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
MC251-4P/1S and the NS2051-4P/1T 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.
