Check part Check item
Filtering 1) Check for electrolyte leakage,
capacitor discoloration, cracks and
swelling of the case.
(Note 1)
2) Check if the safety valve does
not protrude excessively
3) Measure the capacitance if
necessary.
Braking 1) Check for odor caused by
resistor overheat and cracked
insulator.
2) Check for broken wire.
Transformer Check for abnormal noise and
and reactor odor.
Magnetic 1) Check for chatters during
contactor operation.
and relay
2) Check for rough contacts.
Printed 1) Check for loose screws and
circuit board connectors.
(Note 1) 2) Check for odor and
discoloration.
3) Check for cracks, breakage,
deformation and excessive
rust.
4) Check the capacitors for
electrolyte leaks and
deformation.
Cooling fan 1) Check for abnormal noise
and excessive vibration.
(Note 1)
2) Check for loose bolts.
3) Check for discoloration
caused by overheat.
Ventilation Check the heat sink, intake and
path exhaust ports for clogging and
foreign matter.
(Note 1) The judgement level of part replacement period with Menu #5 "Maintenance information" should be
used as a guide. Determine the replacement period on the basis of the standard replacement years. (See
Section 7.5 "List of Periodical Replacement Parts.")
If the inverter is stained, wipe it off with a chemically neutral cloth to remove dust, use a vacuum
cleaner.
