Safety Information
Warning When using a DC input voltage source, observe this warning statement:
Connect the unit only to DC power source that complies with the safety extra-low voltage (SELV)
requirements in IEC 60950 based safety standards.
Statement 1033
Warning When installing or replacing the unit, the ground connection must always be made first and
disconnected last.
Statement 1046.
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, because they may cause serious injury or death. For
proper installation and grounding of the antenna, please refer to national and local codes (for
example, U.S.:NFPA 70, National Electrical Code, Article 810, Canada: Canadian Electrical Code,
Section 54).
Statement 1052
Caution
Before connecting or disconnecting a power cord, you must remove power from the power source using
a suitable service disconnect.
For safety and to achieve a good installation, please read and follow these safety precautions:
• Select your installation site with safety, as well as performance in mind. Remember: electric power
lines and phone lines look alike. For safety, assume that any overhead line can kill.
•
Call your electric power company. Tell them your plans, and ask them to come look at your proposed
installation.
•
Plan your installation carefully and completely before you begin. Successful raising of a mast or
tower is largely a matter of coordination. Each person should be assigned to a specific task and
should know what to do and when to do it. One person should be in charge of the operation to issue
instructions and watch for signs of trouble.
•
When installing the access point and antennas, remember:
–
Do not use a metal ladder.
–
Do not work on a wet or windy day.
– Do dress properly—shoes with rubber soles and heels, rubber gloves, long sleeved shirt or
jacket.
•
Use a rope to lift the access point. If the assembly starts to drop, get away from it and let it fall.
•
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. They will remove it safely.
If an accident should occur, call for qualified emergency help immediately.
