8.1.1 General Installation Warnings
,
ATTENTION
•
Professional Installation is required to ensure conformity
with Federal Communications Commission (FCC) in the
USA and Industry Canada (IC) in Canada.
•
Professional installation is required for the selection
and installation of approved antennas and setup of the
maximum allowable radiated power from the Limitless™
WMPR Series as configured for the particular installation
site.
•
The antenna used for this sensor must be installed to
provide a separation distance of at least 20 cm [7.87 in]
from all persons and must not be co-located or operating
in conjunction with any other antenna or sensor.
•
For remote antenna, see antenna installation require-
ments to satisfy FCC RF exposure requirements.
,
ATTENTION
Federal Communications Commission (FCC):
•
The Limitless™ WMPR Series complies with part 15 of
the FCC rules. Operation is subject to the following two
conditions: (1) this device may not cause harmful inter-
ference, and (2) this device must accept any interference
received, including interference that may cause unde-
sired operation.
Industry Canada (IC):
•
L’installateur de cette radio doit s’assurer que l’antenne
est située ou orientée de manière à ne pas émettre de
radiofréquences excédant les limites permises par Santé
Canada pour la population générale. Veuillez consulter
le Code de sécurité 6 de Santé Canada au www.hc-sc.

8.1.2 Outdoor Installation Warnings
m
WARNING
LIVES MAY BE AT RISK!
Carefully observe these instructions and any special
instructions included with the equipment being installed.
m
WARNING
CONTACTING POWER LINES COULD BE FATAL
Look over the site before beginning any installation and
anticipate possible hazards, especially these:
•
Make sure no power lines are near where possible con-
tact can be made. Antennas, masts, towers, guy wires, or
cables may lean or fall and contact these lines. People
may be injured or killed if they are touching or holding
any part of equipment when it contacts electric lines.
Make sure there is NO possibility that equipment or
personnel can come in contact directly or indirectly with
power lines.
•
Assume all overhead lines are power lines.
•
The horizontal distance from a tower, mast, or antenna to
the nearest power line should be at least twice the total
length of the mast/antenna combination. This will ensure
that the mast will not contact power if it falls during
either installation or later.
m
WARNING
TO AVOID FALLING, USE SAFE PROCEDURES
WHEN WORKING AT HEIGHTS ABOVE GROUND
•
Select equipment locations that will allow safe, simple
equipment installation
•
Don’t work alone. A friend or co-worker can save a life if
an accident happens.
•
Use approved, non-conducting ladders and other safety
equipment. Make sure all equipment is in good repair.
•
If a tower or mast begins falling, don’t attempt to catch it.
Stand back and let it fall.
•
If anything such as a wire or mast does come in contact
with a power line, DON’T TOUCH IT OR ATTEMPT TO
MOVE IT. Instead, save a life by calling the power compa-
ny.
•
Don’t attempt to erect antennas or towers on windy days.
m
WARNING
MAKE SURE ALL TOWERS AND MASTS ARE
SECURELY GROUNDED, AND ELECTRICAL
CABLES CONNECTED TO ANTENNAS HAVE
LIGHTNING ARRESTORS.
This will help prevent fire damage or human injury in
case of lightning, static build up, or short circuit within
equipment connected to antenna.
•
The base of the antenna mast or tower must be connect-
ed directly to the building protective ground or to one-or-
more approved grounding rods, using 1 AWG ground wire
and corrosion-resistant connectors.
•
Refer to the National Electrical Code for grounding de-
tails.
•
Lightning arrestors for antenna feed coaxial cables are
available from electrical supply houses.
