Inspection item
(1) Cooling fan
The replacement interval of the cooling fan used for cooling the parts generating heat such as the main circuit
semiconductor is greatly affected by the ambient temperature. When unusual noise and/or vibration is noticed during
inspection, the cooling fan must be replaced immediately.
CAUTION
For parts replacement, consult the nearest Mitsubishi FA Center.
