Wiring Requirements

WARNING

Safety First!

Be sure to disconnect the power cord before installing and/or

wiring your

AWK-4252A.

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.

- 9 -

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.

• 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.

NOTE

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, 2.2-0.55 A min. (supplied by power adapter) or

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

DO NOT

use a PoE Injector. Instead, use an IEEE 802.3at

compliant PSE (Power Sourcing Equipment) for PoE (Power over

Ethernet) devices.

Grounding the AWK-4252A

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.

- 10 -

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.

Arrester Accessories

is connected to a motor or other similar type

of equipment, be sure to use power isolation protection. Before

connecting the

AWK-4252A 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-4252A has two sets of digital input—DI1 and DI2. Each DI

comprises of two contacts of the 8-pin M12 connector on the AWK-

4252A’s bottom panel. These two digital inputs can be connected to

digital-output-enabled sensors for on-site status monitoring.

The AWK-4252A 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-4252A’s DIs and relay.
