GTO 2550, 2502 installation manual Important Information about LOW Voltage Wire

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 3

Lay the measured length of low voltage wire in a trench following a path the selected electrical outlet to the control box. Wires coming up from ground should be run through PVC conduit to protect them from lawn blades, weed eaters, and grazing animals. Be sure to bury the wire laid trench.

Step 4

Feed the low voltage wires upward through the strain relief opening on lower left of the control box. Pull 6" to 8" of wire into the control box tighten the strain relief screw to secure the 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 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 color.

Tighten set screws against exposed end of wires. A dab of household petroleum jelly on each terminal will help prevent corrosion.
