Low Ambient Humidity

Low Ambient Humidity

This alarm is generated only for the power system that has a humidity sensor installed.

Possible Causes

  • The low ambient humidity alarm threshold is incorrectly set.
  • The humidity is too low in the cabinet where the humidity sensor is located.
  • The humidity sensor is faulty.


  1. Check whether the low humidity alarm threshold (10% RH by default) is correctly set. If no, adjust it to a proper value.
  2. Check whether the humidity inside the cabinet is too low. If yes, adjust the humidity. The alarm is cleared when the humidity returns to the allowed range.
  3. Check whether the humidity sensor is faulty. If yes, replace the humidity sensor.
