from damaging the inverter. The motor must be disconnected from the
inverter during the insulation test. A 500 V mega-ohm meter is
recommended, and the tested insulation resistance must not be less
than 5 MΩ.
3. Perform periodic inspection on the terminals to check that the
screws and wiring terminals are not loose. If they are loose, do the
maintenance.
