For lifting, use hoist rings on the unit, when
provided
Figure 2.6 Recommended Lifting Method, 4X and 5X Unit Sizes.
WARNING
The lifting bar must be able to handle the weight of the
adjustable frequency drive. See
Mechanical Dimensions
for
the weight of the different unit sizes. Maximum diameter
for bar is 1 in [2.5 cm]. The angle from the top of the
adjustable frequency drive to the lifting cable should be
60
°
or greater.
2.3.4 Mounting
•
Mount the unit vertically
•
The adjustable frequency drive allows side by
side installation
•
Ensure that the strength of the mounting location
will support the unit weight
