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 onto 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.

To remove the AWK-3252A from the DIN rail, do the following: STEP 1:
Pull down the latch on the DINrail kit with a screwdriver.
STEP 2 & 3:
Slightly pull the AWK-3252Aforward 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 AWK3252A to a wall, as illustrated below.

STEP 1:
Remove the aluminum DINrail 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 wall-mounting plates before they are fixed 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- 3252A downwards, as
indicated to the right. Tighten the three screws for added stability.

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 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: 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 to 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 arrester properly to provide maximum outdoor protection for the device.
