2. Loosen, but do not remove, the six hexalobular screws that secure the top
air flow plate to the drive, and slide the plate forward to lift it off the
screws. The tightening torque is noted in the illustration for reassembly.
Step 3: Remove the Existing
Fan Assembly
1. Remove the wires that are connected to the terminal block at XF on the
fan loss detection circuit board (located at the top of the drive, to the left
of the fan blower).
IMPORTANT
The air flow plate cannot be removed from the drive unless the AC input wiring
and bus bar extensions (if installed) are removed. However, the plate must be
removed to remove the fan assembly bracket below it.
