6.3 Connect Input/Output Power
The UPS has hardwire terminal blocks for input and output electrical connections. Optional output
distribution modules permit connecting additional loads to the UPS. These optional plug-and-play
distribution modules offer different types and numbers of connection plugs.
6.3.1 Distribution Module Electrical Connections
Electrical connections are made through a removable conduit box that attaches to the rear of the
UPS.
The installer must provide a 60A branch circuit breaker. The input circuit breaker and the output cir-
cuit breaker on the rear fixed-panel of the UPS disconnect all power between the main cabinet and
the distribution box.
The manual bypass switch passes utility power directly to the bypass switch from the input terminal
block. The input circuit breaker does not disconnect power from the manual bypass switch.

connections.
