Cautions
Page 3 of 12
Never touch the end of output cables with your bare hands when the modules are irradiated. Handle
wires with rubber-gloved hands to avoid electric shock.
Do not wear metallic jewelry when working on electrical equipment.
Product should be installed and maintained by qualified personnel.
Do not drop tool or other item on the glass of the solar module.
Do not scratch the back film of the solar panel.
Avoid exposing solar panels to partial sunlight or shadows. Partial sunlight can cause hot spots on
the panel.
Do not pour chemicals on module when cleaning.
Keep module away from children.
Precautions when working with batteries
Never smoke or allow a spark or flame near the batteries.
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.
Batteries contain very corrosive diluted sulphuric acid as electrolyte. Precautions should be taken to
prevent contact with skin, eyes or clothing.
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 batteries
can produce a short circuit current high enough to weld a ring or the like to metal and thus cause a
severe burn.
If you need to remove a battery, always remove the ground terminal from the battery first. make sure
that all the accessories are off so that you do not cause a spark.
Use properly insulated tools only when making battery connections.
Precautions when working with solar panels
With the incidence of sunlight or other light sources on all solar panels, a voltage appears at the
output terminals of the solar panel turning it into a source of electricity. To avoid a shock hazard
make sure the solar panel is covered with an opaque (dark) material such as paper/cloth during the
installation. Do not make contact with the terminals when the panel is exposed to sunlight or other
light sources.
Precautions when working with Charge Controllers
If two or more solar panels are connected in series/parallel make sure that the sum of the short
circuit current ratings of all panel strings does not exceed 80% of the charge controller’s current
rating.
