mount plates attached, as a guide to mark the correct
locations of the 4 screws. The heads of the screws should
be less than 6.0 mm in diameter, and the
s
hafts should
be less than 3.5 mm in diameter, as shown in the figure
at the right.
Do not drive the screws in all the way into the wall—leave a space of about
2 mm to allow room for sliding the wall-mount panel between the wall and
the screws.
NOTE
Test the screw head and shank size by inserting the screws into
one of the keyhole shaped apertures of the
wall-mounting p
lates
before attaching the plates to the wall.
STEP 3:
Once the screws are fixed into
the wall, insert the four screw
heads through the
large opening

Wiring Requirements
WARNING
Safety First!
Be sure to disconnect the power cord before installing and/or
wiring your Moxa AWK-3121-M12-RTG.
WARNING
Safety First!
Calculate the maximum possible current in each power wire and
common wire. Observe all electrical
codes dictating the
maximum current allowed for each wire size.
If the current goes above the maximum ratings, the wiring could
overheat, causing serious damage to your equipment.
You should also pay attention to the following items:
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 with similar electrical characteristics can be bundled
together.
•Keep input wiring and output wiring separate.
•It is strongly advised that you label wiring to all devices in the system
when necessary.

Grounding the Moxa AWK-3121-M12-RTG
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.
Installations with Unstable Power Inputs
There are cases where the device has to be wired to the same power
source as other equipment. In such cases if equipment such as motors
that are connected in the circuit draw a large amount of current during
operation, the transient voltage drop could potentially cause the AWK to
become unstable. Installing a DC/DC power isolator in between the two
equipment is recommended to isolate the transient effect and to ensure a
stable power input for the AWK.

- 9 -
Installations with Cable Extended Antennas for Outdoor
Applications
If the antenna or the AWK device is installed outdoors or in an open-air
setting, proper lightning protection is required to prevent direct lightning
strikes on the AWK device. In order to prevent coupling currents from
nearby lightning strikes, a lightning arrester should be installed as part of
your antenna system. Ground the device, antenna, as well as the arrester
properly to provide maximum outdoor protection for the device.
Arrester Accessories

Communication Connections
10/100BaseT(X) Ethernet Port Connection
All AWK-3121-M12-RTGs have a 10/100BaseT(X) Ethernet port (4-pin
shielded M12 connector with D coding). The 10/100TX port located on the
AWK-3121-M12-RTG front panel is used to connect to Ethernet-enabled
devices. Most users configure this port for Auto MDI/MDI-X mode, in
which case the port’s pinouts are adjusted automatically depending on
the type of Ethernet cable used (straight-through or cross-over), and the
type of device (NIC-type or HUB/Switch-type) connected to the port.
Pinouts for the 10/100BaseT(X) Port
