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 electrica
l 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.
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.
- 8 -
• 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, 2.01-0.5 A min. (supplied by power adapter) or
48
VDC, 0.48 A 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

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. 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.
