Note Actions taken to ensure proper running
Do not perform any live operation on the VFD, motor, or motor cables.
Only trained and qualified professionals can operate the VFD.
When you need to maintain the VFD, motor, or motor cable, do as follows before the
maintenance: Check the power indicator first, wait for 25 minutes after the power
indicator is turned off, and then confirm that the internal bus capacitance of the VFD
has been discharged. To check whether the discharge is completed, you can use a
multimeter and an attenuation probe to measure whether the voltage between the VFD
bus terminals (+) and (-) is below 36V.
Do not have live contact with the VFD control part or the external circuit connected to
the VFD control part, because the external control circuit may cause dangerous voltage
to be generated inside the VFD even if the VFD is powered off.
Do not perform the insulation withstand voltage test on the VFD as our products has
already been tested for voltage withstand at the factory.
When the motor needs to be re-connected, check whether the motor cable phase
sequence is correct.
