b) Use a thin permanent marker to mark the locations where the new
mounting screws will hold the new VFD in place. Remove the VFD from
the enclosure.
c) Remove the old mounting screws. Discard the four old mounting screws.
Keep the washers.
d) Drill in the four places indicated by your marks on the rear wall of the
enclosure using a #21 bit. Tap the holes using the #10-32 tap.
If you have an ACS880 VFD using 415V or
460V power, your VFD is physically smaller
than the old one. You need to drill.
Continue to step 1 below this notice.
If you have an ACS880 VFD using 208V or
230 V power, your VFD is the same size as
the old one. Remove the old mounting
screws. Mount the new VFD using the new
mounting screws and old washers. Then
skip to step 1 on page 12.
