Procedure once the power distribution grid becomes available again

again once the load has been disconnected and the miniature circuit-breaker is switched back on.
1. Disconnect the load.
2. Remove the plug for the load from the secure power socket-outlet.
3. Switch off the secure power socket-outlet so that the inverter begins feeding into the power
distribution grid again.
4. Switch the inverter miniature circuit-breaker back on.
