Mounting Dimensions
DIN-Rail Mounting
The aluminum DIN-rail attachment plate comes attached to the back
panel of the AWK-1137C when you take it out of the box. If you need
to reattach the DIN-rail attachment plate to the AWK-1137C, 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.
Unit = mm (inch)
STEP 2:
Gently push the device towards the DIN
rail until the DIN-rail attachment unit
snaps into place as shown below:
To remove the AWK-1137C from the DIN rail, reverse steps 1 and 2.
Wall Mounting (Optional)
For some applications, it may be more convenient to mount the
AWK-1137C to a wall, as illustrated below:
- 6 -
Page 7
STEP 1:
Remove the aluminum
DIN-rail attachment
plate from the
AWK-1137C, and then
attach the
wall-mounting plates
with M3 screws, as
shown in the adjacent
diagrams.
STEP 2:
Mounting the AWK-1137C to a wall requires 2 screws.
Use the AWK-1137C device, with wall-mounting
plates attached, as a guide to mark the correct
locations of the 2 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 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 i nserting the screws into
one of the keyhole shaped apertures of the wall-mounting
plates before they are fixed to the wall.
STEP 3a:
Once the screws are fixed into the
wall, insert the two screw heads
through the large opening of the
keyhole-shaped apertures, and then
slide the AWK-1137C downwards, as
indicated to the right. Tighten the
two screws for added stability.
STEP 3b:
Alternatively, insert four screws
directly through the AWK-1137C
into the wall.

WARNING
Safety First!
Be sure to disconnect the power cord before installing
and/or wiring your Moxa AWK-1137C.
Calculate the maximum possibl e 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.
You should also pay attention to the following items:
• Use s eparate 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.
