Wall Mounting
In most applications, wall mount provides an easier installation. You will
find it quite easy to mount AWK-4131 on the wall, as illustrated below.
STEP 1:
Attach the wall
-mounting kit
with M4 screws, as shown in
the diagram below.
STEP 2:
Mounting the AWK
-4131 on the wall
requires 4 screws. Use the AWK
-4131
device, with wall
-mounting kit
attached, as a guide to mark the correct
locations of the 4 screws. The heads of
the screws are recommended to be
between 5.5mm and 8.5 mm in
diameter, and the shafts should not be
more than 5.0 mm
in diameter, as
shown in the figure.
Do not drive the screws in all the way in to the wall—leave a space of
about 2 mm to allow room for sliding the wall-mounting kit between the
wall and the screws.
ATTENTION
T
est the screw head and shank size by inserting the screws
into
one of the keyhole shaped apertures of the wall
-
mounting plates
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 AWK-4131 downwards, as indicated to the right. Tighten the
four screws for added stability.
ATTENTION
To avoid environmental vibration or shock, you can consider a
robust
installation with four bigger screws, the shafts of which
are
between 7.0 mm and 8.5 mm in diameter, and fix the AWK
-
4131
directly on to the wall.

- 7 -
DIN-Rail Mounting (Optional)
The DK-DC50131 die-cast metal kit, which
can be bought separately,
can enable easy
and robust installation for the AWK
-4131.
A
pair of DK
-DC50131s is needed for DIN-r
ail
mounting.
To install
the DIN-r
ail mounting kits, tightly
attach the two DIN
-r
ail mounting kits on the
rear panel of AWK
-4131
with 12 screws. (6
screws for each kit)
To Install
STEP 1:

on the spring
-loaded
bracket to lock it in
position.
STEP 2:
Insert the top of the DIN
r
ail into the slot just
b
elow the upper hook of the DIN-rail
mounting kit. Push the
AWK-4131 toward
the DIN r
ail until the DIN-rail attachment
bracket snaps into place.
To Release
STEP 1:
Pull out the two spring
-loaded
brackets
from the bottom until
they are fixed in the “release”
position.
STEP 2:
Pull the AWK
-4131
out and upward.

Wiring Requirements
WARNING
Safety First!
Be sure to disconnect the power cord before installing and/or
wiring your Moxa AWK
-4131.
Calculate the maximum possible current in each power wire and
common wire. Observe all
electrical codes dictating the
maximum current allowable 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
for easy identification.
Grounding Moxa AWK-4131
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. There must be no
potential difference between two ground potentials, otherwise
there is a risk that the device could be destroyed.
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
•SA-NMNF-01: Surge arrester, N-type (male) to N-type (female)
•SA-NFNF-01: Surge arrester, N-type (female) to N-type (female)

- 10 -
Wiring the Redundant Power Inputs
The AWK-4131 must be connected to a power-over-Ethernet (PoE) IEEE
802.3af compliant power source or an IEC60950 compliant limited power
source. When AWK-4131 is powered via DC power, the M12 A-coding
connector on the bottom panel is used for the AWK-4131’s two redundant
inputs. The pin assignment is shown below:
Pin

ATTENTION
This product is intended to be supplied by a Listed Power Unit
marked “Class 2” or “LPS” and rated O/P: 12 to 48 VDC, 890mA
(max.), 25°C
.
Make sure external power a
dapter (includes power cords and
plug assemblies) provided with the unit is certified and suitable
for use in your country.
Before connecting the AWK
-
4131 to the DC power inputs, make
sure the DC power source voltage is stable.
ATTENTION
Do not use
the PoE Injector with the PoE (Power-over-
Ethernet)
model
. Instead, use an IEEE802.3af or IEEE802.3at compliant
PSE (Power Sourcing Equipment).
Wiring the Digital Inputs and Relay Contact
(Digital Output)
The AWK-4131 has two sets of digital input—DI1 and DI2. Each DI
comprises two contacts of the 8-pin M12 connector on the AWK-4131’s
bottom panel. These two digital inputs can be connected to
digital-output-enabled sensors for on-site status monitoring.
The AWK-4131 also has one relay output, which consists of the two
contacts. These relay contacts are used to detect user-configured events.
The two wires attached to the Relay contacts form an open circuit when a
user-configured event is triggered. If a user-configured event does not
occur, the Relay circuit will be closed.

- 11 -
A field-installable plug, M12A-8PF-IP67, is recommended for
connecting the AWK-4131’s DIs and relay.
Communication Connections
Connecting the Data Lines
10/100/1000BaseT(X) Ethernet Port Connection
AWK-4131 has 10/100/1000BaseT(X) Ethernet ports (8-pin shielded M12
connector with A coding). The 10/100/1000BaseT(X) ports located on the
AWK-4131’s bottom panel are used to connect to Ethernet-enabled
devices. Below we show pinouts for both MDI (NIC-type) ports and MDI-X

ATTENTION
Do not locate the antenna near overhead power lines or other
electric light or power circuits, or where it can come into contact
with such circuits. When installing the antenna
, take extreme
care not to come into contact with such circuits, because they
may cause serious injury or death
when there is a surge. For
instructions on
proper installation and grounding of the antenna
,
refer to national and local codes (for example, U.S.:
NFPA 70;
Nat
ional Electrical Code, Article 810;
Canada: Canadian Electrical
Code, Section 54).
NOTE
For installation flexibility, either the A antenna or the B antenna
may be selected for use. Make sure the antenna connection
matches the antenna config
ured in the AWK-4131 web
interface.
To protect the connectors and RF module, all radio ports should
be terminated by either an antenna or a terminator. We strongly
recommend
using resistive terminators for terminating the
unused antenna ports.
ATTENTION
An IP68
-rated field installable plug, which is available in the AWK
-
4000 and AWK
-6000 series' accessory pack, may be needed to
ensure IP68 connectivity. For details, refer to the
product
installation guide.
