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 122 °F
(-25 °C to 50°C).
The drive electronics are air-cooled. Allow at least 6 inches (15.24 cm) of clearance
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 to maintain the NEMA 3R rating.
•
Mount the unit vertically with the wiring end oriented downward, and properly
secure the cover (also applies to indoor installations).
•
Protect from hose-directed or sprayed water as well as blowing rain. NEMA 3R
enclosures are capable of withstanding downward-directed rain only. Failure to do so may result in drive failure.
•
Install away from direct sunlight or locations subject to extreme temperatures or humidity.
•
Use appropriate screening for the air inlet and outlet when installed in areas where insect or small animal intrusion is an is-
sue. Refer to
"Accessories" on page 59
•
Clean screens on a regular basis to ensure proper airflow.
