ATTENTION
Do not locate the antenna near overhead
power lines or other
electric light or power circuits, or where it can come into contact
with such circuits. When installing the antenna, take extreme
care not to come into contact with such circuits, because they
may cause serious injury or death. For pro
per installation and
grounding of the antenna, refer to national and local co
des (for
example, U.S.: NFPA 70;
National Electrical Code (NEC) Article
810; Canada: Canadian Electrical Code, Section 54).
NOTE
For installation flexibility, either the A ante
nna (on the front
panel) or the
B antenna (on the top panel) may be selected for
use. Make sure the antenna connection matches the antenna
s
configured in the AWK
-3131A web interface.
To protect the connectors and RF module, all radio ports should
be termin
ated by either an antenna or a terminator.
We strongly
recommend using resistive terminators for terminating the
unused antenna ports.

-1 and used within its rated electrical and environmental
ratings.
When the AWK
-
3131A is installed in an enclosure, the antennas
must remain internal to the enclosure and not external. External
antenna deployment is allowed only if the antennas are certified
by C1D2, ATEX
Zone 2 or IECEx.
The AWK
