Powering the System
Installation of the Transformer
IMPORTANT:
• 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.
• 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.
• 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.
Step 1
Make sure the power switch is OFF before proceeding to the next step.
Step 2
Select the electrical outlet iwhere you will plug the transformer.
Measure the distance from this outlet to the control box following the
path where the wire will be laid. After you have measured how much
wire is needed, cut the wire to the appropriate length.
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.
NOTE: A maximum of 30 watts of solar
charging power can be connected to the
Mighty Mule® Gate Opener. Consult Solar
Panel
