Fig.4-8: 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 delivers the air
into the control cabinet and generates overpressure in the control cabinet.
This overpressure prevents unclean air from entering into the control cabinet
through potentially leaky points (leaky cable passages, damaged seals, etc.).
