Options
11.7 Monitoring functions
If a second fault occurs, protective separation cannot be ensured in all cases.
As a consequence, as soon as the first fault is detected by the insulation monitor, the
converter system must be brought to a safe state if a second ground fault cannot be ruled
out.
The system is not permitted to be switched on again until the ground fault has been
eliminated.
