ONSIDERATIONS
The SSPB is forced-air cooled. The cooling fan is configured for 220 VAC operation, supplied
by the
main power supply of the unit via a speed controller. Depending on environmental
co
nditions, the airflow opening may become obstructed by debris, reducing the efficiency of the
cooling system.
NOTE:
The cooling fan rotation speed is temperature dependent.
In
spect the unit periodically to ensure that the grill of the fan intake and all openings on the unit
are free of any obstructions. Insufficient air-cooling will significantly impact upon the SSPB
lon
gevity.
