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.

SUPPLYING POWER TO THE UNIT
The TRACER 4206 can operate from a supply between 21 and 63 VDC, with either polarity referenced to
ground. Power supplies should be able to provide up to 30 watts at the selected voltage. A dual pin
terminal plug accepts power at the rear panel of the unit, providing a + and - polarity reference point.
Adapters for this plug are available (P/N 1175043L2) and are furnished with the unit and optional power
supply (P/N 1280650L1).
