FLUXMASTER 50 INSTRUCTION MANUAL
Frequent examination and maintenance is not required for the FM50.To maintain appropriate reliability, please proceed with
the following periodical examination.Remember to turn off the power supply and wait until the Power LED goes off before
proceeding. (Due to the large amount of residual charge in the internal capacitors.)
(1) Clean out internal dust and dirt.
(2) Check mounting screws on every terminal and part.Tighten loose screws.
(3) Dielectric strength test
(a) Remove all conducting wires between the Drive and the outside world.Power must be turned OFF.
(b) The dielectric strength test inside the Drive should be carried out only for FM50 major circuitry. Use a DC 500V: high
resistance meter. Measured resistance should be higher than 100M ohm.
CAUTION
Do not perform dielectric strength test to the control circuit.
