2. Tighten the wire-clamp screws for preventing the wires from loosening.
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 12-56V DC.
Note
PWR1 and PWR2 must provide exactly the same DC voltage
for power load balance while operating with dual power input.
Caution
3.4 Wiring the Alarm Contact
The alarm contacts are in the middle of the terminal block connector as the picture shows
below. Inserting the wires, the Industrial Ethernet Extender 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.
