Cleaning
Always 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.
6.1.7
Replacement of parts
The inverter consists of many electronic parts such as semiconductor devices.
The following parts may deteriorate with age because of their structures or physical characteristics, leading to reduced
performance 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.
*1 Estimated lifespan 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 current 
CAUTION
Do 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 and
alcohol. Therefore, avoid using them for cleaning.

REMARKS
·
Since repeated inrush currents at power ON will shorten the life of the converter circuit, frequent starts and stops of the
magnetic contactor must be avoided.
CAUTION
For parts replacement, consult the nearest Mitsubishi FA Center.
