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:
• 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.
To reduce the risk of SEVERE INJURY or DEATH:
• BEFORE installing power wiring or control stations be sure to follow ALL
specifications and warnings described below.
• ANY maintenance to the operator or in the area near the operator MUST NOT
be performed until the batteries are disconnected. Upon completion of
maintenance the area MUST be cleared and secured, at that time the unit
may be returned to service.
• 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.
To AVOID damaging gas, power or other underground utility lines, contact
underground utility locating companies BEFORE digging.
WIRING
To avoid SERIOUS INJURY or DEATH:
• Disconnect ALL electric and battery power BEFORE performing ANY service or
maintenance.
• DO NOT connect solar panel(s) when power supply is connected.
• DO NOT connect more than 30W (3 solar panels).
To reduce the risk of FIRE or INJURY to persons use ONLY LiftMaster part
29-NP712 for replacement batteries.
SOLAR PANEL INSTALLATION
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.
