NOTICE
Risk of damage to VFD, or malfunction can occur due to improper handling, in-
stallation, or environment.
•
Do not mount VFD on equipment with excessive vibration.
•
Install in a location where temperature is within the range of product rating.
•
Mount VFD vertically (top up) for proper heat dissipation.
•
Do not mount VFD in direct sunlight or near other heat sources.
•
Do not install in corrosive environments.
•
Install at least 18" (45.7 cm) above the ground.
•
Installation of non-approved screening may damage the drive and/or reduce output.
The drive is intended for operation in ambient temperatures from -13 °F to 104 °F
(-25 °C to 40 °C). Use the following recommendations when selecting a location to
mount the drive:
•
The drive electronics are air-cooled. Allow at least 6 inches (15.24 cm) of clear-
ance around the unit for air flow.

The drive is suitable for outdoor use with a NEMA 3R rating; however, the following
considerations should be made for outdoor installations:
•
Mount the drive on a wall or back plate that is at least 6 inches (15.24 cm) larg-
er than the outer dimensions of the enclosure in order to maintain the NEMA
3R rating.
•
The unit must be mounted vertically with the wiring end oriented downward,
and the cover must be properly secured (also applies to indoor installations).
•
NEMA 3R enclosures are capable of withstanding downward-directed rain only.
Protect from hose-directed or sprayed water as well as blowing rain. Failure to
do so may result in drive failure.
•
Install away from direct sunlight or locations subject to extreme temperatures or humidity.
