Step 7
Plug the transformer into the electrical outlet.
(Use of a surge protector with the transformer is
strongly recommended.)
HINT: Keep a few mothballs in the control box to
discourage insects from entering it and damaging the
control board.
NOTE: If transformer will be located outside be sure
to enclose in a weatherproof cover (not included).
Step 6
Strip
1
/2" of insulation from the ends of the low voltage wire. Attach these stripped ends to the
transformer terminals.
A dab of household petroleum jelly on each terminal will help prevent corrosion.
Make sure the exposed wires do not touch each other!

IMPORTANT: Never connect the transformer and a solar panel to the opener control board at the same
time. It will damage the control board.
If you are using the transformer included with the Mighty Mule Gate Opener to charge the opener battery, skip
this section and go to "CONTROL BOARD SETTINGS" below.
Strip
3
/16" off the ends of the low voltage wire from the
solar panel and twist tightly. Insert these ends to the 18
VAC terminal block located on the control board (see
illustration at right). The wires can be inserted into either
terminal regardless of color. Be certain not to let the
exposed wires touch each other!
Tighten set screws against exposed end of wires.
NOTE: For multiple panels wire the panels in parallel as
shown in this diagram.
