specified. For terminal markings, internal wiring and contact arrangements refer to wiring diagram above. Use solid or stranded COPPER wire with insulation to suit installation. See
table for gauge selection.
To make power connections remove 1/2 inch of insulation from wire ends. Insert bare ends
of wire under the pressure plate of terminals. Use 3/16 or larger screw driver to tighten
terminal screws firmly.
