Earth connection

The APCL earth connections are made by means of a stud (∅ M6). This one is welded inside the APCL in
the lower right corner. The door is already connected to this stud. It only remains to connect the earth wire if
the power cable is fitted with it. For the APCM and APCR, the earth connection can be made by means of
one of the two stud (∅ M8) located in the upper and lower left corners.
