5.4.2 Distribution Box Electrical Connections
Electrical connections are made through a removable power distribution box that attaches to the rear
of the UPS.
The installer must provide a 30A branch circuit breaker, with NEMA L6-30R receptacle. The Input
circuit breaker on the distribution box and the Output circuit breaker on the rear fixed-panel of the
UPS disconnect all power between the main cabinet and the distribution box.
Models equipped with a manual bypass switch pass bypass power directly to the bypass switch from
the input power cord. The input circuit breaker on the distribution box does not disconnect power
from the manual bypass switch.
