38 Guidelines for planning the cabinet installation
Planning the layout of the cabinet
Plan a spacious layout to ensure easy installation and maintenance. Sufficient cooling air
flow, obligatory clearances, cables and cable support structures all require space.
Place the control board(s) away from:
• main circuit components such as contactors, switches and power cables
• hot parts (heat sink, air outlet of the drive module).

Air outlet for the drive module and other equipment on the cabinet
roof. An exhaust fan if needed. We recommend this alternative
instead of 2a.
3 Drive control panel with DPMP-03 mounting platform (option
+J410). The control panel is connected to the drive module control
unit inside the cabinet.
4 Contactor control switch and emergency stop switch (connected to
the contactor control circuit inside the cabinet)
5 Operating handle of the disconnector
6 Rubber grommets for degree of protection

Note: The sizes of the air inlet and outlet gratings are critical for
proper cooling of the drive module. For losses and cooling data
requirements, see page 118.
