Wall or Ceiling Mounting - The unit should be mounted to a
wall or ceiling only as recommended by the manufacturer.
Heat - The product should be situated away from heat sources
such as radiators, heat registers, stoves, or other products
(including amplifiers) that produce heat.
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. Article 810 of the
National Electrical Code, ANSI/NFPA 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.
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 shall be connected to the grounding system of the
building, as close to the point of cable entry as practical.
