SAFETY INSTRUCTIONS
Please read these instructions before installing or operating the Charge Controller to prevent personal
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 certified 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 qualified 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 dangerousVoltages.
• Be careful when touching bare terminals of capacitors. The capacitors may retain high
lethalVoltages 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 fire 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 inflammable 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 flame near the batteries.
• Use caution to reduce the risk of dropping a metal tool on the battery. It could spark or short
circuit the battery or other electrical parts and could cause an explosion.
• Remove metal items like rings, bracelets and watches when working with batteries. The
