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. In order 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.
Arrester Accessories
