3.3.7 Configuration for 480V 4-Wire WYE Synchro/Power
Control Connection
The following shows a typical hardware configuration for a 3-phase, 4-wire WYE power
paralleling/synchronizing application. The offset and gain values are shown at their default
values. For maximum accuracy, the offset and gain values must be set, based on the
IC694PSM001 module faceplate label and on the IC694ACC200 terminal assembly label
calibration constants. Choose the 600V range and enter 480.0V as the nominal voltage. The
Nominal Voltage is the anticipated Phase-to-Neutral voltage in the WYE configuration.
