corrosive gases, ensure that the IP/Type rating of the
equipment matches the installation environment. Failure
to meet requirements for ambient conditions can reduce
lifetime of the frequency converter. Ensure that
requirements for air humidity, temperature, and altitude
are met.
Vibration and shock
The frequency converter complies with requirements for
units mounted on the walls and floors of production
premises, and in panels bolted to walls or floors.
For detailed ambient conditions specifications, refer to

3.3 Mounting

NOTICE
Improper mounting can result in overheating and
reduced performance.
Cooling
•
Ensure 100 mm (3.9 in) of top and bottom
clearance for air cooling.
Lifting
•
To determine a safe lifting method, check the
weight of the unit, see chapter 9.9 Enclosure Sizes,
Power Ratings, 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.

Mounting
To adapt the mounting holes of VLT
contact the local Danfoss supplier to order a separate
backplate.

enough to support the unit weight. The
frequency converter allows side-by-side instal-
lation.
