Lifting
•
To determine a safe lifting method, check the
weight of the unit, see chapter 8.9 Power Ratings,
Weight and Dimensions.
•
Ensure that the lifting device is suitable for the
task.
•
If necessary, plan for a hoist, crane, or forklift with
the appropriate rating to move the unit.
•
For lifting, use hoist rings on the unit, when
provided.
Mounting
1. Ensure that the strength of the mounting location
supports the unit weight. The adjustable
frequency drive allows side-by-side installation.
2. Locate the unit as near to the motor as possible.
Keep the motor cables as short as possible.
3. Mount the unit vertically on a solid flat surface or
on the optional backplate.
4. Use the slotted mounting holes on the unit for
wall mounting, when provided.
