6.8 Maintenance and Examination
Frequent examination and maintenance is not required for the inverter.
To maintain appropriate reliability, please proceed with following periodical examination.
Remember to turn off power supply and wait till the Power LED goes off before proceed. (Due
to the large amount of remaining charges in the internal capacitors.)
(1) Clean out internal dust and dirt.
(2) Check out mounting screws on every terminal and parts. Tighten loose screws.
(3) Dielectric strength test
(a) Remove all conducting wires between Drive and outside world. Power must be
turned OFF.
(b)The dielectric strength test inside Drive should be carried out only for RVDF major
circuitry. Use DC 500V: high resistance meter. Measured resistance should be higher
than 100M ohm.
CAUTION: Do not perform dielectric strength test to the control circuit.
