External television antenna grounding

If an outside antenna or cable system is to be connected to your eMachines PC, make sure that

the antenna or cable system is electrically grounded to provide some protection against voltage

surges and static charges.
Article 810 of the National Electrical Code, ANSI/NFPSA 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.
Cable distribution system should be grounded (earthed) in accordance with ANSI/NFPA 70, the

National Electrical Code (NEC), in particular Section 820.93, Grounding of Outer Conductive Shield

of a Coaxial Cable.

Lightning protection

For added protection of any eMachines product during a lightning storm or when it is left

unattended or unused for long periods of time, unplug the product from the wall outlet and

disconnect the antenna or cable system.

Important

The instructions are for the person who installs cable to the system.

eMachines assumes you are qualified in the servicing of computer equipment
and trained in recognizing hazards in products with electric shock.
