    Drive Module Fan Replacement

    Refer to the installation instructions supplied with the fan kit. Enclosure fan replacement – UL Type 12 enclosures UL type 12 enclosures include an additional fan (or fans) to move air through the enclosure.

    The drive module fan cools the heatsink. Fan failure can be predicted by the increasing noise from fan bearings and the gradual rise in the heatsink temperature in spite of heatsink cleaning. If the drive is operated in a critical part of a process, fan replacement is recommended once these symptoms start appearing. Replacement fans are available from Daikin. Do not use other than Daikin specified spare parts.
