Note:
1.
The wire gauge for the terminal block should be in the range of 12 to 24 AWG.
2.
The DC power input range is 48 to 56 VDC
.
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 PoE+ switch detects 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. Wires are inserted into the fault
alarm contacts.
Note:
1. The wire gauge for the terminal block should be in the r
ange of 12 to 24 AWG.
2.
Alarm relay circuits accept uo to 30 V, max. 3 A currents
