Please read these instructions before installing or operating the Charge Controller to prevent per-
sonal injury or damage to the Charge Controller.
General
Installation and wiring compliance
• Installation and wiring must comply with the local and National Electrical Codes and must
be done by a certied electrician.
Preventing electrical shock
• The negative system conductor should be properly grounded. Grounding should comply
with local codes.
• Disassembly / repair should be carried out by qualied personnel only.
• Disconnect all input and output side connections before working on any circuits
associated with the Charge Controller. Turning the on/off control on the Charge
Controller to off position may not entirely remove dangerous voltages.
• Be careful when touching bare terminals of capacitors. The capacitors may retain high
lethal voltages even after the power has been removed. Discharge the capacitors before
working on the circuits.
Installation environment
• The Charge Controller should be installed indoor only in a well ventilated, cool, dry
environment.
• Do not expose to moisture, rain, snow or liquids of any type.
Preventing re and explosion hazards
• Working with the Charge Controller may produce arcs or sparks. Thus, the Charge
Controller should not be used in areas where there are inammable materials or gases
requiring ignition protected equip ment. These areas may include spaces containing
gasoline powered machinery, fuel tanks, battery compartments.
Precautions when working with batteries
• Batteries contain very corrosive, diluted sulphuric acid as electrolyte. Precautions should
be taken to prevent contact with skin, eyes or clothing.
• Batteries generate hydrogen and oxygen during charging, resulting in evolution of
explosive gas mixture. Care should be taken to ventilate the battery area and follow the
battery manufacturer’s recommendations.
• Never smoke or allow a spark or ame near the batteries.
