ABB G3EFa HENF450295R2 Transfer switch module

Phase rotation sequence need not be observed when connecting the power lines to the input terminals of the power supply. A neutral connection (marked N) is required for the 380, 400, 415 and 480 VAC rated units. For safety, the chassis ground terminal should be connected to earth ground. The input wires must be of the proper gauge size to minimize impedance. The wiring of the AC input connector is dependent upon the rated input voltage of the power supply. Refer to the below table for the appropriate connections.Both POS and NEG output terminals are floating (not connected to ground). Either may be grounded or operated at any voltage less than 600 VDC with respect to chassis ground.

RSTL Controller Board:

This is an optional board that can be installed at the customer's request. The board is designed for remote computer control, functionally duplicating the controls on the front panel of the power supply. These controls select the programming levels (Voltage and Current), and provide metering of the supply's output. The RSTL, when set in the REMOTE mode, disables the front panel control pots (but the meters still read), and asserts control of the power supply. For detailed information, refer to Section 4.
