1. Determine Charging Option for Battery: Transformer OR Solar
IMPORTANT:
¾ The Mighty Mule gate operator is designed and intended for use with a 12 Volt automotive or marine type battery. The
battery must be placed inside a weatherproof case and located within 6 feet from the Control Box. The 8 foot harness
supplied connects the battery to the Control Box.
¾ The transformer is designed for indoor use. If the transformer can be plugged only into an outside electrical outlet, a
weatherproof cover/housing (available at local electrical supply stores) must be used.
¾ If your gate is more than 1000 ft. from an AC power source, you will need to use at least 10 watt solar charging power
to charge the battery [FM123]. Refer to the Solar Panel and Gate Activity chart below.
¾ All low voltage wire used with the Mighty Mule gate operator must be 16 gauge dual conductor, stranded, direct burial
wire [RB509]. Do not run more than 1000 ft. of wire.
NEVER USE TRANSFORMER AND SOLAR PANEL(S) AT
THE SAME TIME. It will damage the control board.
The table and map illustrate
the maximum number of gate
cycles to expect per day in a
particular area when using
from 10 to 30 watts of solar
charging power prior to the
battery depleting to a state
where the unit will not function. The gures shown
are for winter (minimum sunlight). Accessories
connected to your system will draw additional
power from the battery.
NOTE: UP to 250 ft. of dual conductor, 16 gauge,
multi-stranded wire may be used to allow installation
of solar panels in direct sunlight.
10 Watt Solar Panel [FM123]
Deep cycle marine battery is recommended for
solar and/or high trafc applications.
