GROUNDING INSTRUCTIONS
The following paragraphs provide grounding instruction information from the Underwriters’ Laboratory 
UL60950 Standard for Safety of Information Technology Equipment Including Electrical Business 
Equipment, with revisions dated March 15, 2002.
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 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 connection 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 supplementary equipment 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).
The supplemental equipment grounding terminal is located on the rear panel of the
