3.2.1 Electronics Box Installation
The Electronics Box has a 20 amp fuse on the circuit board located on its inside. There is also one additional
spare fuse. The fuse protects the SunTura Solar Tracker electronics from a short circuit. If you accidentally
short circuit the electronics, simply replace the blown fuse with the spare fuse. Do NOT bypass the fuse.
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.
Figure 2: Electronics Box manual controls and fuse locations.
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 through 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 12 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 or 18 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
(Note: The North/South linear actuator is only included in the Dual Axis Kit. If you purchased the Single Axis
Kit, then skip section 3.2.2 and proceed to section 3.2.3)
The North/South linear actuator has a stroke length of 18 inches (the shorter of the two linear actuators
included in the kit). It will be wired to the SunTura Tracking Electronics in the following manner: If the sun is
