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.

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 between any two grounding 
points
; otherwise, there is a risk that the device could be 
destroyed.
