F0510min Overvoltage
Name in the manufacturer's documentation (user manual): 10min Overvoltage
[1]
In plain words (editorial)
The 10-minute average of the grid voltage is above the limit set by the safety regulations – the grid has been running at a relatively high voltage for a long time.
When to call a service technician: If it happens frequently, contact your installer – the grid values may need to be checked with the local power operator; protection settings are changed only with the operator's approval.
