GROUNDING INSTRUCTIONS

The following grounding information is from the Underwriters' Laboratory UL60950 Standard for Safety
of Information Technology Equipment Including Electrical Business Equipment, Third Edition,
December 1, 2000.
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 circuit that supplies the product or system. Bare, covered, or
insulated grounding conductors are acceptable. Individually covered or insulated equipment grounding
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 supplemen-
tary 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 connection to ground of the supplementary equip-
ment 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 supplementary equip-
ment grounding conductor is permitted to be made to building steel, to a metal electrical raceway system,
or to any grounded item that is permanently and reliably connected to the electrical service equipment
ground.
The supplemental grounding conductor shall be connected to the equipment using a number 8 ring terminal
and should be fastened to the grounding lug provided on the rear panel of the equipment. The ring terminal
should be installed using the appropriate crimping tool (AMP P/N 59250 T-EAD Crimping Tool or
equivalent.)
