5 Connect the protective earth (PE) of the

mains cable to the right terminal of the

terminal block (see figure to the right).

To do this, the PE wire must be 5 mm longer

than the L and N wires!

If a second protective earth connection is required, you can use

the additional connection terminal directly on the Sunny Mini

Central's housing for this purpose.

Proceed as follows:

1. Insert the terminal clamp in the slits and

screw the terminal half tight with the

supplied M6x16 screw and washer.

The toothing of the washer must face

toward the terminal clamp.

2. Insert the stripped grounding cable.

3. Secure the terminal tightly.

6 Connect the mains cable as shown in the

figure. Use the supplied cable feed-through.

"L" and "N" must not be swapped!
