After testing the residual current circuit breaker, reactivate the Restart device as shown below.
Now run the Restart test:
If the circuit breaker is not automatically switched back on, this means an insulation problem has been detected in the circuit inside
the column, so check the circuit between the residual current circuit breaker and the contactor.
The front door must only be opened to carry out the test on both residual current devices, avoiding contact with any
other accessible device or cable.
