Wiring Requirements

WARNING: Safety First!
Be sure to disconnect the power cord before installing and/or wiring your AWK-4262A.
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.

NOTE If the device is powered by PoE, the PSE equipment and cabling should not be connected to outside facilities.
The product is intended to be supplied by a UL Listed Power Unit marked “L.P.S.” (or “Limited Power Source”) and is rated 1) 12-48 VDC, 2 – 0.5 A min. (supplied by power adapter) or 48 VDC, 0.5 A min. (supplied by PoE), Tma = 75°C. If you need further assistance with purchasing the power source, please contact Moxa for further information.

NOTE If using a Class I adapter, the power cord must be connected to a socket-outlet with an earthing connection.

ATTENTION
Make sure the external power adapter (including power cords and plug assemblies) provided with the unit is certified and suitable for use in your country or region.

ATTENTION
Make sure the PSE (power sourcing equipment) or PoE injector used to power the AWK device complies with IEEE 802.3af or IEEE 802.3at.

Grounding the AWK-4262A
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.

Power Input Pin Assignment
The AWK-4262A can be connected to an IEEE 802.3at compliant Power over Ethernet (PoE) power source. When powered via DC power, the AWK-4262A comes with a M12 A-coded 5-pin power input connector located on the bottom panel of the device. The power input connector contains dual power inputs and a ground pin. Refer to the following figure and table for the detailed pin assignment.

ATTENTION
If the AWK-4262A is connected to a motor or other similar type of equipment, be sure to use power isolation protection. Before connecting the AWK-4262A to the DC power inputs, make sure the DC power source voltage is stable.

Wiring the Digital Inputs and Relay Contact (Digital Output)

The AWK-4262A has two sets of digital input—DI1 and DI2. Each DI comprises two contacts of the 8-pin M12 connector on the AWK-4262A’s bottom panel. These two digital inputs can be connected to digital-output-enabled sensors for on-site status monitoring.
The AWK-4262A also has one relay output, which consists of the two contacts. These relay contacts are used to detect user-configured events. The two wires attached to the Relay contacts form an open circuit when a user-configured event is triggered. If a user-configured event does not occur, the Relay circuit will be closed.
A field-installable plug, M12A-8PMM-IP68, is recommended for connecting the AWK-4262A’s DIs and relay.

Communication Connections
10/100/1000BaseT(X) and 10/100/1000/2500BaseT(X) Ethernet Port Connections
The AWK-4262A has two Ethernet ports (LAN1 and LAN2) with shielded M12 8-pin female X-coded connectors located on the front panel. LAN1 is a 10/100/1000/2500BaseT(X) Ethernet port with PoE functionality, LAN2 is a 10/100/1000BaseT(X) Ethernet port. These two ports are used to connect to Ethernet-enabled devices. Most users configure this port for Auto MDI/MDI-X mode, in which case the port’s pinouts are adjusted automatically depending on the type of Ethernet cable used (straight-through or cross-over), and the type of device (NIC-type or HUB/Switch-type) connected to the port.

RS-232 Connection
The AWK-4262A has one RS-232 5-pin female M12 B-coded console port located on the front panel. Use a 5-pin female M12 B-coded-to-DB9 or RJ45-to-DB25 cable to connect the AWK-4262A’s console port to your
PC’s COM port. You can then use a console terminal program to access the AWK-4262A for console configuration.
