VFD700 AC Drive Getting Started Guide 27
NOTE:
To know how to choose fuse and switch please refer to table 2-14.
When the contactor is used in power supply control ,it is not suggested to use the power
contactor to control the drive to RUN/STOP .
Under default carrier frequency, the maximum motor cable length is 100 meters.When
the motor cable is longer than 100m, output reactor is suggested to use.
For the sake of safety, the drive and motor must be earthed, and the earth resistance must
be less than 10Ω, and the cross-sectional area of earth conductor must meet the
requirements in table 2-15.
