1 For alternatives, see section
mounting 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).
3 360-degree grounding is recommended 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 or +H383).
5 360-degree grounding at the cabinet entry is recommended, 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 58).
7 External brake resistor, see page 155.
8 Common mode filter (option +E208), see page 51.
9 du/dt filter (optional, see page 161).
10 The drive module frame must be connected to the cabinet frame. See section
grounding inside the cabinet
Note:
If there is a symmetrically constructed grounding conductor in the motor cable in addition to the
conductive shield, connect the grounding conductor to the grounding terminal at the drive and motor
ends.
Do not use an asymmetrically constructed motor cable. Connecting its fourth conductor at the motor
end increases bearing currents and causes extra wear.
