IT guard triggered

Carry out insulation test according to operating instructions if IT network. If the test does not run as described, please switch off the MobilHybrid immediately (press the emergency stop button) and inform a qualified electrician who will identify and rectify the fault. The MobilHybrid must not be used again until the fault has been rectified and the insulation monitor is ready for operation! The same applies if the insulation monitor trips during operation and indicates an insulation fault (yellow LED lights up).
