Wiring the Fault Alarm Contact
The fault alarm contact is in the middle of the terminal block connector as the picture
shows below. By inserting the wires, it will detect the fault status including power failure
or port link failure (managed industrial switch only) and form a normally open circuit. An
application example for the fault alarm contact is shown as below:
Note
The wire gauge for the terminal block should range between 12 ~ 24
AWG.
If only using one power source, jumper Pin 1 to Pin 5 and Pin 2 to
Pin 6 to eliminate power fault alarm.
