Install Wiring Harness and Battery
The recommended battery for most installations is a 12 volt Group
U1 maintenance free battery, 30 to 35 amp hours. This type battery is
commonly known as a lawn tractor or wheel chair battery.
The wire harness is supplied with two ¼” ring terminals for connection to
the battery. Connect the wire harness red wire to the positive post of the
battery and the wire harness black wire to the negative post of the battery
as shown.
Connect the actuator 2 wire connector (or connectors if dual gate) to wire
harness as seen in the image here.
Plug the J2 accessory plug into the control board at this time.
Install Battery Controller Power Source (AC or Solar)
The USAutomatic battery controller can be powered by an DC transformer supplied with AC Models
OR a solar panel supplied with Solar models. The DC Transformer and the Solar Panel are equipped
with a DC plug for easy connection to the battery controller.
AC Charged System
The AC model gate operator comes with a low voltage transformer which plugs
into the battery controller and can easily provide 575 cycles of operation a
day without decreasing the battery charge. In the event AC power goes out
the operator will operate for weeks on the battery (if cycles per day are below
20) before needing service. Accessories connected to the operator are critical.
Always use Solar Friendly accessories to help avoid premature battery failure in
cases of power outages.
The unique design of the charging system allows the transformer to be installed away from the gate
area if needed. This means that on AC charged systems, the transformer’s low voltage wire can be
extended avoiding the expense of having an electrician install 120 VAC at the gate area.
Refer to the AC power source cable extension chart in Appendix A for wire size.
NOTE: Transformer is not designed to get wet. Likewise, all splices should be made in a dry
enclosure or outdoor box. For convenience use the USAutomatic Charge Cable Extension Pigtails
PN #630038.
NOTE:
USAUTOMATIC RECOMMENDS A SURGE PROTECTOR ON ALL AC
CHARGED INSTALLATIONS.
