Fig. 17: Only the nut (1) and the washers (2), (3) may be loosened for mounting the grounding
cable (PE).
The grounding cable has to be furnished with a ring-terminal, that gets fastened between
two washers, see the blue “PE” marking in the image above.
First you have to remove the nut (1), the serrated lock washer (2) and the upper washer (3),
then mount the eye of the ring-terminal, nally fasten the nut and washers again (tightening
torque: 1.6 Nm [14.2 lb⋅in]).
The lower parts that are marked with the red (!) in the image must be kept xed all
the time!
