7. 2 Closing the Sunny Boy
1. Reconnect the earth wire (PE) to the housing cover. Now secure the housing cover
to the Sunny Boy by tightening the four screws evenly. The screws must be tight-
ened with approximately 4 Nm torque in order to guarantee the sealing of the en-
closure.
2. Connect the PV generator. Ensure the assignment of the strings is correct.
3. Check the Electronic Solar Switch for wear as described in chapter 9 "Inspection
of the Electronic Solar Switch" (Page 45).
4. Firmly insert the handle into the socket of the Electronic Solar Switch’s in the bottom
of the Sunny Boy.
5. Switch the line circuit breaker to the "on" position.
6. Now check whether the LED display indicates that the Sunny Boy is functioning cor-
rectly.
Caution!
Follow the sequence below under all circumstances.
Notice!
The Electronic Solar Switch can become damaged if it has not been at-
tached properly.
Firmly insert the handle all the way into the socket in the Sunny Boy and
check that it is firmly inserted. Never tighten the screws of the socket inside
the Sunny Boy in order to avoid that the socket locks in place.
