Corrective Actions
1. Check if the input voltage is normal
2. Check for possible sudden load
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.
1. Ensure that the ambient temperature
falls within the specified temperature
range.
2. Make sure heat sink is not obstructed.
Check if the fan is operating
℃
3. Check if there is enough ventilation
clearance for AC motor drive.
