Danfoss VLT HVAC Design Guide

5.1.5 Lifting
Always lift the frequency converter in the dedicated lifting eyes. For all D and E2 (IP00) enclosures, use a bar to avoid bending the lifting holes of the
frequency converter.
Illustration 5.3: Recommended lifting method, frame sizes D and E .
The lifting bar must be able to handle the weight of the frequency converter. See Mechanical Dimensions for the weight of the different
frame sizes. Maximum diameter for bar is 2.5 cm (1 inch). The angle from the top of the drive to the lifting cable should be 60° C or
greater.
