Plate attached to the rear of the UPS. The Gland Plate must first be removed and
drilled to suit the glands or bushes for the cables used. Ensure that the glands are sized so that they hold the cables
securely.

Safety earth cable
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.

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.
