inverter is OFF. Otherwise, the residual charge on the capacitor may cause personal
injury!
3. The inverter shall be repaired and maintained only by the qualified person who
has received professional training. Otherwise, it may cause personal injury or
equipment damage!
1.2 Precautions
1.2.1 Motor Insulation 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 mega
meter, and the insulating resistance measured shall be at least 5MΩ.
1.2.2 Thermal Protection of the Motor
If the ratings of the motor does not match those of the inverter, especially
when the rated power of the inverter is higher than the rated power of the motor, the
relevant motor protection parameters in the in the inverter shall be adjusted, or
thermal relay shall be mounted to protect the motor.
1.2.3 Running with Frequency higher than Standard Frequency
This inverter can provide output frequency of 0Hz to 400Hz. If the user needs
to run the inverter with frequency of more than 50Hz, please take the resistant
pressure of the mechanical devices into consideration.
1.2.4 Vibration of Mechanical Device
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.
