32 Planning the cabinet installation
Planning the layout of the cabinet
Design 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:
•
the main circuit components such as contactor, switches and power cables
•
hot parts (heat sink, air outlet of the drive module).
