WARNING
HEAVY LOAD
Unbalanced loads can fall and loads can tip over. Failure
to take proper lifting precautions increases risk of death,
serious injury, or equipment damage.
•
Never walk under suspended loads.
•
To guard against injury, wear personal
protective equipment such as gloves, safety
glasses, and safety shoes.
•
Be sure to use lifting devices with the
appropriate weight rating. To determine a safe
lifting method, check the weight of the unit, see
chapter 8.9 Power Ratings, Weight, and
Dimensions.
•
The angle from the top of the drive module to
the lifting cables has an impact on the
maximum load force on the cable. This angle
must be 65° or greater. Attach and dimension
the lifting cables properly.
Mounting
1. Ensure that the strength of the mounting location
supports the unit weight. The frequency
converter 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 to a solid flat surface or
to the optional backplate to provide cooling
airflow.
4. Use the slotted mounting holes on the unit for
wall mount, when provided.
Mounting with mounting plate and railings
A mounting plate is required when mounted on railings.
