Restarting the Self-Test

Qualified person

Disconnect the circuit breaker and secure it against reconnection.
If the multifunction relay is used, disconnect the supply voltage to the load.
If an external DC load-break switch is used, switch it off for five minutes and then switch it on again.
If an ESS is in use, pull it out of the inverter for five minutes and then plug it in again firmly.
Recommission the inverter.

The inverter is back in the start-up phase and you can start the self-test once again ( > Starting the Self-Test).
