g. Always insure that VLT can handle maximum current of the motor.
It is important to check the technical data of the instruction manual for the drive you
are installing to certify that the VLT is able to handle the maximum FLA of the
motor.
Example: a 100Hp (75kW) motor has a FLA of 125amps at 460Vac. The technical
data using the High Overload (150%) section and 460 V and VLT,N rating equals
130amp, which means that it can handle this motor.
