Event number Display message, cause and corrective measures
501 Grid fault
The power frequency is not within the permissible range. The inverter has dis-
connected from the utility grid.
Corrective measures:
• If possible, check the power frequency and observe how often
fluctuations occur.
If fluctuations occur frequently and this message is displayed often,
contact the grid operator and request approval to change the operating
parameters of the inverter.
If the grid operator gives his approval, discuss any changes to the
operating parameters with Service (see Section 15, page 43).
601 Grid fault
The inverter has detected an excessively high proportion of direct current in
the grid current.
Corrective measures:
• Check the grid connection for direct current.
• If this message is displayed frequently, contact the grid operator and
check whether the monitoring threshold on the inverter can be raised.
701 Frq. not permitted > Check parameter
The power frequency is not within the permissible range. The inverter has dis-
connected from the utility grid.
Corrective measures:
• If possible, check the power frequency and observe how often
fluctuations occur.
If fluctuations occur frequently and this message is displayed often,
contact the grid operator and request approval to change the operating
parameters of the inverter.
If the grid operator gives his approval, discuss any changes to the
operating parameters with Service (see Section 15, page 43).
1302 Waiting for grid voltage > Grid failure > Check AC circuit breaker
The AC cable is not correctly connected or the country data set is not correctly
configured.
Corrective measures:
• Ensure that the AC cable is correctly connected (see the operating
manual of the inverter).
• Ensure that the country data set has been configured correctly.
• Check the fuse.
