Overview
The AWK-1137C industrial Wi-Fi client meets the growing need for faster
data transmission speeds and wider coverage by supporting IEEE
802.11n technology with a net data rate of up to 300 Mbps. The
AWK-1137C combines two adjacent 20 MHz channels into a single 40 MHz
channel to deliver a potent combination of greater reliability and more
bandwidth. The AWK-1137C can operate on either the 2.4 GHz or the
5 GHz band and is backward compatible with existing 802.11a/b/g
deployments.
Hardware Setup
This section covers the hardware setup for the AWK-1137C.

Mounting Dimensions
DIN-Rail Mounting
When shipped, the metal DIN-rail mounting kit is fixed to the back panel
of the AWK-1137C. Mount the AWK-1137C on the corrosion-free
mounting rail that adheres to the EN 60715 standard.
STEP 1:
Insert the upper lip of
the
DIN
-rail kit into the mounting
rail.
STEP 2:
Press the AWK
-1137C towards the
mounting rail until it
snaps
into place.
Unit = mm (inch)

- 5 -
To remove the AWK-1137C from the DIN rail, do the following:
STEP 1:
Pull down the latch on the
DIN
-rail kit with a screwdriver.
STEP 2 & 3:
Slightly pull the
AWK
-1137C forward and lift it up
to remove it from the mounting
rail.
Wall Mounting (Optional)
For some applications, it may be more convenient to mount the
AWK-1137C to a wall, as illustrated below:
STEP 1:
Remove the aluminum
DIN
-rail attachment
plate from the
AWK
-1137C, and then
attach the
wall
-mounting plates
with M3 screws,
as
shown in the adjacent
diagrams.
STEP 2:
Mounting the
AWK-1137C to a wall requires two
screws. Use
the AWK-1137C device, with
wall
-mounting
plates attached, as a guide to mark the
correct locations of the
two screws. The heads of the
screws should 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 on the right.
Do not drive the screws in all the way—leave a space of about 2 mm to
allow room for sliding the wall-mounting 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 plates
before they are fixed to the wall.

- 6 -
STEP 3a:
Once the screws are fixed into the wall, insert the two screw heads
through the large opening of the keyhole-shaped apertures, and then
slide the AWK-1137C downwards, as indicated to the right. Tighten the
two screws for added stability.
STEP 3b:
Alternatively, i
nsert four screws directly
through the AWK
-1137C into the wall.
WARNING
•
This equipment is intended to be used in a
Restricted Access
Location, such as a dedicated computer room where only
authorized service personnel or users can gain access.
Such
personnel must be instructed about the fact that the metal
chassis of the equipment is extremely hot and may cause
burns.
•
Service personnel
or users have to pay special attention and
take special precautions before handling this equipment.
•
Only authorized, well-trained professionals s
hould be allowed
to access the Restricted Access Location. Access should be
controlled by the authority responsible for the location with
a
lock and key or a security identity system.
•
External metal parts are hot!! Pay special attention or
use
special protection before handling this equipment.

Wiring Requirements
WARNING
Safety First!
Be sure to disconnect the power cord before installing and/or
wiring your M
oxa AWK-1137C.
Calculate the maximum possible current in each power wire and
common wire. Observe all electrical codes that dictate 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.
ATTENTION
This product is intended to be supplied by a UL
-listed power
adapter suitable for use at
a Thermom
echanical Analysis (TMA) of
7
5 degree Celsius, which output meets SELV circuit and LPS
standards;
output rated 9 to 30 VDC, 1.3A min. or 24 VDC
, 0.49A
min.
ATTENTION
Make sure
the external power adapte
r (includes power cords and
plug assemblies) provided with the unit is certified and suitable
for use in your country.

Grounding the Moxa AWK-1137C
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
electrical potential difference betwee
n any two grounding points
;
otherwise, there is a risk that the device could be destroyed.
Installing 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)

Wiring the Power Input
The 3-contact terminal block connector on the AWK-1137C’s side panel is
used for the AWK-1137C’s DC input. The top and front views of the
terminal block connector are shown below:
STEP 1:
Insert the negative/positive DC wires into the
V-/
V+
terminals.
STEP 2:
To keep the DC wires from pulling
loose, use a small
flat
-blade screwdriver to tighten the wire-clamp
screws on the front of the terminal block c
onnector.
STEP 3:
Insert the plastic terminal block connector prongs
into the terminal block receptor, which is located on
the
AWK-1137C’s side panel.
NOTE
Input Terminal Block (CN1) is suitable for wire size range of
12
-28 AWG (3.31-0.0804 mm²) and a torque value of 4.5 lb-in
(0.51 Nm)
ATTENTION
If the AWK
-
1137C is connected to a motor or other similar type of
equipment, be sure to use power isolation protection. Before
connecting the
AWK-1137C to the DC power inputs, make sure
the DC power source voltage is stable.
Using the Reset Button
The Reset button is used to load the factory default settings. Use a
pointed object to hold the Reset button down for five seconds to load the
factory defaults.
Activating AeroMag Function
Push the Reset Button five times to activate AeroMag. To deactivate it
again, push the Reset Button three times.

Installing the Antenna-Locking Clamp
Use the antenna-locking clamp to secure the antennas to the AWK-1137C
for added stability when you install the device in a high-vibration
environment.
STEP 1:
Slide the
locking clamps through
the
antenna port
s.
STEP 2:
Use s
crews to fix the clamps to the
side
panel of the AWK-1137C as
shown below:
