Antenna Grounding According to the National Electrical Cord
Overloading - Do not allow anything to rest on the power
cord. Do not overload wall outlets and extension cords
because this can result in fire or electric shock. Do not place
the unit in an area where people will walk on the cord.
Outdoor Antenna
Power lines - An outside antenna system should not be
located in the vicinity of overhead power lines or other
electric light or power circuits, or where it can fall onto such
power lines or circuits. When installing an outside antenna
system, extreme care should be taken to avoid touching
power lines or circuits because contact with them may be
fatal.
Outdoor Antenna Grounding - If an outside antenna or
cable system is connected to the unit, 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, 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. See the figure.
Lightning
For added protection during a lightning storm, or when left
unattended and unused for long periods of time, unplug the
unit from the wall outlet and disconnect the antenna or cable
system. This will prevent damage to the unit due to
lightning and powerline surges.
Maintenance
Cleaning - Unplug the unit from the wall outlet before
cleaning. Do not use liquid cleaners or aerosol cleaners.
Use a damp cloth for cleaning.
Damage Requiring Service
Unplug the unit from the wall outlet and refer servicing to
qualified service personnel under the following conditions:
1) When the power cord or plug is damaged or frayed.
2) If liquid has been spilled into the unit.
3) If the unit has been exposed to rain or water.
4) If the unit does not operate normally when following
the operating instructions. Adjust only those controls
that are covered by the operating instructions because
improper adjustment of other controls may result in
damage to the unit and will often require extensive
work by a qualified technician to restore the unit to
normal operation.
5) If the unit has been dropped or the cabinet has been
damaged.
6) When the unit exhibits a distinct change in
performance - this indicates a need for service.
Do not attempt to service the unit yourself because opening
or removing covers may expose you to high voltage or other
hazards. Refer all servicing to qualified service personnel.
Replacement Parts - When replacement parts are required,
be sure the service technician has used replacement parts
specified by the manufacturer or having the same
characteristics as the original part. Unauthorized
substitutions may result in fire, electric shock or other
hazards.
Safety Check - After completion of any service or repairs to
the unit, ask the service technician to perform a safety
check to ensure that the unit is in proper operating
condition.
Note to CATV system installer:
This reminder is provided to call the CATV system installer’s
attention to Article 820-40 of the NEC that provides
guidelines for proper grounding and, in particular, specifies
that the cable ground should be connected to the grounding
system of the building, as close to the point of cable entry as
practical.
