Hardware Description
2.4 Wiring the Fault Alarm Contact
The fault alarm contacts are in the middle of the terminal block as the picture shows below. Connect the wires to form a
normally close circuit. When fault events including power failure/port link failure occur, the loop will become an open circuit.
Insert the wires into the fault alarm contacts.
Note:
Use Copper Conductors Only, Tighten to 5 lb-in
Note:
The wire gauge for the terminal block should be in the range between 12~ 24 AWG.
