1.2.8 Ventilation Requirements: The Rectifiers are fan cooled and utilize front to back forced
ventilation. The Power/Distribution Bays and Power Only Bay must be mounted so ventilating
openings are not blocked and temperature of the air entering the Rectifier shelf does not
exceed the Operating Ambient Temperature Range stated above.
Also, the distance from the rear of a Power/Distribution Bay or Power Only Bay to a wall or
other solid structure must not be less than 6 inches. This will assure proper air flow through
the Rectifiers.
