Rotating the Drive About the Board
Figure 2.6 shows the drive, with the lifting feet attached, on a skid. To avoid
damage to the drive input terminals when lifting the drive to a vertical
position, do the following.
1. After the straps are in place (see Applying Strap Angles on page 2-5 ),
carefully lift the drive to rotate it 90° to a vertical position.
2. Remove the lifting feet before installing the drive into the enclosure.

Mounting Requirements The PowerFlex700L Frame 2 drive is a single integrated assembly
consisting of a filter section and a power section. The filter section provides
the mounting feet and represents greater than 50% of the approximate 186
kg (410 lb) total weight. Follow these mounting requirement guidelines.
1. Mount the Frame 2 drive into an enclosure that is designed according to
Electrical Equipment Pollution Degree 2 requirements.
2. Size and fasten any enclosure mounting panel appropriately to
accommodate for the weight of the drive.
3. The Frame 2 drive is designed to use eight M8 x 1.25 fasteners in
mounting slots shown in Detail A and Detail B of Figure 2.1 .
4. The M8 x 1.25 fasteners must be class 5.8 or greater.
5. Use a lock washer or similar mechanism to prevent the fasteners from
loosening after mounting.
6. All M8 x 1.25 fastener threads must engage a steel panel with 6 to 7 full
threads or a permanent backing nut such as a weld nut or a
self-clinching PEM
® (1)
nut with 4 full threads.
7. Tighten the M8 x 1.25 fasteners to 11.3 ± 2.8 N •m (100 ± 25 lb•in)
unless the lock washer mechanism requires a different torque. If this is
the case, the holding force must be equivalent.
