Mounting Dimensions
Unit = mm (inch)
DIN-Rail Mounting
The aluminum DIN-Rail attachment plate should be fixed to the back
panel of the AWK-3121 when you take it out of the box. If you need to
reattach the DIN-Rail attachment plate to the AWK-3121, make sure the
stiff metal spring is situated towards the top, as shown in the figures
below.
STEP 1:
Insert the top of the DIN
-Rail into
the slot just
below the stiff metal
spring.
STEP 2:
The DIN
-Rail attachment unit will
snap into place as shown below.
To remove the AWK-3121 from the DIN-Rail, simply reverse Steps 1 and
2.

Wall Mounting (optional)
For some applications, it may be more convenient to mount the
AWK-3121 to a wall, as illustrated below.
STEP 1:
Remove the aluminum
DIN
-Rail attachment plate
from the AWK
-3121, and
then attach the wall mount
plates with M3 screws, as
shown in the adjacent
diagrams.
STEP 2:
Mounting the AWK
-3121 to a wall requires 4 screws.
Use the AWK
-3121 device, with wall mount plates
attached, as a guide to mark the correct locations of
the 4 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 at the
right.
Do not screw the screws in all the way—leave a space of about 2 mm to
allow room for sliding the wall mount panel between the wall and the
screws.
NOTE
Test the screw head and shank size by inserting the screw into
one of the keyhole shaped apertures of the Wall Mounting Plates
before it is screwed into 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
-3121 downwards, as
indicated to the right. Tighten the
four screws for added stability.

Wiring Requirements
WARNING
Safety First!
Be sure to disconnect the power cord
before installing and/or
wiring your Moxa AWK-3121.
WARNING
Safety First!
Calculate the maximum possible current in each power wire and
common wire. Observe all electrical codes dictating the
maximum current allowed for e
ach wire size.
If the current goes above the maximum ratings, the wiring could
overheat, causing serious damage to your equipment.
You should also pay attention to the following items:
•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 intersection 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 with similar electrical characteristics can be bundled
together.
•Keep input wiring and output wiring separate.
•It is strongly advised that you label wiring to all devices in the system
when necessary.
ATTENTION
This product is intended to be supplied by a Listed Power Unit
marked
“Class 2” or “LPS” and rated O/P: 12 to 48 VDC
, minimum
6 W (12 V/0.494 A to 48V/0.121 A), 25°C.
ATTENTION
Make sure
the external power adapto
r (includes power cords and
plug assemblies) provided with the unit is certified and suitable
for use in your country.

Grounding the Moxa AWK-3121
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.
Wiring the Redundant Power Inputs
The top two pairs of contacts of the 10-contact terminal block connector
on the AWK-3121’s top panel are used for the AWK-3121’s two DC inputs.
Top and front views of the terminal block connector are shown here.
STEP 1: Insert the negative/positive DC wires
into the
V-/V+ terminals.
STEP 2:
To keep the DC wires from pulling
loose,
use a small flat
-
blade screwdriver to tighten the
wire
-clamp screws on the front of the terminal
block connector.
STEP 3:
Insert the plastic terminal block
connector prongs into the terminal block
receptor, which
is located on the AWK-3121’s t
op
panel.
ATTENTION
Before connecting the
AWK-3121
to the DC power inputs, make
sure the DC power source voltage is stable.
Wiring the Relay Contact
The AWK-3121 has one relay output, which consists of the two contacts of
the terminal block on the AWK-3121’s top panel. Refer to the previous
section for detailed instructions on how to connect the wires to the
terminal block connector, and how to attach the terminal block connector
to the terminal block receptor. These relay contacts are used to indicate
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.

Wiring the Digital Inputs
The AWK-3121 has two sets of digital input—DI1 and DI2. Each DI
comprises two contacts of the 10-pin terminal block connector on the
AWK-3121’s top panel. You can refer to the “Wiring the Redundant Power
Inputs” section for detailed instructions on how to connect the wires to
the terminal block connector, and how to attach the terminal block
connector to the terminal block receptor.
Cable Holder Installation (Optional)
You can attach the cable holder to the bottom of the AWK-3121. This
helps to keep cabling neat and avoid accidents that result from untidy
cables.
STEP 1: Screw the cable holder onto the bottom
of the AWK
-3121.
STEP 2:
After mounting the AWK-3121 and plugging in the LAN cable,
tighten the cable
along the device and wall.
Communication Connections
10/100BaseT(X) Ethernet Port Connection
The 10/100BaseT(X) ports located on the AWK-3121’s front panel are
used to connect to Ethernet-enabled devices.
Below we show pinouts for both MDI (NIC-type) ports and MDI-X
(HUB/Switch-type) ports.

RS-232 Connection
The AWK-3121 has one RS-232 (8-pin RJ45) console port located on the
front panel. Use either an RJ45-to-DB9 or RJ45-to-DB25 cable to connect
the Moxa AWK-3121’s console port to your PC’s COM port. You may then
use a console terminal program to access the AWK-3121 for console
configuration.
