Wall Mounting (Optional)

For some applications, it may be more convenient to mount the AWK-

3251A-M12-RCC to a wall, as illustrated below.

STEP 1:

Remove the aluminum DIN-rail attachment plate from the AWK-3251A-

M12-RCC, and then attach the wall-mounting plates with M3 screws, as

shown in the following diagrams.

STEP 2:

Mounting the

AWK-3251A-M12-RCC to a wall requires 2

screws. Use

the AWK-3251A-M12-RCC device, with

wall

-mounting plates attached, as a guide to mark the

correct locations of the

2 screws on the wall

. The heads

of the screws should be less than 6.0 mm in diameter,

the

shafts should be less than 3.5 mm in diameter,

and

the

screw length should be at least 15 mm, as sho

wn 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.

Wiring Requirements

WARNING

Safety First!

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

wiring your

AWK-3251A-M12-RCC.

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.

- 7 -

NOTE

Do not run signal or communications wiring and power wiring in

the same wire conduit. To avoi

d 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-

0.5A min. (supplied by power adapter) or 48

DC, 0.5A min. (supplied by PoE), Tma = 75 degree 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 (includes 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 802.3af or

IEEE 802.3at

compliant PSE (Power Sourcing Equipment) for

PoE (Power over Ethernet) devices.

ATTENTION

The USB

interface is coded to only support Moxa’s ABC-02

dongle for troubleshooting or debugging purposes.

NOTE

This product can be deployed on vehicles as the control unit’s

wireless interface that collects data from different I/O devices

and transmits the data to vehicle dispatch centers.

Grounding the AWK-3251A-M12-RCC

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.

Arrester Accessories

• SA-NMNF-02: Surge arrester, N-type (male) to N-type (female)

• SA-NFNF-02: Surge arrester, N-type (female) to N-type (female)
