About the built-in cooling fan
The inverter has a built-in cooling fan. The cooling fan has a useful life of approximately 30,000 hours (2 to
3 years when operated continuously), so it needs to be replaced periodically.
If the cooling fan does not operate normally, the temperatures of the internal electrical components will rise
high, and as a result their lives will be shortened. So inspect it periodically.
