The mating plug is fastened by turning the coupling nut clockwise 1/4 turn by
hand until it 'clicks' into the locked position. To remove the power plug, twist the
coupling nut counter-clockwise 1/4 turn.
The Installer must assemble the cable on site in a length ordered according to the
site requirement. Use cable type SOOW, 8 AWG (min.), 2-conductor (8/2),
shielded, stranded copper wires, indoor/outdoor, round cable, cable
OD 0.28–0.67 in (7–17 m), rated at 600 V, or equivalent. Cable can be a
maximum of 328 ft (100 m) in length. The Installer is responsible for determining
the power interface requirements at the supply-side of the cable and orders and
installs the required connector, if any.
