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
JCI
. Do not use other than
JCI
specified spare parts.
To monitor the running time of the cooling fan, see
