Check that the energy meter is correctly connected to the CT (current transformer) before setting up the energy meter.

  • The white wire / S1 of the transformer must be connected to the + terminal of the energy meter.

  • The black wire / S2 of the transformer must be connected to the – terminal of the energy meter.

Attention!

If connected incorrectly, there is a possibility that the current will be measured incorrectly. For example, when you connect the black wire to the positive terminal of the energy meter.
