PROTECTION AND LOCATION OF YOUR SET

15.1. If an outside antenna is connected to the television set, be sure the antenna system is grounded so as to provide some

protection against voltage surges and built up static charges, Section 810 of the National Electrical Code, NFPA No.

70-1975, provides 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 electrode, and requirements for the grounding electrode.

15.2. Note to CATV system installer : (Only for the television set with CATV reception)

This reminder is provided to call the CATV system attention to Article 820-40 of the NEC that provides

guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected to the grounding

system of the building, as close to the point of cable entry as practical.

16. An outside antenna system should not be located in the vicinity of overhead power lines or other electric lights or 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.

17. For added protection for this television set during a lightning storm, or when it is left unattended and unused for long

periods of time, unplug it from the wall outlet and disconnect the antenna. This will prevent damage due to lightning

and power-line surges.
