Planning the cabinet installation

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 117
and 122. 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.
• The cabinet must have enough free space for the components to ensure sufficient
cooling. Observe the minimum clearances given for each component. For the
required free space around the drive module, see page 43.
• The heat dissipated by cables and other additional equipment must also be
ventilated.
• The air inlets and outlets must be equipped with gratings that:
• guide the air flow
• protect against contact
• prevent water splashes from entering the cabinet.
