AWK-1137C to a wall requires two
screws. Use
the AWK-1137C device, with
wall
-mounting
plates attached, as a guide to mark the
correct locations of the
two 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 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 M
oxa AWK-1137C.
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.
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 UL
-listed power
adapter suitable for use at
a Thermom
echanical Analysis (TMA) of
7
5 degree Celsius, which output meets SELV circuit and LPS

Grounding the Moxa AWK-1137C
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.
There must be no
electrical potential difference betwee
n any two grounding points
;
otherwise, there is a risk that the device could be destroyed.
Installing Cable Extended Antennas for Outdoor Applications
If the antenna or the AWK device is installed outdoors or in an open-air
setting, proper lightning protection is required to prevent direct lightning
strikes on the AWK device. In order to prevent 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.
