The following table lists the subject of the check.
Ambient temperature shall be lower than 40°C. Humidity shall
meet the requirement of 20~90%.
No dust accumulation, no traces of water leakage and no
condensate.
Check the inverter to ensure it has no abnormal heat,
abnormal vibration
Ensure the fan operation is normal, no debris stuck, etc.
