CHAPTER 3: INSTALLATION

3.3.8Current-Only Measurement (Three-Phase)

For this wiring type, select 3 EL WYE (3 Element Wye) in the meter programming setup.

Even if the meter is used only for current measurement, the unit requires a AN volts reference. Please ensure that the voltage input is attached to the meter. AC control power can be used to provide the reference signal.
