Lenoxx Electronics CR-776 Example of Antenna Grounding AS PER National Electrical Code

SAFETY INSTRUCTIONS

11.Power Cord Protection - Power supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenient receptacles, and the point where they exit from the appliance.

12.Cleaning - The appliance should be cleaned only as recommended by the manufacturer.

13.Nonuse periods - The power cord of the appliance should be unplugged from the outlet when left unused for a long period of time.

14.Object and Liquid Entry - Care should be taken so that objects do not fall and liquids are not spilled into the enclosure through openings.

15.Damage Requiring Service - The appliance should be serviced by qualified service personnel when:

A.The power supply cord or the plug has been damaged; or

B.Objects have fallen, or liquid been spilled into the appliance; or

C.The appliance has been exposed to rain; or

D.The appliance does not appear to operate normally or exhibits a marked change in performance; or

E.The appliance has been dropped, or the enclosure damaged.

16.Servicing - The user should not attempt to service the appliance beyond that described in the operating instructions. All other servicing should be referred to qualified service personnel.

17.Power lines - An outdoor antenna should be located away from power lines.

18.Outdoor Antenna Grounding - If an outside antenna is connected to the receiver, 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, ANSI/NFPA 70 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 electrodes, and requirements for the grounding electrode. See Figure.
