4.3 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 Ethernet 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
