Planning the grounding of the cable shields at the cabinet lead-through
Follow the principle shown below when planning the grounding of the cable shields
at the cabinet lead-through.
Planning the cooling
Note following guidelines when planning the cooling of the cabinet:
• Ventilate the installation site sufficiently so that the cooling air flow and ambient
temperature requirements of the drive module are met, see pages 129 and 134.
The internal cooling fan of the drive module rotates at a constant speed thus
blowing constant air flow through the module. Whether the same amount of air
must be replaced all the time in the facility depends on how much heat must be
removed.
Example cable lead-through
1 To power cable terminals
2 Cable shield
3 PE (ground) terminal of the cabinet, cabling panel or
drive module
4 Stripped part of the cable
5 EMC sleeve
6 Lead-through plate
7 Base plate
8 Strain relief
9 Conductive shielding cushions for control cables
