1 For alternatives, see section
example of this chapter, the disconnecting device is not in the same cubicle with the drive module.
2 If a shielded cable is used (not required but recommended) and the conductivity of the shield is
< 50% of the conductivity of the phase conductor, use a separate PE cable (2a) or a cable with a
grounding conductor (2b).
3 We recommend 360-degree grounding at the cabinet entry if a shielded cable is used. Ground the
other end of the input cable shield or PE conductor at the distribution board.
4 Input and output power cabling panels (option +H381)
5 We recommend 360-degree grounding at the cabinet entry, see page
6 Use a separate grounding cable if the conductivity of the cable shield is < 50% of the conductivity of
the phase conductor and there is no symmetrically constructed grounding conductor in the cable
(see page 65).
