Wiring the 120 Vac/240 Vac Model

SHOCK HAZARD: To avoid electrical shock, do not connect wires when
the circuits are energized.
To extend wire for the power connections, use only 12 AWG
to 18 AWG (2.5 mm
connector must be suitably protected to prevent damage. Use
grommets, bushings, and wires ties to protect them from abrasion.
To wire the 120 Vac or 240 Vac Model eHorn:
1.
Strip no more than 0.25 inch (6 mm) of wire insulation from
the ends of the power leads. If you are using stranded wire, be
sure there are no loose strands outside the connector plug that
could touch the adjacent lead and cause a short circuit. Torque
the terminal screws to 4.4 in‑lb (0.5 Nm) maximum.
2.
Connect the power source hot, neutral, and earth ground wires
as shown in Figure 6.
