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
1. Disconnect the miniature circuit-breaker and secure against reconnection.
2. If the multi-function relay is used, switch off the load supply voltage.
3. Remove the ESS from the inverter for five minutes and then plug it in again firmly.
4. Restart the inverter
☑ The inverter is now back in the start-up phase and you can start the self-test
(see Section 7.3.1).
7.4 Deactivating Protective Conductor Monitoring
If the inverter is to be installed in an IT system or other earthing system for which it is advisable to
deactivate the protective conductor monitoring, deactivate it by means of a communication product
as described in this section (for information on the setting of operating parameters, see respective
communication product manual).
Requirements:
• A communication product that is appropriate for the type of communication used must be
available.
1. Log in to the communication product as an Installer.
2. Set the parameter PE monitoring or PEOpnMon to Aus or Off.
3. Save setting.
