frequency converter, verify there is a minimum of

100 mm ceiling clearance.

2. Install each M8x60 mm bolt with lock washer and

flat washer through the frame into the threaded

hole in the base. Install 4 bolts per cabinet. Refer

to Illustration 5.30

5.1.6 Lifting

Lift the frequency converter using the dedicated lifting

eyes. For all E2 (IP00) enclosures, use a bar to avoid

bending the lifting holes of the frequency converter.

The following illustrations demonstrate the recommended

lifting methods for the different frame sizes. In addition to

Illustration 5.33, Illustration 5.34, and Illustration 5.35, a

spreader bar is an acceptable way to lift the F-frame.

WARNING

The lifting bar must be able to handle the weight of the

frequency converter. See 5.1.1 Mechanical Dimensions for

the weight of each frame size. Maximum diameter for

the bar is 2.5 cm (1 inch). The angle from the top of the

drive to the lifting cable should be 60

or greater.
