Wiring the Alarm Contact

The Alarm Contact terminal block connector is similar to the power terminal block

connector discussed in the next section. You may refer to the next section for detailed

instructions on how to connect the wires to the terminal block connector, and how to attach

the terminal block connector to the terminal block receptor.

In this section, we explain the meaning of the two contacts used to connect the Alarm

Contact.

FAULT: The two right-most contacts of the 3-terminal terminal block

connector form a closed circuit when MOXA EtherDevice Server is

receiving power from both DC power inputs. The circuit opens if power

to one of the power inputs is cut off, or the MOXA EtherDevice Server

self-test fails.
