Event number Message, cause and corrective measures
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17 "Contact",
page91).
801
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:
• Make sure that the circuit breaker is switched on.
• Ensure that the AC cable is not damaged and that it is connected
correctly.
• Ensure that the country data set has been configured correctly.
• Check whether the grid voltage at the connection point of the inverter is
permanently in the permissible range.
If the grid voltage is outside the permissible range due to local grid
conditions, contact the grid operator. The grid operator must agree with
an adjustment of the voltage at the feed-in point or with a change of the
monitored operating limits.
If the grid voltage is permanently within the permissible range and this
message is still displayed, contact the Service (see Section17 "Contact",
page91).
901
PE conn. missing > Check connection
The grounding conductor is not correctly connected.
Corrective measures:
• Ensure that the grounding conductor is correctly connected (see
Section6.3.2, page27).
