GROUNDING INSTRUCTIONS
This section provides grounding instruction information from the Underwriters'
Laboratory UL 1459 Standard for Safety: Telephone Equipment, of September 20,
1993.
An equipment grounding conductor that is not smaller in size than the
ungrounded branch-circuit supply conductors is to be installed as part of the cir-
cuit that supplies the product or system. Bare, covered, or insulated grounding
conductors are acceptable. Individually covered or insulated equipment ground-
ing conductors shall have a continuous outer finish that is either green, or green
with one or more yellow stripes. The equipment grounding conductor is to be
connected to ground at the service equipment.
The attachment-plug receptacles in the vicinity of the product or system 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 supplementary equipment grounding conductor shall be installed between the
product or system and ground that is in addition to the equipment grounding
conductor in the power supply cord.
The supplementary equipment grounding conductor shall not be smaller in size
than the ungrounded branch-circuit supply conductors. The supplementary
equipment grounding conductor shall be connected to the product at the terminal
provided, and shall be connected to ground in a manner that will retain the
ground connection when the product is unplugged from the receptacle. The con-
nection to ground of the supplementary equipment grounding conductor shall be
in compliance with the rules for terminating bonding jumpers at Part K or Article
250 of the National Electrical Code, ANSI/NFPA 70. Termination of the supple-
mentary equipment grounding conductor is permitted to be made to building
steel, to a metal electrical raceway system, or to any grounded item that is perma-
nently and reliably connected to the electrical service equipment ground.
Bare, covered, or insulated grounding conductors are acceptable. A covered or
insulated grounding conductor shall have a continuous outer finish that is either
green, or green with one or more yellow stripes.
