2.10 Wiring the Fault Alarm Contact
The relay contact of the 2-pin terminal block connector as the picture shows below in
Figure 2.12
is used to
detect user-configured events. The two wires attached to the fault contacts form an open circuit when a
user-configured event is triggered (managed industrial switch only). If a user-configured event does not
occur, the fault circuit remains closed

Wiring the Fault Alarm Contact
Note
● The wire gauge for the terminal block should range between 12 ~ 24 AWG
Note
•
Only use copper conductors, 100
°
C, tighten to 5 lbs.
•
The wire gauge for the terminal block should range between 18~20 AWG
•
To eliminate power fault alarm, jumper Pin 1 to Pin 5 and Pin 2 to Pin 6 when using
only one power supply
2.9 Grounding Note
Grounding and wire routing help limit the effects of noise due to Electromagnetic Interference (EMI).
Run the ground connection from the ground screw to the grounding surface prior to connecting
devices. The grounding screw symbol is shown blow in Figure 2.11.
