Installation Precautions
The following general safety precautions must be observed during operation and service of the product. Failure
to comply with these precautions or with specific warnings willfully violates standards of design, manufacture
and intended use of the product.
■ To avoid danger to local personnel in lightning-prone geographic areas, ensure proper techniques are
followed.
■ To protect against voltage surges and built-up static charges, ensure that outdoor equipment is properly
grounded according to local building and electrical code regulations. In the event of a short circuit, grounding
reduces the risk of electrical shock. Refer to Articles 810830 of the National Electrical Code, ANSI/ NFPA No.
70, for information on proper grounding and applicable lightning protection for DC cables.
■ Determine the source and connection points for building-to-earth ground near the antenna location. Proper
grounding of the outdoor equipment reduces electromagnetic interference, provides lightning protection
and protects against electrical discharge.
■ Do not install or operate this equipment in the presence of flammable gases or flumes. Operation of any
electrical instrument in such an environment constitutes a definite safety hazard.
■ Do not install substitute parts or perform any unauthorized modification to the equipment. Changes or
modifications not expressly approved by the vendor may void authority to operate the equipment.
■ Follow local guidelines when attaching an identification tags, for example, to cables, cable ties, and
nameplates.
