SAFETY » IMPORTANT SAFETY INFORMATION INSTALLATION To prevent SERIOUS INJURY or DEATH; one or more non-contact sensors shall be located where the risk of entrapment or obstruction exists. To prevent SERIOUS INJURY or DEATH from a moving gate: • 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. • A swinging gate shall NOT open into public access ways. To prevent SERIOUS INJURY or DEATH from a moving gate: • Install warning signs on the front and back of the gate in PLAIN VIEW. • Permanently secure each warning sign in a suitable manner using fastening holes. ALWAYS wear protective gloves and eye protection when changing the battery or working around the battery compartment. • DO NOT use flooded lead acid battery. • Flooded lead acid batteries will produce gases when discharging and recharging which can explode. • DO NOT dispose of battery in fire. Battery may explode. Check with local codes for disposal instructions. WIRING 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 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 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 optional reversing edge 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. • BEFORE installing power wiring or control stations be sure to follow ALL specifications and warnings described below. Failure to do so may result in SEVERE INJURY to persons and/or damage to operator. To AVOID damaging plug-in transformer, it MUST be enclosed in a suitable weatherproof enclosure and provided with proper weatherproof fixtures. To AVOID damaging gas, power or other underground utility lines, contact underground utility locating companies BEFORE digging. To reduce the risk of FIRE or INJURY to persons use only LiftMaster part #K74-30762 for replacement batteries. ADJUSTMENT Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing gate. • Too much force on gate will interfere with proper operation of safety reversal system. • NEVER increase force beyond minimum amount required to close 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. 5
