2-8 Cooling fan working code:
Cooling fan of inverter is through detecting output power and over temperature
situation to work.
When start to turn on the inverter and output power is under 300W, the cooling fan
does not start running. It complies with saving energy sources requirement. Until,
output power is up to 300W, the cooling fan will start to work in order to drop the
inner temperature.
If the ventilation opening is obstructed, the inverter will enter over temperature
protection mode (OTP). The cooling fan will continue working to drop the inner
temperature. When the temperature comes down to normal situation, the inverter
will turn on automatically.
