- Batteries are full? Solution: No action necessary.
- Input fuse generator on MobilHybrid dropped? Solution: Search for the error, eliminate it and restart.
- Insulation monitor has detected insulation fault? Solution: Search for the error, eliminate it and restart.
- Wrong rotating field of the supply line? Solution: Have it checked by a qualified electrician and changed to clockwise rotation.
