Inspection item6.1.6 CleaningAlways run the inverter in a clean status.When cleaning the inverter, gently wipe dirty areas with a soft cloth immersed in neutral detergent or ethanol.CAUTIONDo not use solvent, such as acetone, benzene, toluene and alcohol, as they will cause the inverter surface paint to peel off.The display, etc. of the operation panel (FR-DU07) and parameter unit (FR-PU04/FR-PU07) are vulnerable to detergent andalcohol. Therefore, avoid using them for cleaning.6.1.7 Replacement of partsThe inverter consists of many electronic parts such as semiconductor devices.The following parts may deteriorate with age because of their structures or physical characteristics, leading to reducedperformance or fault of the inverter. For preventive maintenance, the parts must be replaced periodically.Use the life check function as a guidance of parts replacement.Part Name Standard Replacement Interval *1 DescriptionCooling fan 10 years Replace (as required)Main circuit smoothing capacitor 10 years *2 Replace (as required)On-board smoothing capacitor 10 years Replace the board (as required)Relays − as required*1 Replacement years for when the yearly average surrounding air temperature is 40°C(without corrosive gas, flammable gas, oil mist, dust and dirt etc)*2 Output current : 80% of the inverter rated currentCAUTIONFor parts replacement, consult the nearest Mitsubishi FA Center.PRECAUTIONS FOR MAINTENANCE AND INSPECTION6397
