Mounting Dimensions
DIN-Rail Mounting
When shipped, the metal DIN-rail mounting kit is fixed to the back
panel of the AWK-3252A. Mount the AWK-3252A on to a 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-3252A towards the
mounting rail until it snaps into
place.

- 5 -
To remove the AWK-3252A 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-3252A
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-
3252A to a wall, as illustrated below.
STEP 1:
Remove the aluminum DIN-
rail attachment plate from
the
AWK-3252A, and then
attach the wall
-mounting
plates with M3 screws, as
shown in the adjacent
diagrams.
STEP 2:
Mounting the
AWK-3252A to a wall requires 3 screws.
Use
the AWK-3252A device, with wall-mounting plates
attached, as a guide to mark the correct locations of
the 3 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 w
all-mounting
plates before they are fixed to the wall.

- 6 -
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-3252A downwards, as
indicated to the ri
ght. Tighten the

Wiring Requirements
WARNING
Safety First!
Be sure to disconnect the power cord before installing and/or
wiring your
AWK-3252A.
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 co
nduit. To avoid interference, wires with
different signal characteristics should be routed separately.

- 7 -
•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: 22 W
ATTENTION
Make sure
the external power adapter (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-3252A
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
grounding points 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.
