Fig. 4-1: Control cabinet ventilation (schematic diagram)
Only clean air gets into the control cabinet through the filter at the air intake
opening. The control cabinet fan behind the air intake opening conveys the
air into the control cabinet and generates overpressure in the control cabinet.
The overpressure prevents unclean air from getting into the control cabinet
through possibly existing leaky points (leaky cable ducts, damaged seals,
etc.).
