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.

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.)

•
This unit shall be installed in accordance with Article 400 and 364.8 of the NEC NFPA
70 when installed outside of a Restricted Access Location (i.e., central office, behind a
locked door, service personnel only area).
•
Power to the TRACER 4108/4208 DC system must be from a reliably grounded
21-60 VDC source which is electrically isolated from the AC source.
•
The branch circuit overcurrent protection shall be a fuse or circuit breaker rated
minimum 60 VDC, maximum 10A.
•
A readily accessible disconnect device that is suitably approved and rated shall be
incorporated in the field wiring.
