MM272 Installation Instructions

1. Determine Charging Options for Battery: Transformer OR Solar
IMPORTANT
• The Mighty Mule 272 is designed and intended for use with a 12 Volt automotive, marine or lawn tractor battery. The
battery must be placed inside a weatherproof case and located within 6' of the control box.
The 8' battery harness
connects the battery to the control board
.
• The battery charge is maintained by the 16 Volt transformer included
OR
optional solar panel(s). The transformer
OR
solar panel is connected to the control board using low voltage, 16 gauge, dual conductor, multi-stranded, direct burial
wire [RB509] (
)
.
• All low voltage wire used with the Mighty Mule Gate Opener must be 16 gauge dual conductor, multi-stranded, direct
burial wire
.
• The transformer is intended for indoor use. If the transformer can only be plugged into an outside electrical outlet, a
weatherproof cover or housing
must
be used.
• If your gate is more than 1000' from an AC power source, you will need to use a solar panel charging kit (
minimum 10
watts
) . Refer to the Solar Panels and Gate Activity Chart below.
The table and map illustrate the
maximum number of gate cycles
to expect per day in a particular
area when using from 10 to 20 watts of solar
charging power prior to the battery depleting to a
state where the unit will not function. The figures
shown are for winter (minimum sunlight) and do
not account for the use of any accessory items.
Accessories connected to your system will
draw additional power from the battery and
will require additional solar panels.
A deep cycle marine battery is recommended for
solar and/or high traffic applications.
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.
