anapprovedpowercordwith three conductors and a plug
with three terminals. Connect the plug to a receptacle that
has three holes and is connected to the electrical ground.
Thegreen (or green andyellow) conductor in thecord is the
groundwire. Never connect this wireto any terminal other
thantheground pin terminal.
DANGER: Improper connection of
the equipment-grounding conductor can result
in risk of electric shock. Check with a qualified
