You should also pay attention to the following points:
Use separate paths to route wiring for power and devices. If power wiring
and device wiring paths must cross, make sure the wires are perpendicular
at the intersection point.
NOTE: Do not run signal or communications wiring and power wiring in
the same wire conduit. To avoid interference, wires with different signal
characteristics should be routed separately.
You can use the type of signal transmitted through a wire to determine
which wires should be kept separate. The rule of thumb is that wiring that
shares similar electrical characteristics can be bundled together.
Keep input wiring and output wiring separated.
It is strongly advised that you label wiring to all devices in the system when
necessary.
Grounding Moxa Industrial Media
Converter
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.
ATTENTION
This product is intended to be mounted to a well-grounded
mounting surface such as a metal panel.
Wiring the Alarm Contact
The Alarm Contact is made up of the two middle contacts of the terminal block
on IMC’s top panel. 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 an open
circuit when:
1. IMC 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.
If neither of these two conditions occurs, the Fault
circuit will be closed.
