Mighty Mule 202
Connecting Solar Panel(s)
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 202 to charge the opener battery, skip this section
and go to "CONNECTING BATTERY".
Strip
3
/16" off the ends of the low voltage
wire and twist tightly. Attach these
ends to the '14VAC or SOLAR'
terminals located on the terminal block
(see illustration at right). Be certain not
to let the exposed wires touch each
other!
Insert one solar panel wire into a
'14VAC or SOLAR' terminal. Insert
the other solar panel wire into the
remaining '14VAC or SOLAR'
terminal. The wires can be connected
to the '14VAC or SOLAR' terminals
regardless of color.
Tighten set screws against exposed end of
wires. A dab of household petroleum jelly on
each terminal will help prevent corrosion.
NOTE: For multiple panels wire the panels in
parallel as shown in this diagram.

IMPORTANT INFORMATION ABOUT LOW VOLTAGE WIRE
The only wire acceptable for use with GTO products is 16 gauge multi-stranded, low voltage,
PVC sheathed wire. This particular gauge enables the transformer to provide an adequate
charge through the control board to the battery at distances up to 500 ft.
DO NOT use telephone wire or solid core wire. Unlike multi-stranded wire, these types of wire
are inadequate for use with your gate opener system.
NEVER splice wires together. Splicing permits corrosion and seriously degrades the wire's
ability to carry an adequate current.
