REGULAR INSPECTION B-5
4. CLEANING THE ELECTRICAL CABINET AIR FILTER
The electrical cabinet is not cooled directly by outside air; it is cooled indirectly through heat
exchange between outside air, taken into the cabinet through the duct, and inside air.
Therefore, if the air filter at the air suction port is clogged, the inside of the electrical cabinet will
not be cooled satisfactorily.
