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 “
Electrical Installa-
tion” on page 3.
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.
