under overhead plumbing, sprinkler system valves, or in areas that are
susceptible to flooding.
Lighting: Sufficient lighting is required for testing and maintenance.
Lightning Protection/Grounding: The system must be properly grounded to
protect from lightning damage. The following UL conditions must be met to
ensure proper grounding. (For grounding instructions, see page 3-5.)
• Supplemental and independent equipment grounding conductors are to be
installed between the system and the wiring system ground.
• One of the equipment grounding conductors must be a conductor that is as
large or larger than the ungrounded branch-circuit supply conductors. The
equipment grounding conductor is to be installed as part of the circuit that
supplies the system and is to be connected to ground at the service
equipment. Bare, covered, or insulated grounding conductors are acceptable.
Individually covered or insulated grounding conductors should have a
continuous outer finish that is either green or green with one or more yellow
stripes. The equipment grounding conductor should be connected to ground
at the service equipment.
• The other equipment grounding conductor shall comply with the general
rules for grounding contained in Article 250 of the National Electric Code,
NFPA 70, but its connection to ground shall not depend on the cord and plug
of the system.
• The attachment-plug receptacles of the same type as that used by the
systems that are in the vicinity of the DBS are all to be of a grounding type,
and the equipment grounding conductors serving these receptacles are to be
connected to earth ground at the service equipment.
• A marking adjacent to the telecommunications jacks must instruct the user
to connect a supplementary equipment grounding conductor before any
telecommunication lines are connected to the product or system.
Cleaning
• Use a slightly damp cloth to clean the phones. The phones should never be
cleaned with benzene, paint thinner, or other solvents.
