Safety information

•Follow all warnings and instructions marked on the television.

•If an outside antenna or cable system is connected to the television, be sure the antenna or cable system is grounded so as to provide some protection against voltage surges and built-up static charges. Article 810 of the National Electrical Code, ANSI/ NFPA 70, provides information with regard 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 grounding electrode.

Antenna lead-in wire

 

•Use No. 10 AWG (5.3 mm2) copper, No. 8 AWG (8.4 mm2) aluminum, No. 17 AWG (1.0 mm2) copper-clad steel or bronze wire, or larger, as a ground wire.

•Secure antenna lead-in and ground wires to house with stand-off insulators spaced from 4-6 feet (1.22 -1.83 m) apart.

•Mount antenna discharge unit as close as possible to where lead-in enters house.

•Use jumper wire not smaller than No. 6 AWG (13.3 mm2) copper, or the equivalent, when a separate antenna-grounding electrode is used. See ANSI/NFPA70.

•An outside antenna system should not be located in the vicinity of overhead power circuits, or where it can fall into such power lines or circuits. When installing an outside antenna system, extreme care should be taken to keep from touching such power lines or circuits as contact with them might be fatal.
