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 50 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.
Battery Safety
 Do NOT let the positive (+) and negative (-) terminals of the battery touch each other.
 Use only sealed lead-acid, flooded, or gel batteries which must be deep cycle.
 Explosive battery gases may be present while charging. Be certain there is enough
ventilation to release the gases.
