INSTALLATION To reduce the risk of SEVERE INJURY or DEATH: • ANY maintenance to the operator or in the area near the operator MUST NOT be performed until disconnecting the electrical power (AC or solar and battery) and locking-out the power via the operator power switch. Upon completion of maintenance the area MUST be cleared and secured, at that time the unit may be returned to service. • Disconnect power at the fuse box BEFORE proceeding. Operator MUST be properly grounded and connected in accordance with national and local electrical codes. NOTE: The operator should be on a separate fused line of adequate capacity. • ALL electrical connections MUST be made by a qualified individual. • DO NOT install ANY wiring or attempt to run the operator without consulting the wiring diagram. We recommend that you install an edge sensor BEFORE proceeding with the control station installation. • ALL power wiring should be on a dedicated circuit and well protected. The location of the power disconnect should be visible and clearly labeled. • ALL power and control wiring MUST be run in separate conduit. STEP 8 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. SOLAR APPLICATIONS: For solar applications refer to Solar Panels section in the Appendix, pages 45-48. Follow the directions according to your application. 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.
