2. Tap on the display within 20 seconds and enter the test results into the test report as they
appear.
☑ The self-test starts.
☑ The inverter displays the results of the individual tests for overvoltage, undervoltage,
maximum frequency and minimum frequency. The results are displayed three times in
succession for ten seconds each.
7.3.2 Abortion of the Self-Test
If, during the self-test, an unexpected disconnection requirement occurs, the self-test is aborted.
The same applies if the DC voltage is so low that feed-in cannot be continued.
• A message informing you that the self-test has been aborted is shown in the display for ten
seconds: Autotest interroto.
• Restart the self-test (see Section 7.3.3).
7.3.3 Restarting the Self-Test
In order to restart the self-test, proceed as follows:
1. Disconnect the miniature circuit-breaker and secure against reconnection.
2. If a multi-function relay is connected, disconnect its supply voltage.
3. Remove the ESS from the inverter for five minutes and then plug it in again firmly.
4. Recommission the inverter (see Section7 "Commissioning", page57).
☑ The inverter is now back in the start-up phase and you can start the self-test (see Section 7.3.1).
