1. Route the high voltage 120/230 VAC lines through the earth-grounded conduit fitting on
the left side of the box. The Power Supply Box with a transformer comes with a barrier
that separates the high voltage side on the left, from the low voltage 24 VAC 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 cover door.
3. Attach the supplied 3-pin power plug to the incoming high voltage power wires in the
box. Refer to connector P101 in the table above and to the image below for an illustration
of these connections:
