Phase wire short-circuited to PE

What does 2031 mean?

The impedance of the output phase wire to PE (Protective Earth) is low or the output phase wire is short-circuited to PE. This is a serious electrical safety fault indicating a direct connection between a phase conductor and ground.

• The impedance of the output phase wire to PE is low or the output phase wire is short-circuited to PE.
