Grounding Moxa EtherDevice Switch
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.
A 4 mm
2
conductor must be used when a connection to the external
grounding screw is utilized.
product is intended to be mounted to a well-grounded
mounting surface, such as a metal panel.
Wiring the Alarm Contact
The Alarm Contact consists of the two middle contacts of the terminal
block on EDS’s top panel. 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 middle contacts of the 6-
contact
terminal block connector are used to
detect both power faults and port faults. The
two wires attached to the Fault contacts form
a
n open circuit when:
1. The EDS has lost power from one of the
DC power inputs.
OR
2. One of the ports for which the
corresponding PORT ALARM DIP Switch
is set to ON is not properly connected.
neither of these two conditions is satisfied,
the Fault circuit will be closed.
