8.2 Closing the Sunny Boy
1. Connect the DC plug connectors.
Check that the polarity is correct and ensure that
the strings are assigned correctly (as described in
section 6.3 „Connection of the Solar Generator
(DC)” (Page 33)).
2. Close the lid with six screws.
Tighten the screws in the sequence shown on the
right to a torque of 1.4 Nm.
3. Check the Electronic Solar Switch for wear as
described in section 9.2 and connect it after
successful testing.
DANGER!
Risk of lethal electric shock!
A hazardous electric arc can form if the DC plug connector is removed without first
removing the Electronic Solar Switch.
• Do not plug in the Electronic Solar Switch until the lid is closed.
• Operate the Sunny Boy only when the lid is closed so that the DC plug
connectors cannot simply be removed.
