CONNECT SOLAR PANEL(S) TO OPERATOR
CONTROL BOX
Open the control box cover.
Disconnect all power and batteries from the control board.
Run the solar panel cable to the bottom of the control box. Thread the cable
through the watertight connector and pull the cable through until it reaches the
AC PWR/SOLAR connector on the control board.
Tighten the watertight connector on the cable.
Attach the solar panel wires to AC PWR/SOLAR input terminal (polarity is
not important). Leave the AC PWR/SOLAR earth ground connection open.
With the batteries still disconnected, the control board should power up if the
solar panel is correctly installed and the sun is shining (the diagnostic LED will
blink).
NOTE: The system is designed to be charged by either an AC plug-in transformer or
a separate solar panel, but not both.
Use the cable ties to secure the solar panel cable away from places where it
could be damaged.
NOTE: If the sky is too overcast to allow the solar panel to power up the system,
the panel will need to be verified at another time when the sun is shining. There is no
other way to verify the panel installation.

CONNECT BATTERIES
The batteries are charged in circuit by using the solar panel (provided).
Locate the two white battery plugs on the left-hand side of the control box.
Connect the plug from the battery to connector on the control board.
NOTES: Batteries will degrade over time depending on temperature and usage. For
best performance, the batteries should be replaced every 3 years. Batteries do not
perform well in extremely cold temperatures.
