Powering the System
IMPORTANT:
• The Mighty Mule 350 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 opener 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 (FM509) (
seepage 23 and the
Accessory Catalog
).
• All low voltage wire used with the Mighty Mule® Gate Opener must be 16 gauge dual conductor,
multi-stranded, direct burial wire (
see page 20
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 5 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 5 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.
NOTE
: A maximum of 30 watts of solar
charging power can be connected to the
Mighty Mule® Gate Opener. Consult
