1What the error means
Internal low temperature fault (Inner Under-temperature Fault): the inverter does not start while the ambient temperature is below −25 °C. It recovers on its own once it rises.
2Possible causes
- Ambient temperature below the operating limit
- Faulty temperature sensor
3What to do
- The inverter starts on its own once the temperature rises.
- If it also appears at normal temperature, the sensor needs to be checked.
