3.0 Warnings
• WARNING: DO NOT REMOVE PROTECTIVE CARDBOARD ON SOLAR PANEL UNTIL THE SOLAR PANEL IS
INSTALLED AND WIRED TO THE CONTROLLER. The solar panel is an energy source. Once cables are attached
to it and the panel exposed to a light source the cables become live. Bare or exposed copper conductors can
short during wire preparation & routing creating hazardous sparks and possible damage to solar panel. Leave
protective cardboard in place until installation is 100% complete.
• Warning: Be very careful when working with batteries. Lead acid batteries can generate explosive gasses
and short circuits can draw thousands of amps from the battery. Read these instructions and those included
with the charge controller and battery.
• DO NOT exceed the voltage or current ratings of the controller. Use only with a 12 volt battery.
• DO NOT short circuit the PV array or load while connected to the controller. This will DAMAGE the
controller.
• The controller should be protected from direct sunlight. Ensure adequate space for air flow around the
controller
• The negative system conductor should be properly grounded.

5.0 Installation Overview/Planning
A. Solar Panel Wiring
• Review the system diagram on the following page (Figure 1) and determine best location for the solar
panel, charge controller and a convenient wiring location to connect to the vehicle battery system.
• Please note, the solar panel and mounting brackets will increase vehicle clearance requirements by
approximately 3" if mounting panel to the highest location on the vehicle. Personnel operating vehicle should
be made aware of increased vehicle height clearance requirements.
