POWER WIRING

This operator can be wired for either 120 Vac or 240 Vac or a solar
panel (not provided). Follow the directions according to your application.
For dual gate applications, power will have to be connected to each
operator. Main power supply and control wiring MUST be run in
separate conduits.
NOTE: If using an external receiver use shielded wire for the connections and
mount the receiver away from the operator to avoid interference with the operator.
240 VAC ONLY
If using the 240 Vac option a heater cannot be used. The accessory outlet is disabled
and cannot be used with the 240 Vac option.
