ONSIDERATIONS
The SSPA is cooled by forced air. The cooling fan is configured for 48V DC operation.
Depending on environmental conditions, the air inlet or outlet openings may become obstructed
by debris, reducing the efficiency of the cooling system. Inspect the unit periodically to ensure
that the grill of the fan intake and all openings on the unit are free of any obstructions.
Insufficient cooling will significantly impact SSPA longevity.
