Wait until the converter is cooled down. Shutdown temperature see MaxBridgeTemp (4.17). The converter overtemperature alarm will already appear at approximately 5°C below the shutdown temperature.
Check:
- ConvFanAck (10.20)
- FanDly (21.14)
- converter door open
- converter fan supply voltage
- converter fan direction of rotation
- converter fan components
- converter cooling air inlet (e.g. filter)
- converter cooling air outlet
- ambient temperature
- inadmissible load cycle
- connector X12 on SDCS-CON-4
