NEVER USE TRANSFORMER AND SOLAR PANEL(S) AT THE SAME TIME!
It will damage 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 solar panel to provide an adequate charge through the control board to the battery
at distances up to 250'.
• 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.
Step 1
Make sure the power switch is OFF.
Step 2
Strip 3/16" off the ends of the low voltage wire and twist tightly. Attach
these ends to the 14VAC OR SOLAR terminals located on the terminal
block. Be certain not to let the exposed wires touch each other!
Step 3
Insert one solar panel wire into a 14VAC OR
SOLAR terminal. Insert the other solar panel
wire into the remaining 14VAC OR SOLAR
terminal. The wires can be connected to the
14VAC OR SOLAR terminals regardless of
color/polarity.
Step 4
Tighten set screws against exposed end of wires. A dab of household
petroleum jelly on each terminal will help prevent corrosion.
NOTE: For multiple panels, wire the panels in
parallel as shown in this diagram.
