Physical Installation
Environmental Requirements
The drive is intended for operation in ambient temperatures from -13 °F to 122 °F (-25 °C to 50 °C). Use the
following recommendations when selecting a location to mount the drive:
•
The drive should be mounted on a structure such as a wall or post
capable of supporting the weight of the unit, at least 18” (45.7 cm) off
the ground.
•
The drive electronics are air-cooled. Allow at least 6 inches (15.24 cm)
of clearance on each side and below the unit for air flow.
•
The mounting location should have nearby access to an appropriate
electrical supply and to the motor wiring. Refer to
Special Considerations for Outdoor Use
The drive is suitable for outdoor use with a NEMA 3R rating; however, the
following considerations should be made for outdoor installations:
•
The unit must be mounted vertically with the wiring end oriented
downward, and the cover must be properly secured (also applies to
indoor installations).
•
Mount the drive on a back plate 6” (15.cm) larger than the outer
dimensions of the enclosure in order to maintain the NEMA 3R rating.
•
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 controller failure.
•
Install away from direct sunlight or locations subject to extreme temperatures or humidity.
Pressure Tank Sizing
A VFD system needs only a small pressure tank to maintain constant pressure, although a larger tank may
be used. The pressure tank pre-charge setting should be 70% of the targeted system pressure.
Risk of damage to drive
,
or malfunction can occur due to improper handling,
installation, or environment.
•
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.
•
Installation of non-approved screening may damage the drive and/or reduce output.
