Lifting Instructions for 1397 DC Drives 4
3. Insert properly sized and rated lifting hooks into the top two 1”
holes of the drive chassis (Figure 6). To limit pull in forces on
the drive, the lifting devices connected to the hooks must be long
enough to make the angle between the chain and a vertical line
extending up from the cabinet edge less than 45 degrees as
illustrated in Figure 3.
NOTE: 60 HP and smaller Drives do not have lift holes in the top
of the Drive chassis. If using hooks or lift eyes with these units,
place them in the handholds on the side of the cabinet.
4. Lift drive into place over the top (3) bolts. Verify that the bolt
heads on the panel engage properly into the keyhole slots on the
drive.
5. Once the top bolts are properly seated, the bottom bolts can be
installed and tightened.
6. Tighten all bolts to a torque of 22.6 N-m (200 lb.-in.).
