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/1CXT 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.

The wire gauge for the terminal block should be in the

range between 12 ~ 24 AWG.

The alarm relay circuit accepts up to 30V, max. 3A currents.
