X29 + protective ground at middle screw operating unit cover
Heating plate
The ring eyelet of the protective ground at line 0 is attached with sprockets and an additional nut at the middle attach-
ment screw of the operating unit cover.
Caution: This connection creates the safety-technically important contact between the housing parts and the protec-
tive ground. Always observe the position of the washers and sprockets:
Housing > sprocket > ring eyelet > sprocket > washer > nut M (see image section)
Route the lines cleanly with small cable ties (99 mm) and a self-adhesive cable tie holder and secure them.
The lines must not get into the rotating toothed belts in operation.
