The connection between the PE conductor screw (figure4-8, item 5, page128) to ground must be established addition-
ally for high electromagnetic compatibility (EMC) in 115/230 V-controllers.
This connection must also be low resistive for high frequencies (Cu-band or Hf-strand). Alternatively at least 2.5 mm
2
flexible should be used.
