3.5 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 PoE++ Switch will
detect the fault status of the power failure and then forms an open circuit. The
following illustration shows an application example for wiring the fault alarm
contacts.
