3.1.2 Drive Module Fan Replacement
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 Baldor. Do
not use other than Baldor specified spare parts.
Refer to the installation instructions supplied with the fan kit.
3.1.3 Enclosure Fan Replacement – UL Type / NEMA 12 Floor Mount Enclosures
UL Type 12 / NEMA 12 enclosures include an additional fan (or fans) to move air through the enclosure.
