5.4 Wiring test
If the wiring is incorrect and the device detects an energy flow in the wrong direction, the
message Err 3 appears on the display.
This error is either caused by incorrect wiring of the current inputs (terminals L ↑ and L ↓) or
by incorrect voltage wiring (terminals N - L ↑).
Energy is not counted under these conditions.
