Note
The wire gauge for the terminal block should be in the
range between 12 ~ 24 AWG.
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 (available for managed model) 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 ~ 24 AWG.
2. Alarm relay circuit accepts up to 30V, max. 3A
currents.
