Cause : Internal overtemperature alarm comes whenhe temperature inside the converter has exceeded the permissible limit value of the alarm threshold.
- insufficient cooling, fan failure.
- overload.
- ambient temperature too high.
- possibly use an additional fan.
- check whether the ambient temperature is in the permissible range.
