Step 23
Lay the measured length of low voltage wire in a
trench following a path from the selected electrical
outlet to the control box. Wires coming up from the
ground should be run through PVC conduit to protect
them from lawn mower blades, weed eaters, and
grazing animals. Be sure to bury the wire laid in the
trench.
Step 24
Feed the low voltage wires upward through the strain
relief opening on the lower left of the control box. Pull
6" to 8" of wire into the control box and tighten the
strain relief screw to secure the wires.
IMPORTANT INFORMATION ABOUT LOW VOLTAGE WIRE
The only wire acceptable for use with GTO products is 16 gauge multi-stranded, low voltage, PVC
sheathed 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 multi-stranded wire, these types of wire are
inadequate for use with your gate opener system. Telephone wire and solid core wire do not deliver
enough voltage for your gate opener to function and will cause the system to go into a condition known
as "low voltage lockout."
Never splice wires together. Splicing permits corrosion and seriously degrades the wire's ability to carry
an adequate current.
Step 25:
Strip 3 / 16 " off the ends of the low voltage wire and twist
tightly. Attach these ends to the 18VAC terminals located
on the POWER IN terminal block (see illustration at
right). Be certain not to let the exposed wires touch
each other!
Insert one transformer wire into an 18VAC terminal.
Insert the other transformer wire into the remaining
18VAC terminal. The transformer wires can be connected
to the 18VAC terminals regardless of color.
Tighten set screws against exposed end of wires. A dab of
household petroleum jelly on each terminal will help
prevent corrosion.
