2.6.3 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.
