Distribution box electrical connections
Electrical connections are made through a removable power distribution box that attaches to the rear of the UPS.
 PD2-CE6HDWRMBS fits the 5000 and 6000VA models of the Liebert GXT4
 PD2-CE10HDWRMBS fits the 10,000VA model of the Liebert GXT4
The installer must provide an upstream branch circuit breaker. The input circuit breaker on the distribution box and
the output circuit breaker on the rear of the power distribution box disconnect all power between the main cabinet and
the distribution box.
Models equipped with a manual bypass breaker pass bypass power directly to the bypass breaker from the input
terminal block. The input circuit breaker on the distribution box does not disconnect power from the manual bypass
breaker.

Conduit entry holes are provided on the rear and side of the box. Input and output wiring should not share the same
conduit. Emerson recommends using strain relief when installing the wire.
