5.3.7 Replacement of parts

The inverter consists of many electronic parts such as semiconductor devices.
The following parts may deteriorate with age because of their structural or physical
characteristics, leading to reduced performance or failure of the inverter. For preventive
maintenance, the parts must be changed periodically.

Cooling fan
Smoothing capacitor in main
circuit
Smoothing capacitor on

Note: For part replacement, contact the nearest Mitsubishi FA center.
(1) Cooling fan
The cooling fan cools heat-generating parts such as the main circuit semiconductor
devices. The life of the cooling fan bearing is usually 10,000 to 35,000 hours. Hence,
the cooling fan must be changed every 2 to 3 years if the inverter is run continuously.
When unusual noise and/or vibration is noticed during inspection, the cooling fan must
be changed immediately.
