Chapter 2: Installation
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 a 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:
The wire gauge for the terminal block should be in the range between 12 ~ 24
AWG. Alarm relay circuit accepts up to 30V, max. 3A currents.
