Earth (ground) fault

What does 14 mean?

There is an undesirable current path from one or more output phases to earth, either in the cable connecting the frequency converter to the motor or within the motor itself. This fault indicates a serious insulation breakdown, posing a safety risk and potential for severe equipment damage if power is not immediately removed.
