Insulation Inspection

Inspection

When the motor is used for the first time, or when the motor is reused after being kept, or when

periodical inspection is performed, it shall conduct motor insulation inspection so as to avoid damaging

the inverter because of the insulation failure of the motor windings. The motor wires must be

disconnected from the inverter during the insulation inspection. It is recommended to use the 500V

megameter, and the insulating resistance measured shall be at least 5M Ω 。

This inverter can provide output frequency of 0Hz to 4 00Hz. If the user needs to run the inverter with

frequency of more than 50Hz, please take the resistant pressure of the mechanical devices .

The inverter may encounter the mechanical resonance point at certain output frequencies, which

can be avoided by setting the skip frequency parameters in the inverter.

Since the output voltage of inverter is PWM wave and contains certain harmonics, the temperature

Since the inverter output is PWM wave, if the capacitor for improving the power factor or

voltage-sensitive resistor for lightning protection is mounted at the output side, it is easy

to cause instantaneous over current in the inverter, which may damage the inverter. It is

recommended that such devices not be used .

If a contactor is installed between the power supply and the input terminal of the inverter, it is not

allowed to use the contactor to control the startup/stop of the inverter. If use of such contactor is

unavoidable, it shall be used with interval of at least one hour. Frequent charge and discharge will

reduce the service life of the capacitor inside the inverter. If switching devices like contactor are installed

between the output end of the inverter and the motor, it shall ensure that the on/off operation is conducted
