Passive cabinet ventilation

The differences between ambient temperature and the temperature inside a cabinet with a high protection rating may
generate variations in pressure. In the event of under-pressure, the cabinet may draw in dust and moisture. Any moisture
trapped inside the cabinet will be deposited as condensation. This condensation can be prevented through the use of
ventilation grilles.
