General Safety Information
• Read all of the instructions and cautions in the manual before beginning the
installation.
• There are no serviceable parts for this controller. Do NOT disassemble or attempt
to repair the controller.
• Make sure all connections going into and from the controller are tight. There may
be sparks when making connections, therefore, make sure there are not flammable
materials or gases near installation.
Charge Controller Safety
• NEVER connect the solar panel array to the controller without a battery. Battery
must be connected first. This may cause a dangerous occurrence where the
controller would experience a high open circuit voltage at the terminals.
• Ensure input voltage does not exceed 25 VDC to prevent permanent damage. Use
the Open Circuit (V
oc
) to make sure the voltage does not exceed this value when
connecting panels together in series.
• The charge controller should be installed indoors in a well-ventilated, cool, and dry
environment.
• Do NOT allow water to enter the controller.
