5.6 Cooling Fan Kit
When using more than one power supply in the PN Series Enclosures, a cooling fan is
required. The Cooling Fan kit includes an intake fi lter, located inside the front door of the
enclosure by the ventilation louvers. The fi lter must be cleaned periodically as part of the
power supply preventative maintenance program.
Replacement fuses and fi lters are available. Refer to Section 6.0 for part numbers.

CAUTION!
The input voltage of the AutoTransformer must match the output voltage of the power supply.
Incorrect input voltage can cause the transformer to overheat and fail, or underpower the fans
resulting in degraded cooling performance.
