Wall Mounting (optional)
For transportation applications that require an EN 50155 certification
report, we strongly recommend the purchase of the optional
AWK-3131A-M12-RCC wall-mounting kit, which has passed EN 50155
testing. This wall-mounting kit is also convenient for other applications
that require mounting the AWK-3131A-M12-RCC to a wall.
STEP 1:
Remove the aluminum
DIN
-rail attachment plate
from the
AWK
-3131A-M12-RCC, and
then attach the wall mount
plates with M3 screws, as
shown in the adjacent
diagrams.
STEP 2:
Mounting the
AWK-3131A-M12-
RCC to a wall requires
4
screws. Use the AWK-3131A-M12-
RCC 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
-3131A-M12-RCC
downwards, as indicated to the

Wiring Requirements
WARNING
Safety First!
Be sure to disconnect the power cord before installing and/or
wiring your Moxa AWK-3131A-M12-RCC.
WARNING
Safety First!
Calculate the maximum possible current in each power wire and
common wire. Observe all electrical cod
es dictating 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 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.
