2.1.6 Wiring the Fault Alarm Contact

The fault alarm contacts are in the middle of the terminal block

connector as the picture shows below. Inserting the wires, the

Industrial Gigabit Ethernet Switch will detect the fault status of the

power failure, or port link failure and then forms an open circuit. The

following illustration shows an application example for wiring the fault

alarm contacts.

Note

1. The wire gauge for the terminal block should be in

the range between 12 and 24 AWG.
