IMPORTANT SAFEGUARDS
11A A product and cart combination should be moved with care. Quick stops, excessive force, and
uneven surfaces may cause the product and cart combination to overturn.
12 Outdoor Antenna Grounding—If an outside antenna or cable system is connected to the product, be
sure the antenna or cable 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 No. 70-1984 (Section 54 of
Canadian Electrical Code, Part 1) 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 following example.
Example of Antenna Grounding

13 Power Lines — An outside antenna system should not be located in the vicinity of overhead power lines,
other electric light 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 or approaching such
power lines or circuits as contact with them might be fatal. Installing an outdoor antenna can be hazardous
and should be left to a professional antenna installer.
