screws. Use the AWK

-3121-M12-RTG device, with wall

mount plates attached, as a guide to mark the correct
locations of the 4 screws. The heads of the screws sh ould
be less than 6.0 mm in diameter, and the shafts 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 apertur es 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
of the keyhole

-shaped

apertures, and then slide the

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 w ire size.
If the current goes above the maximum ratings, the w iring 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 interfer ence, 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 k ept separat e. The ru le 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 th e
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 amou n t 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 tra nsient 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 insta l led outdoors or in an open-air
setting, proper lightning protect ion is required t o prevent d irect lightning
strikes on the AWK device. In order to prevent coupling currents from
nearby lightning strikes, a lightnin g arrester should be installed as pa rt of
your antenna system. Ground the dev ice, antenna, as well as the arrester
properly to provide maximum outdoor protection for the device.

Arrester Accessories

• SA-NMNF-01: Surge arrester, N-type (male) to N-type (female)

• SA-NFNF-01: Surge arrester, N-type (female) to N-type (female)

Wiring the Redundant Power Inputs

The top two pairs of contacts of the 10-contact terminal block connector
on the AWK-3121-M12-RTG’s top panel are used for the
AWK-3121-M12-RTG’s two DC inputs. The top and front views of the
