SAFETY IMPORTANT SAFETY INFORMATION INSTALLATION IMPORTANT SAFETY INFORMATION To prevent SERIOUS INJURY or DEATH from a moving gate: • Pinch points must be guarded at all times. Install enclosed-style gate tracks and roller guards. • Place screen mesh 4 feet (1.2 m) high on the gate to prevent access through openings anywhere the gate may travel. • Mount controls at least 6 feet (1.8 m) from the gate or ANY moving part of the gate. • Install Warning signs on EACH side of gate in PLAIN VIEW. Permanently secure each Warning sign in a suitable manner using fastening holes. • This operator is intended for vehicular use only. To prevent INJURY to pedestrians, a separate pedestrian access should be supplied, visible from the gate. Locate the pedestrian access where there is not a chance of INJURY at any point during full movement of the gate. • Contact sensors MUST be located at the leading and trailing edges, and post mounted both inside and outside a horizontal swing gate. Non-contact sensors such as photo eyes MUST be mounted across the gate opening and operate during BOTH the open and close cycles. • Entrapment protection devices MUST be installed to protect anyone who may come near a moving gate. • Locate entrapment protection devices to protect in BOTH the open and close gate cycles. • Locate entrapment protection devices to protect between moving gate and RIGID objects, such as posts or walls. • Too much force on gate will interfere with proper operation of safety reversal system. • NEVER increase force beyond minimum amount required to move gate. • NEVER use force adjustments to compensate for a binding or sticking gate. • If one control (force or travel limits) is adjusted, the other control may also need adjustment. • After ANY adjustments are made, the safety reversal system MUST be tested. Gate MUST reverse on contact with a rigid object. • DO NOT touch the heater when switch is on, heater may be hot. • To AVOID damaging gas, power or other underground utility lines, contact underground utility locating companies BEFORE digging more than 18 inches (46 cm) deep. WIRING • ALWAYS wear protective gloves and eye protection when changing the battery or working around the battery compartment. 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. ADJUSTMENT • 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. To reduce the risk of SEVERE INJURY or DEATH: • Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a moving gate. • Too much force on gate will interfere with proper operation of safety reversal system. • NEVER increase force beyond minimum amount required to move gate. • NEVER use force adjustments to compensate for a binding or sticking gate. • If one control (force or travel limits) is adjusted, the other control may also need adjustment. • After ANY adjustments are made, the safety reversal system MUST be tested. Gate MUST reverse on contact with a rigid object. 6
