Lifting PowerFlex DC Drives
The dimensions and weights specified above must be taken into consideration
when mounting the device. Use the proper equipment to safely lift and hold the
weight of the drive while mounting.
Mounting Frame C and D Drives
All lifting equipment and lifting components (hooks, bolts, lifts, slings, chains,
etc.) must have a minimum
lifting capacity of 453.6 kg (1,000 lb).
1. Verify the hole pattern on the panel to which the drive will be mounted.
See Figure 4
on page 21 or 22 on page 22.
2. Install the mounting hardware:
❏ For frame C drives, insert, but do not tighten, a bolt in one of the top
holes in the panel. The bolt must be fully threaded into the panel
before hanging the drive.
❏ For Frame D drives, insert, but do not tighten, the six bolts for the top
mounting flange on the drive into the panel. The bolts must be fully
threaded into the panel before hanging the drive.
3. To limit the pull in forces on the drive, the lifting devices connected to the
hooks must be long enough to make the angle between the chain or cable
and a vertical line extending up from the flange center less than 45° angle as
illustrated in Figure 7
on page 26 or Figure 8 on page 27.
❏ For frame C drives, insert the properly sized and rated lifting hooks
into the holes on the lifting flanges at the top of the drive. See Figure 7
on page 26
.
❏ For frame D drives, insert the properly sized lifting rod into the holes
on the lifting flanges at the top of the drive. See Figure 8
on page 27.
ATTENTION: To guard against possible personal injury or equipment damage...
• Inspect all lifting hardware for proper attachment before lifting the drive.
• Do Not allow any part of the drive or lifting mechanism to make contact with
electrically charged conductors or components.
• Do Not subject the drive to high rates of acceleration or deceleration while
transporting to the mounting location or when lifting.
• Do Not allow personnel or their limbs directly underneath the drive when it is
being lifted and mounted.
Verify that all mounting screws are properly tightened before and after drive
operation.
