Installation of the Drive in the Enclosure
Mount the drive in the enclosure using UL Type 3R
mounting provisions if the UL Listing is to be main-
tained. The drive mounting hardware is not included in
this kit.
Note that 41 and 42 frame drives should be mounted
in a welded enclosure with a minimum back wall thick-
ness of 12ga. (2.7mm). 51 frame drives should be
mounted in a welded enclosure with a minimum back
wall thickness of 10 ga. (3.4mm). Brace the back wall
of the enclosure appropriately to support the drive.
Drawings 175R1069 will assist in determining the drive
mounting locations, air intake and outlet opening loca-
tions, and mounting hole locations on the outside of
the enclosure. There are separate pages in the draw-
ing for 41, 42 and 51 frame drives.
After drive attachment points and hole locations are
determined, cut all openings and install drive mounting
hardware. See Figure 7.
Install gasket material around the vent openings on the
inside and outside of the enclosure. See Figure 8.
