The Ampgard-Drive connection is made by passing hardware
through the Ampgard side sheet (Figure 11) into the
Tinnerman nuts of the transition and requires the use
of 5/16-18 x 2 HHCS, (2) flat washers, lock washer, and
spacer—Eaton PN 25A4184H01, 0.625OD x 0.328ID x 0.85
LGH and torqued to 10–14 ft-lb (Figure 12).

Low voltage connection
Low voltage pathways for drive-to-drive and shipping splits
within a drive are located in the upper front area of the side
sheet (Figure 15).Within the drive, low voltage cables are
routed along the top front of the cabinet (Figure 13) and in
some cases are nested in wireways (Figure 14).
