Overview The AWK-4252A Series is an industrial-grade AP/bridge/client with IEEE 802.11ac Wave 2 technology. This Series features concurrent dual-band Wi-Fi data transmissions up to 400 Mbps (2.4 GHz mode) and 867 Mbps (5 GHz mode) simultaneously, meeting the speed and flexibility requirements for industrial applications. In addition, the built-in dual band pass filter and the wide-temperature design ensure the reliability and continuous operation in harsh environments.

Mounting Dimensions Wall Mounting For some applications, it may be more convenient to mount the AWK4252A to a wall, as illustrated below. STEP 1: Align the wall-mounting plates to the wall-mounting screw holes on the rear panel, then attach the wallmounting plates with the M5 screws, as shown in the adjacent diagrams. STEP 2: Mounting the AWK-4252A to a wall requires 4 screws.
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.
To remove the AWK-4252A 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-4252A forward and lift it up to remove it from the mounting rail. 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.
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.
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.
NOTE Before connecting the AWK-4252A DC power inputs, make sure the DC power source voltage is stable. • • • • The wiring for the input terminal block shall be installed by a skilled person. Wire type: Cu Only use 16-28 AWG wire size. Use only one conductor in a clamping point between the DC power source and the power input. ATTENTION If the AWK-4252A is connected to a motor or other similar type of equipment, be sure to use power isolation protection.
Communication Connections 10/100/1000BaseT(X) Ethernet Port Connection The 10/100/1000BaseT(X) ports located on the AWK-4252A’s front panel are used to connect to Ethernet-enabled devices.

Installation STEP 1: Attach the gasket ① to the housing ③ STEP 2: Insert the cable (e.g., CAT5e) through the clamp ring ④, screw nut ②, seal ⑤ and housing ③, as follows: STEP 3: Crimp the modular RJ plug to the cable. Note that the use of a snagless cover shield or a strain-relief boot is not recommended here.
LED Indicators The front panel of the AWK-4252A contains several LED indicators. The function of each LED is described in the table below: LED PWR1 Color State Description Front Panel LED Indicators (System) Green On Off On Green Blinking Amber Off On Blinking Off On Green Blinking LAN1 LAN2 Amber Off On Blinking Off On Green Blinking 2.4G On Amber Blinking On Green Blinking 5G On Amber Blinking Red SYS On Blinking On Green Blinking Power is being supplied from power input 1, 2, or PoE.
Specifications Input Current 12-48 VDC, 2.2-0.5 A Input Voltage 12 to 48 VDC, redundant dual power inputs, 48 VDC Power over Ethernet 28 W (max.) Power Consumption Operating Temperature Storage Temperature Wide Temp. Models: -40 to 75°C (-40 to 167°F) -40 to 85°C (-40 to 185°F) NOTE To meet the standard for IP68 protection, all unused ports should be covered with the protective caps. ATTENTION The AWK-4252A is NOT a portable mobile device and should be located at least 20 cm away from the human body.
NOTE For installation flexibility, you can use either antenna 1 or antenna 2. Make sure the antenna connection matches the antennas configured in the AWK-4252A 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. Software Setup This section covers the software setup for the AWK-4252A.
