● 12 Volt automotive or marine battery and a
weather proof case.
● Low voltage wire will be needed to run from
the transformer to the control box; length
depends upon the distance between the
transformer power supply and the control box.
See Transformer Wiring Installation on
,
and the accessory catalog.
● PVC conduit.
● If your gate is more than 1000' away from an
AC power source you will need to use at least
one Mighty Mule solar panel to trickle charge
the battery. See the accessory catalog (Do not
use both transformer and solar).
● If you have thin-walled tube or panel gates, see
Recommended Reinforcement Examples after
Step 3 of “Mounting Operator to Gate”.
● Depending on the type of gate, a horizontal
cross member or mounting plate may be
needed to mount the front of the operator and
gate bracket to the gate. See Gate Bracket
Mounting Examples after Step 3 of “Gate
Operator Installation.”
● Surge protection for transformer.
● Some types of installations require u-bolts.
● Additional washers or a metal plate may be
needed for wooden post.
● Weatherproof cover for outdoor outlet and
transformer.
● If the post is larger than 6”, bolts longer than
8” are needed.

Swing gate and operator arm to the CLOSED position-check
clearance/binding by inspecting alignment. Arm stroke should be a
maximum of 13”.
TIP: Turning the pivot bracket over gives more
hole alignment options for the post pivot bracket assembly.
