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.
NOTE
• Do not use solvent, such as acetone, benzene, toluene and alcohol, as these will cause the inverter surface paint to peel off.
• The display, etc. of the operation panel and parameter unit are vulnerable to detergent and alcohol. Therefore, avoid using
them for cleaning.

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.

Inverter parts life display
The inverter diagnoses the control circuit capacitor and the cooling fan by itself, and estimates their lives.
The self-diagnostic warning is output when the life span of each part is near its end. It gives an indication of replacement time.
The life warning output can be used as a guideline for life judgment.
