Replacing the internal cooling fan FSD ... FSF
The PM230 Power Modules have two sets of cooling fans, one fan is internal and the other is
external. The internal cooling fan is mounted inside at the top of the Power Module housing.
The internal cooling fan on the PM230 FSD to FSF is a complete fan modules and require
only a posi-drive screwdriver to remove and replace the fan module. The power connection
on the fan module is an integral part of the fan module and does not require separate
removal.
Preparatory steps

● Remove any external power to the Control Unit
● Allow at least 5 minutes for the Power Module to completely discharge.
● Open the enclosure door.

3. Unhook the fan module from the fan module housing (indicated in the figure below as
