Remove the Main AC or DC Fan Power Supply Assemblies
You must remove the main fan power supply assemblies from the drive in order to
replace the AC or DC fan power supply circuit board, AC fan inverter output
transformer, and AC fan inverter capacitor. Follow these steps to remove the
main fan power supply assemblies.
Note: If you are replacing only one fan power supply assembly, only complete the
steps for the side of the drive that contains that assembly. When replacing a failed
AC fan system with a DC fan system, remove and replace both AC fan systems.
