Connect the Power Input
IMPORTANT:
•The transformer is designed and intended for indoor use. If the transformer can only be plugged into an outside electrical outlet, a weatherproof cover/housing (available at local electrical supply stores) must be used.
•The only wire acceptable for use with GTO products is 16 gauge stranded, low voltage, direct burial wire 
[RB509]. This 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 wire.
•NEVER SPLICE WIRES. Splicing permits corrosion and seriously degrades the wire’s ability to carry an adequate current.
•NEVER USE TRANSFORMER AND SOLAR PANEL(S) AT THE SAME TIME! Doing so will damage the control board.
•If your gate is more than 1000 ft. from an AC power source, you will need to use at least 10 watts solar charging power 
[FM122/FM123] to charge the battery. Refer to the Solar Panels and Gate Activity Chart on page 2.
ON/OFF Switch |
Step 1
Make sure the control box power switch is OFF.
Step 2
Select the electrical outlet outlet into which you will plug the transformer. Measure the distance from this outlet to the control box following the path where the wire will be laid (allow for an additional 6” to be pulled into the control box).
Step 3
Lay the 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. Bury the wire in the trench.
Step 4
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.
