WARNINGWARNING

This kit is compatible with most 12Vdc LiftMaster® Gate Access Systems. The combination of this kit and a sealed lead-acid (SLA) battery (not provided) enables the operator to function for short durations in temperatures as low as -20 °C. An additional benefit of the kit is extended battery backup time for solar powered applications.

See chart for battery manufacturers.

• Charge ONLY the batteries identified for use with this product in accordance with the instructions and limitations specified in this manual.

• Observe proper polarity orientation between the batteries and charging circuit.

INSTALLATION

The battery box MUST be located close to the gate operator’s control box in an area that is not prone to flooding, hit by gate or knocked over.

1. Place the battery box in the selected site near the control box.

2. Remove the battery box cover. Set the sealed lead-acid battery (not provided) inside the batter y box with the terminals on top.

3. Connect the battery cable to the battery. Attach the ring terminal on the red wire to the positive (+) terminal of the battery. Attach the ring terminal on the black wire to the negative (-) terminal of the battery.

1. Disconnect all power to the gate operator before proceeding.

2. Use a screwdriver to punch out the plastic knockout at the bottom of the control box. Install the water tight connector.

3. Feed the non-connector end of the extension cable through the watertight connector from the inside of the control box. Tighten the watertight connector until the cable is secure.

4. Run the extension cable to the battery box and connect the black wire of the extension cable to the black wire of the terminal block on the battery cable. Connect the white wire to the red wire.

5. Connect the batter y connectors on the control board to the connector on the extension cable in the control box.

NOTE: Disconnect one of the internal 7 AH batteries and use the connector to connect the external battery. The unused 7 AH battery can be removed from the system.

6. Verify that the gate operator operates correctly.

IMPORTANT NOTE: If the gate operator does not operate correctly, the wiring may be incorrect. Also, if the battery has been discharged, disconnect it and charge separately. Refer to troubleshooting for more tips.

7. Use the wire ties to secure the cables.

8. Reconnect power to the operator.

9. Close the cover on the control box.

10. Place the cover on the top of the batter y box. Be sure all drain holes and air vents are properly opened.

1. Wires may be swapped. Verify that all wires are properly connected.

2. Battery is not charged. It is possible that the 12V battery (not provided) was not fully charged when installed. Use a voltmeter to make sure this battery is good and has at least 12V across the open circuit terminals.

3. Blown fuse. It is possible that a fuse, either in the battery cable harness or on the operator control board, may have been blown during the installation. If a blown fuse is found, first check all wiring to make sure it is correct, and then replace the fuse with the same size and type.

1. Wires may not be properly connected. Verify all connections for the installation. Batteries are required for the operator to run.

2. Blown fuse. It is possible that a fuse, either in the battery cable harness or on the operator control board, may have been blown during the installation. If a blown fuse is found, first check all wiring to make sure it is correct, and then replace the fuse with the same size and type.

3. Battery is not charged. It is possible that the 12V battery (not provided) was not fully charged when installed. Use a voltmeter to make sure this battery is good and has at least 12V across the open circuit terminals.

4. Debris or other obstructions are affecting gate travel. Make sure that the battery box and connecting wires are clear of the gate. Clear the gate of all obstructions and verify all safety devices are operating properly.
