INSTALLATION
3.1 Mounting Your New Essential Series VFD
Proper installation of the unit is important to the performance and normal operating life of
the unit. It should be installed in a location free from:
• Corrosive gases or liquids
• Excessive vibration
• Airborne metallic particles
Mount the unit to a solid, non-flammable surface capable of bearing the weight using the
mounting bracket provided on the unit.
3.2 Proper Ventilation
In order to maintain air circulation for adequate cooling, minimum clearance around the unit
must be maintained. Allow six inches on each side and top, and 18 inches below.
Ensure air intake and exhaust openings are not obstructed. If the unit is mounted in a small
room, cabinet, or building, ensure there is adequate ventilation to provide sufficient cooling
for the unit.
3.3 Source Branch Circuit Protection
Branch circuit protection must be installed in the circuit sourcing the drive. See Table 2 for
recommended circuit breaker sizing, which is based on 125% of the rated input current.
Fuses may be used for circuit protection; consult local electrical code for proper sizing.
Installation of a disconnection means within sight of the drive is recommended.
