Safety Precautions
Safety Precautions
Warning
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, as they may cause serious injury or death. For proper
installation and grounding of the antenna, please refer to national and local codes (e.g. U.S.: NFPA 70,
National Electrical Code, Article 810, Canada: Canadian Electrical Code, Section 54).
Statement 280
For your safety, read and follow these safety precautions.
1. Before you install an antenna, contact your Cisco account representative to explain which mounting
method to use for the size and type of antenna that you are about to install.
2. Find someone to help you—installing an antenna is often a two-person job.
3. Select your installation site with safety, as well as performance, in mind. Remember that electric
power lines and phone lines look alike. For your safety, assume that any overhead line can kill you.
4. Contact your electric power company. Tell them your plans and ask them to come look at your
proposed installation.
5. Plan your installation carefully and completely before you begin. Each person involved in an
in stallati o n should be a ssigned t o a specific task, an d should kn ow what t o do and whe n to do it. On e
person should be in charge of the operation to issue instructions and watch for signs of trouble.
6. When installing your antenna, follow these guidelines:
a. Do not use a metal ladder.
b. Do not work on a wet or windy day.
c. Do dress properly—wear shoes with rubber soles and heels, rubber gloves, and a long-sleeved
shirt or jacket.
7. If the assembly starts to drop, move away from it and let it fall. Because the antenna, mast, cable,
and metal guy wires are all excellent conductors of electrical current, even the slightest touch of any
of these parts to a power line completes an electrical path through the antenna and the installer.
8. If any part of the antenna system should come in contact with a power line, do not touch it or try to
remove it yourself. Call your local power company to have it removed safely.
9. If an accident should occur with the power lines, call for qualified emergency help immediately.
