Step 5
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 
polarity or color.
Tighten set screws against exposed end of wires.

WARNING! DO NOT PLUG THE TRANSFORMER 
INTO AN OUTLET DURING THIS STEP! THE 
TRANSFORMER MUST ONLY BE PLUGGED INTO 
AN OUTLET DURING STEP 7!
Step 3
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 4
Feed the low voltage wire upward 
through the pre-drilled hole in the knock 
out on the bottom of the control box. 
Pull 6" to 8" of wire into the control 
box, enough to reach the Power Input 
on the control board.
IMPORTANT INFORMATION ABOUT LOW VOLTAGE WIRE
The only wire acceptable for use with GTO products is 16 gauge 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 stranded wire, these types of wire are not 
appropiate for use with your gate opener system. 
AVOID splicing wires together. Splicing permits corrosion and seriously degrades the wire's ability to 
carry an adequate current.
