Planning the cabinet installation 37
Planning the grounding of the cable shields at the cabinet
lead-through
Follow the principle shown in the figure 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:
•
The installation site must be sufficiently ventilated so that the cooling air flow and
ambient temperature requirements of the drive module are met, see pages
112 and
116 . 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.
