Note
1. The wire gauge for the terminal block should be in the range
between 12 and 24 AWG.
2. The DC power input range is
12-54V DC
.
PWR1 and PWR2 must provide exactly the same DC voltage for
power load balance while operating with dual power input.
2.5 Wiring the Fault Alarm Contact
The fault alarm contacts are in the middle of the terminal block connector as
the picture shows below. When inserting the wires, the Industrial Ethernet
Extender 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.
