Antenna grounding

Important Safety Information

English

equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communi- cations. However, this is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, you are encouraged to try to correct the interference by one or more of the following measures:

•Reorient or relocate the receiving antenna.

•Increase the separation between the equipment and receiver.

•Connect the equipment to an outlet on a different circuit than the one to which the receiver is connected.

•Consult the dealer or an experienced radio/ TV technician for help.

Note: Unauthorized modification of the receiver or radio remote control could void the user’s authority to operate this equipment. This product complies with the Canadian ICES-003 Class B specifications.

16.Do not let objects or liquids enter the product – as they may touch dangerous voltage points or short-out parts that could result in a fire or electric shock.

17.See product enclosure for safety related markings.

18.Use proper power sources – Plug the product into a proper power source, as described in the operating instructions or as marked on the product.

19.Avoid power lines – Use extreme care when installing an outside antenna system to keep from touching power lines or circuits, as contact with them may be fatal. Do not install external antennas near overhead power lines or other electric light or power circuits, or where an antenna can fall into such circuits or power lines.

20.Ground all outdoor antennas – If an external antenna or cable system is con- nected to this product, be sure the antenna or cable system is grounded. This will pro- vide some protection against voltage surges and built-up static charges. Section 810 of the National Electrical Code ANSI/ NFPA No.

70provides information with respect to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna-discharge unit, connection to grounding electrodes, and requirements for the ground electrode. Refer to the antenna grounding illustration on this page.

Note to CATV system installer

This reminder is provided to call the CATV sys- tem installer’s attention to Article 820-40 of the NEC (of USA) that provides guidelines for proper grounding. In particular, it specifies that the cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as is practical.
