3.3.7 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 and/or failure of the inverter. For preventive maintenance, the parts must be changed periodically.

Part Name

Standard Replacement

Interval

Description

Cooling fan	2 to 3 years	Change (as required)
Smoothing capacitor in main circuit	5 years	Change (as required)
Smoothing capacitor on control board	5 years	Change the board (as required).
Relays	———	Change as required

CAUTION

For parts replacement, consult the nearest Mitsubishi FA Center.

(1) Cooling fan

The cooling fan used to cool heat-generating parts such as the main circuit semiconductors has a bearing whose life is said to be 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.
