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
If a person comes in contact with electrical power, and
cannot move
DO NOT TOUCH THAT PERSON OR RISK
ELECTROCUTION.
•
Use a non-conductive dry board, stick, or rope to push,
pull, or drag them so they no longer are in contact with
electrical power.
•
Once they are no longer contacting electrical power,
administer CPR if certified, and make sure emergency
medical aid has been requested.
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 company.
•
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 de-
termined as 'Simple Apparatus' is allowed and approved
for use.
, ATTENTION
When the WBX switch is being installed or operating in a
hazardous environment, the end customer/user should
issue a work permit to a trained professional installer prior
to any work performed on the WBX Series limit switch. This
includes the following actions:
•
Installation and/or operation of the WBX Series limit
switch
•
Installation and/or adjustment of a remote antenna for
the WBX Series limit switch
•
Maintenance on the WBX Series limit switch, including
battery replacement, pairing, purging, etc.
