Cause : Abnormal internal temperature (IP55 compatible models only) comes when the inverter trips when the inverter internal temperature reaches the specified value or higher.
- Check for too high surrounding air temperature.
- Check if the internal air circulation fan or the cooling fan stops due to a fault.
- Install an inverter suitable for the installation environment.
- Replace the internal air circulation fan or the cooling fan.
