CONDUCTION INTERFERENCE PREVENTION METHOD.
to suppress the conduction interference from the output side' it is applicable to let all the input cables go through a grounded metal tube.
THE WIRING DISTANCE BETWEEN INVERTER AND MOTOR.
the longer the wiring distance between the inverterand motor is' the higher there carrier frequency is and the gigger the upper harmonics current in the cable is . the current leakage will implement bad effect on the embient equipment . in this case it is necessary to minimize the current leakage. please find below table for the relation between the wiring distance (between the inverter and motor ) and carrier frequency .
