technician must perform safety checks to determine that this product is
in proper operating condition.
Outdoor Grounding System
If this product connects to an outdoor antenna or cable system, be sure
the antenna or cable system is grounded (earthed). This provides some
protection against voltage surges and built-up static charges.
Article 810 of the National Electric Code (NEC) ANSI/NFPA
No. 70-1990, provides the following information:
• Grounding of the mast and supporting structure
• Grounding the lead-in wire to an antenna discharge unit
• Size of the grounding conductors
• Location of the antenna-discharge unit
• Connection to grounding electrodes
• Requirements for the grounding electrodes (see the following
antenna grounding diagram as recommended by NEC
ANSI/NFPA 70)
Lightning
For added protection for this product 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 or cable system. This will prevent
damage to the product due to lightning and power-line surges. Plugging
this product into a surge protector may reduce the risk of damage.
Note: Unplugging this product for an extended period of time can result
in loss of authorization. For reauthorization, contact your cable service
provider.
Power Lines
WARNING: To avoid electric shock, do not locate an
outside antenna system in the vicinity of overhead power lines or
power circuits.
Do not locate an outside antenna system in the vicinity of overhead
power lines or power circuits. When installing an outside antenna system,
take extreme care to keep from touching power lines or circuits, as
contact might be fatal.
