Connecting Input Plug and Loads

NOTE
Ensure that all the loads are turned Off.
Prepare an input power supply that is properly protected by a circuit breaker in accordance
with national and local electrical codes. The wall receptacle must be grounded.
The plug on the power supply cord is intended to serve as the disconnect device. The
socket-outlet must be installed near the equipment and must be easily accessible.
Emerson recommends installing an upstream circuit breaker of the same series as the Liebert
GXT3's input circuit breaker.
The specification of input circuit breaker on the rear panel of UPS is given in Table 2.
