1. Route the high voltage 120/230 VAC wires through the grounded conduit fitting on the
left side of the unit. The unit with a transformer comes with a barrier that separates the
high voltage side on the left, from the low voltage side on the right.
2. Cut and trim the high voltage 120/230 VAC power and ground wires with sufficient slack
to reach their connector terminal in the box, but not so long as to be pinched by or to
obstruct closing the door.
3. Attach the supplied 3-pin power plug to the incoming high voltage power wires in the
unit. Refer to connector P101 in the table above and to the image below:
