Route power-supply cords so they are not
likely to be walked on or pinched by items
placed upon or against them, paying particu-
lar attention to cords at plugs, convenience
receptacles, and the point where they exit

National Electrical Code (USA), ANSI/NFPA
70, provides information on grounding of the
mast and supporting structure, grounding of
the lead-in wire to an antenna discharge unit
connection to the grounding electrodes, and
requirements for the grounding electrode.
(See Figure.1 on reverse side for an example).
15. Lightning
For added protection for this product during
a lightning storm, or when product is left
unattended and unused for long periods of
time, unplug it from the wall outlet and
disconnect antenna or cable system. This
will prevent damage to product due to
lightning and power line surges.
