The appropriate Volts Mode setting is included with each wiring diagram.
Refer to Step 7 to learn how to configure Volts Mode on the meter.
CT & PT Selection
Consult your local instrument transformer expert, either at the local utility or
through a vendor or supplier, to obtain CT and PT selection standards for
high accuracy revenue metering applications in your regions.
