Wiring the Fault Alarm Contact
The fault alarm contact is in the middle of terminal block connector as the picture shows below. When the wires are inserted into ports 3 and 4, they automatically detect the fault status in the event of a power failure by forming an open circuit.
An example for the fault alarm contact is shown as below:
Insert the wires into the fault alarm contact.
The wire gauge for the terminal block should be in the range between 12 ~ 24 AWG.
