4.5 Wiring the Fault Alarm Contact
The fault alarm contacts are in the middle of the terminal block
connector as the picture shows below. After inserting the wires,
the IPOE-171 series will detect the fault status of the power failure
and then form an open circuit. The following illustration shows an
application example for wiring the fault alarm contacts.
1. The wire gauge for the terminal block should be in the
range between 12 ~ 24 AWG.
2. Alarm relay circuit accepts up to 24V, max. 1A
