Mighty Mule 352
Powering Options: Transformer or Solar
IMPORTANT:
• The Mighty Mule 352 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 of the
opener arm. The 10 foot harness supplied connects the battery to the master arm.
• The battery charge is maintained by the 18 Volt transformer included or by using optional solar
panel(s). The transformer or solar panel is connected to the opener arm control board using
low voltage, 16 gauge, dual conductor, multi-stranded, direct burial wire (RB509) (see page 24
and the Accessory Catalog).
• All low voltage wire used with the Mighty Mule® 352 Gate Opener must be 16 gauge dual
conductor, multi-stranded, direct burial wire (see page 24 and the Accessory Catalog). Do not
run more than 1000 feet of wire.
• The transformer is designed and intended for indoor use. If the transformer can be plugged
only into an outside electrical outlet, a weatherproof cover or housing (available at local
electrical supply stores) must be used.
• If your gate is more than 1000 ft. from an ac power source, you will need to use at least one
10 watt Solar Panel to charge the battery (see Accessory Catalog). 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 30 watts of solar
charging power. (see Accessory
Catalog). 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.
* Use up to 250 feet of 16 AWG
wire to place solar panel in a
good location.
