Installation
Checking the Rating Plate
Before you install the VFD, check the rating plate on the side to verify that the voltage, kW (horsepower), and
output current ratings are correct for your application. See Figure 1, Table 1, and
For example, a VFD68DGM would be rated for 575 VAC and 2 horsepower.

IMPORTANT:
Frequently starting and stopping the VFD shortens the lifespan of the VFD68
Drive. In applications where the drive starts or stops frequently, select a VFD that has an output
current rating that is 1.5 to 2 times greater than the FLA current rating of the three-phase motor.
