9. FAQ：

Q1: Why is the three-phase four-wire leakage circuit breaker used in inverter frequently tripping?

A1: In the inverter control system, there are many occasions or extended before installing frequency converter using three phase four wire system leakage circuit breaker, the frequency converter operation, a frequency converter in the case of frequent tripping during normal use.Reason is because of the general inverter runtime contained in the output voltage harmonic component, so that the motor winding and shell, and the wire to the ground between parasitic capacitance, the parasitic capacitance through wires and earth, the earth and chassis, constitute the leakage current, when the leakage current is greater than the current value of residual current circuit breaker, leakage circuit breaker will move in the trip.Therefore, in the control system of using frequency converter, in case the above situation, need to replace the original residual current circuit breaker or setting up the current value of the residual

Q2. Why can't the "land" of the converter connect to the zero line?

A2: TT system (three phase four wire system) of the zero line access circuit, contains more harmonic and various clutter, sometimes there will be a few volts or even hundreds of volts, once the "to" connected to the zero line of frequency converter, could the harmonic and various clutter is introduced into the converter internal interference formation, affect the normal work frequency converter.Therefore, the general frequency converter should be independently grounded.
