Event 3908
Qualified person
Event message:
Leakage current-carrying capacity of DC generator too high.
Explanation:
The permissible residual current reaches or exceeds the threshold.
Corrective measures:
If a residual-current device is installed, ensure that it is set correctly.
Observe the behavior of the inverter and wait to see whether the inverter resumes operation on its own.
Ensure that no insulation error is present and that the residual-current device is functional.
