Additionally, there are four buttons on the top of the Electronics Box which allow one to manually move the
linear actuators in the north, south, east and west directions. See Figure 2 below.

WARNING: Do NOT connect the SunTura Solar Tracker electronics to the power supply until you
have completely finished the installation process and all people are safely away from the solar
tracker’s range of motion!
The red and black wires coming out of the Electronics Box are the power supply wires. These wires need to
be connected to a 12 or 24 volt DC power supply. Some good examples of power supplies are a 12 volt
battery, a 24 volt battery or a 12/24 VDC power supply that plugs into an AC wall outlet. The DC power
supply must be able to supply a minimum of 4 amps.
Additionally, the DC power supply can NEVER
exceed 30 volts DC or the SunTura Solar Tracker electronics will be permanently destroyed. Even if
the voltages exceeds 30 VDC for only just an instant, the electronics will be permanently destroyed! Windy
Nation Inc. recommends a car sized 12 volt battery to power the SunTura Solar Tracker electronics. The red
wire coming out of the Electronics Box connects to the positive output of the DC power supply. The black
wire coming out of the Electronics Box connects to the negative output of the DC power supply. See Figure 3
below.

3.2.2 North/South Linear Actuator Installation
The North/South linear actuator has a stroke length of six inches (the shorter of the two linear actuators
included in the kit) and has two 5/16 inch diameter mounting holes. It is wired to the SunTura Tracking
Electronics in the following manner: If the sun is located to the north of the solar tracker, the north/south
linear actuator will extend so it positions the solar panels perpendicular to the sun’s light rays. If you wish for
the north/south linear actuator to retract when the sun is to the north of the solar tracker, then you can simply
switch the green and blue wires that are connected to the north/south linear actuator.
