Guidelines for planning the cabinet installation 43
• We recommend 360° high frequency grounding of the motor cable shields at their
entries. The grounding can be implemented by a knitted wire mesh screening as
shown below.
• We recommend 360° high frequency grounding of the control cable shields at their
entries. The shields can be grounded by means of conductive shielding cushions
pressed against the cable shield from both directions as shown below:
1 Cable
2 Cable tie
3 Strain relief
4 Bare cable shield
5 Knitted wire mesh
