11.3 Acknowledging Error Messages
Once the disturbance is rectified, you can acknowledge the error using the key switch on the inverter or the user interface.

Procedure:
1. If there is an insulation error, switch the insulation monitoring device back on.
2. Turn the key switch to Stop and then back to Start after two seconds.
11.3.2 Acknowledging Errors via the User Interface

11.4 Error Messages
11.4.1 Behavior of the Inverter under Fault Conditions
If a disturbance occurs during inverter operation, this may be due to a warning or error.
Each disturbance has two error levels that influence the display and system behavior. Only a few disturbance types cause
the inverter to behave differently in the two error levels. The error level changes from 1 to 2 if the disturbance occurs five
times within two hours or occurs permanently for two hours.
A warning does not affect the behavior of the inverter. The cause of the warning must be established and remedied.
If operation is interrupted due to an error, the inverter switches to the "Fault" operating state and opens the
AC contactor and the DC switching device. The error, error number, error message and a symbol are displayed on the
touch display (see Section 11.2.1 "Reading Error Messages via Touch Display", page 77).
If the cause of the error is rectified and the error is no longer displayed, the error is deleted from the fault memory.
To view previous errors after they have been deleted from the fault memory, an event file is saved on the SD card.
The time when an error occurred and the type of error are entered in the event file.
You will find the following information in the error tables in Section 11.4.2, 11.4.3 and 11.4.4:
Dealing with disturbances
Error messages should only be acknowledged once the underlying causes have been eliminated.
If the causes of the disturbance have not been eliminated, the disturbance will still be detected after
acknowledgement and the error message will appear again.
