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.
!
WARNING
Risk of electric shock. Can cause injury or death.
The UPS must be shut down or the load must be transferred to an external maintenance bypass
before a power distribution box may be added, changed or removed.
If the UPS will be shut down, the connected load must be shut down (refer to 4.5 - Shut Down the
GXT4).
If the UPS will be transferred to maintenance bypass, it must be transferred to an external
maintenance bypass. A maintenance bypass in the UPS frame must not be used.
Verify that the Liebert GXT4 is shut down and that all local and remote electric input power has
been disconnected before beginning any work on or in the UPS.
