(surge protector
not supplied)
Run 1000' (max.) of low
voltage wire to control
board from transformer
(wire not included).
PVC conduit (not included)
to protect wire from lawn
mowers and weed eaters.
Step 5
Select the 120 Volt electrical outlet into which you will plug the transformer. Lay the low voltage wire in a trench
following a path from the selected electrical outlet to the opener arm. Wires coming up from the ground should
be run through PVC conduit to protect them from lawn mowers, weed eaters, and grazing animals. Be sure to
bury the wire laid in the trench.
Step 6
Bring enough wire up through
the PVC conduit to allow for
gate movement from open to
closed position. See example
at right.
IMPORTANT INFORMATION ABOUT LOW VOLTAGE WIRE
The only wire acceptable for use with GTO products is 16 gauge dual conductor, stranded,
direct burial wire. This particular gauge enables the transformer to provide an adequate charge
through the control board to the battery at distances up to 1000 ft.
DO NOT use telephone wire or solid core wire. Unlike stranded wire, these types of wire are
inadequate for use with your gate opener system.
NEVER SPLICE WIRES . Splicing permits corrosion and seriously degrades the wire's
ability to carry an adequate current.
IMPORTANT: Never connect the transformer and a solar panel to the opener control board at the same time. It
will damage the control board.
IMPORTANT: If you are using SOLAR PANEL(S) to charge the opener battery, skip this section and
go to "Connecting Solar Panel(s)" section on page 23.
