plugged into an outside electrical outlet, a weatherproof cover/housing (available at local 
electrical supply stores) must be used. 
 • TheonlywireacceptableforusewithGTOproductsis16gaugestranded,lowvoltage,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.

 • NEVER USE TRANSFORMER AND SOLAR PANEL(S) AT THE SAME TIME! Doing so will

and Gate Activity Chart on page 2.
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.
