shows. By inserting the wires, it will detect the fault status which the power is failure or
port link failure and form a closed circuit. And, application example for the fault alarm
contact as below:
[NOTE]
The wire gauge for the terminal block should be in the 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.
