Issue Description
Rectifier Protect alarm generate, what should be done?
Solution
Possible Causes:
1) The rectifier input voltage is too high.
2) The rectifier input voltage is too low.
3) The ambient temperature is too high.
4) The rectifier is abnormal.

Measures:

1) Check whether the AC input voltage exceeds the upper threshold of the rectifier working voltage. If yes, rectify the power supply fault and then resume the power supply.

2) Check whether the AC input voltage is below the lower threshold of the rectifier working voltage. If yes, rectify the power supply fault and then resume the power supply.

3) Check whether the ambient temperature is higher than the normal operating temperature of the rectifier. If yes, check and rectify the temperature unit fault.

4) Remove the rectifier that generates the alarm and reinstall it after the indicator turns off. If the alarm still exists, replace the rectifier.
