The line conductor L1 supplies power to the Energy Meter. At least
the line conductor L1 and the neutral conductor must be connected
to the Energy Meter.
Just connect the line conductors L1, L1’ and the neutral conductor,
then the three-phase Energy Meter can be used as a single-phase
Energy Meter.
For Single-phase Energy Meter
1. Take out the Energy Meter (with 1-phase sensor) and the cables from the
