4.2 Maintenance and Examination
Frequent examination and maintenance is not required for the inverter.
To maintain appropriate reliability, please proceed with the following periodical examina-
tion. Remember to turn off power supply and wait until the Power LED goes off before
proceeding. (Due to the large amount of remaining charge 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 inverter
power circuitry. Use DC500V: high resistance meter. Measured resistance
should be higher than 100M ohm.
(c) Disconnect and remove control PCB prior to dielectric test.
CAUTION! : Do not perform dielectric strength test to the control circuit.
