POWER WIRING

This operator can be wired for either 120 Vac (standard) 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 or mount
the receiver away from the operator to avoid interference with the operator.
