Event message:
Grid overvoltage
Explanation:
The grid voltage is higher than the set conservation value.
Corrective measures:
Wait until the grid voltage is within the normal range again.
If the error occurs repeatedly, measure the present grid voltage and contact the local grid operator concerning solutions if the supply grid voltage is higher than the set value.
Ensure that the protection parameters are set correctly.
Ensure that the cross section of the alternating current cable meets the requirements.
If the fault cannot be rectified using the indicated corrective measures, contact Service.
