Excessive ambient temperature will shorten the service life of the frequency converter. It is recommended to lower the ambient temperature to extend the service life. Blockage of the air duct will affect heat dissipation. Ensure that the air duct is unobstructed to prevent overheating of the frequency converter.
The ambient temperature is too high.
Excessive ambient temperature will shorten the service life of the frequency converter. It is recommended to lower the ambient temperature to extend the service life.
Poor ventilation
Blockage of the air duct will affect heat dissipation. Ensure that the air duct is unobstructed to prevent the inverter from overheating.
Fan card blockage or damage
Fan damage can lead to heat accumulation, so it is recommended to replace the fan to improve heat dissipation.
