Overview
The AWK-3131A 3-in-1 industrial wireless access point 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-3131A combines two adjacent 20 MHz channels into a
single 40 MHz channel to deliver a potent combination of greater
reliability and more bandwidth. The two redundant DC power inputs
increase the reliability of the power supply, and the AWK-3131A can be
powered via PoE to make deployment easier. The AWK-3131A can
operate on either the 2.4 or the 5 GHz band and is backwards-compatible
with existing 802.11a/b/g deployments.

Wiring Requirements
WARNING
Safety First!
Be sure to disconnect the power cord before installing and/or
wiring your AWK
-3131A.
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.
Read and Follow These Guidelines:
•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 crossing 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.
•For future reference, you should label the wiring used for all of your
devices.
ATTENTION
This product is
intended to be supplied by a Listed Power Unit
marked “Class 2” or “LPS” and rated O/P: 7.2 W

- 8 -
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.
ATTENTION
DO NOT
use a
PoE Injector. Instead, use an IEEE 802.3af or IEEE
802.3at compliant PSE (Power Sourcing Equipment) for PoE
(Power over Ethernet) devices.
Grounding the AWK-3131A
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.
The
potential difference
between any two

must be zero. If the potential
difference is NOT zero, the product could be permanently
damaged.
Installations with Cable Extended Antennas for Outdoor
Applications
If an AWK device or its antenna is installed in an outdoor location, proper
lightning protection is required to prevent direct lightning strikes to the
AWK device. In order to prevent the effects of 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.
