NOTE
In 4LN3 and 3LN3 wiring modes, the voltage readings for volt demands represent line-to-neutral
voltages; otherwise, they will be line-to-line voltages. The voltage waveforms and harmonics in
4LN3 and 3LN3 wiring modes represent line-to-neutral voltages; otherwise, they will be line-to-line
voltages
