IGBT overheating
IGBT temperature exceeds protection level 1 to15HP: 90 o C 20 to 100HP: 100 o C.
1. Ensure that the ambient temperature falls within the specified temperature range.
2. Make sure that the ventilation holes are not obstructed.
3. Remove any foreign objects from the heatsinks and check for possible dirty heat sink fins.
4. Check the fan and clean it.
5. Provide enough spacing for adequate ventilation.
