Additional grounding of the housing
If a second protective earth connection is required in the installation country (e.g. Switzerland), you
can also ground the Sunny Boy with an additional protective earth on the connection terminal of the
housing.
Proceed as follows:
1. Loosen screw (A) halfway.
2. Insert the stripped grounding cable (D) under the
terminal clamp (max. cross section: 16 mm²).
3. Screw the terminal (C) tight.
The toothing of the washer (B) must face toward
the terminal clamp.
You can ground multiple Sunny Boys as shown below:
NOTICE!
High leakage currents can damage the Sunny Boy!
• Do not ground any modules on the terminal for ground connection cables in the
Sunny Boy.
