NOTE
Do not run signal or communications wiring and power wiring in
the same wire co
nduit. 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 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, 2.2-0.55 A min. (supplied by power adapter) or
48
VDC, 0.5 A min. (supplied by PoE), Tma = 75°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 (including 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 802.3at
compliant PSE (Power Sourcing Equipment) for PoE (Power over
Ethernet) devices.
Grounding the AWK-4252A
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.
