WIRING POWER WIRING CONTINUED... SOLAR PANEL(S) NOT PROVIDED. SEE ACCESSORIES. The solar panel(s) must be located in an open area clear of obstructions and shading for the entire day. The gate operator is not supported in northern climates where temperatures reach below -4˚F. This is due to cold weather and a reduced number of hours of sunlight during the winter months. Cycle rate may vary from solar chart for areas that reach below 32˚F. Solar panels should be cleaned on a regular basis for best performance to ensure proper operation. For solar applications, a minimum of two 10W solar panels in series and two 7AH batteries are recommended. For Zone 3 cold weather sites, two 33AH batteries are recommended (for Large Metal Control Box (XLM) ONLY). We recommend LiftMaster low power draw accessories to minimize power draw, refer to accessory page. We recommend disconnecting the expansion board for greater cycle ratings and standby time for solar applications. NOTE: Solar power maximum is 24 Vdc at 50 watts maximum. 1 Locate the solar/charge plug on the control board and remove the transformer wires from the plug. 2 Connect the red wire (+) from one solar panel to the black wire (-) of the other solar panel. 3 Connect the remaining red (+) wire from one solar panel to the solar/charge plug (+) on the control board. 4 Connect the remaining black (-) wire from the other solar panel to the solar/charge plug (-) on the control board. 5 Plug in the solar/charge plug.
