  • Page 9: Precautions For Use

    VFD motor. 1.2.2 Confirmation of motor insulation When applying the GK3000 series VFD, please confirm the insulation of the motor before using the motor to prevent damage to the equipment. In addition, please check the insulation of the motor regularly when the environment of the motor is bad, to ensure the safe operation of the system.
  • Page 10 1.2.4 Mechanical resonance point of the load device The VFD may encounter the mechanical resonance point of the load device within a certain range of output frequency, and must be avoided by setting the jump frequency. 1.2.5 Capacitance or varistor for improving power factor Since the output voltage of the VFD is pulse wave type, if the output side is equipped with a capacitor with improved power factor or a varistor for lightning protection, it will cause the VFD to trip or damage the device.

  • Page 11: Disposal Considerations

    In areas where the altitude is more than 1000 meters, the heat dissipation effect of the VFD is deteriorated due to the thin air, and it is necessary to derate the use. Figure 1-2 shows the relationship between the rated current of the VFD and the altitude. Figure 1-2 VFD rated output current and altitude derating diagram 1.2.10 About the degree of protection The protection level IP20 of the GK3000 VFD refers to the degree of protection achieved...
