Emerson GXT2-10000RT208 Connect Input/Output Power, Distribution Module Electrical Connections

Installation and Configuration

6.3Connect 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.

! WARNING

The UPS must be completely powered down before beginning to make these electrical connections.

6.3.1Distribution 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.
