2. Place two shackles through the spreader bar about 660 mm
(26 in.) apart. Using two wire ropes, hook one end of each rope to
a shackle on the spreader bar. Hook the other end of each rope to
an “S” hook (using a shackle). Perform the appropriate step
below (A or B) for your type of drive.
A. Open Chassis Drive
Insert the “S” hooks into the two top 9.5 mm (0.375 in.) holes
in the drive chassis (A-A). Refer to Figure 1. Proceed to step 3.
B. Drive with NEMA Type 1 Enclosure
Install the two lifting eyebolts (supplied) into the threaded
holes on the top panel of the drive and torque to 9.5 N-m
(7 lb.-ft.). Refer to Figure 1. Insert the “S” hooks into the
eyebolts. Proceed to step 3.
3. Check the hole pattern on the panel to which the drive will be
mounted. Refer to Figure 2 for the correct pattern. Insert, but do
not fully tighten two bolts in the top holes of the panel. Allow
enough room for the drive mounting feet to slide behind the bolt
heads. The bottom bolts will be installed later.
4. Lift drive into place. Verify that the hardware engages properly
into the keyhole slots.
5. Once the top bolts are properly seated, the bottom bolts can be
installed and tightened. Tighten all bolts to a torque of 13.6 N-m
(120 lb.-in.).
The following procedure will guide you through the steps needed to
horizontally mount an open chassis drive through a cutout into a
gasketed NEMA Type 4 or 12 enclosure.
1. Determine the center of gravity for the drive. The hoist hook must
be located directly above the center of gravity to assure that the
drive hangs properly. For example, the center of gravity for a
380-480V, 93 kW (125 HP), 1336 PLUS stand-alone drive is
through the physical center of drive, 330 mm (13 in.) from the
bottom inside flange and about 50.8 mm (2 in.) to the left of
center.
2. Place two shackles through the spreader bar about 660 mm (26
in.) apart. Using two wire ropes, hook one end of each rope to the
same shackle on the spreader bar. Hook the other end of each
rope to an “S” hook (using a shackle). Repeat for second spreader
bar shackle.
Insert two hooks on each side of the drive, using the 9.5 mm
(0.375 in.) holes specified below (refer to Figure 1).
Important: Use holes A-A & C-C for Common Bus Drives.
Use holes B-B & C-C for Stand-Alone Drives.
