(without corrosive gas, flammable gas, oil mist, dust and dirt etc)
CAUTION
For parts replacement, consult the nearest Mitsubishi FA Center.
(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.
