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 21 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 21
Make sure the power switch is OFF
before proceeding to the next step.
Step 22
Select the electrical outlet into which 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 one to three GTO
5 watt solar panels (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 three solar panels
can be connected to the Mighty Mule Gate
Opener
®
. Consult Solar Panel Installation
Instructions.
