Configuration for 120/240 VAC Single Phase System
Grid 1 or Grid 2 Tab
3-26
The following shows a typical hardware configuration for a signal phase, 3-wire power
monitoring application. This example shows settings for Grid 1; all the settings can be
applied to the respective Grid 2 parameters. Note that the offset and gain values were
found on the IC694PSM001 module faceplate label and on the IC694ACC200 terminal
assembly label. Note that the 120V range will accurately measure voltages slightly above
120VAC RMS. In the example below, 125VAC RMS is chosen as the nominal voltage.
The Nominal Voltage is the anticipated Phase-to-Neutral voltage in the single phase
configuration.
