Installation Guide

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.
• 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
The product is intended to be supplied by a UL Listed Power
Unit marked "L.P.S." (or "Limited Power Source") and is rated
9
-30 VDC, 1.57-0.47 A min, Tma min. 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 (includes power cords
and plug assemblies) provided with the unit is certified and
suitable for use in your country or region.
Grounding the AWK-1151C
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 b
e 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.
