OWN RISK.
1.2 Precautions When Working with Batteries
1.2.1 If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eye,
immediately flood eye with running cold water for at least 20 minutes and seek medical attention
immediately.
1.2.2 Never smoke or allow an open spark or flame in the vicinity of battery or engine. When batteries are
being recharged, they generate hydrogen gas that is explosive in certain concentrations in air (explosive
limits are 4.1 to 72 percent hydrogen in air). The ventilation system can exchange an adequate amount of
fresh air for the number of batteries being charged. This is essential to prevent an explosion.
1.2.3 Do not allow metal objects to contact the battery terminals. The resulting spark or short-circuit on the
battery of other electrical part may cause an explosion.
1.2.4. Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a
lead-acid battery. A lead-acid battery produces a short-circuit current high enough to weld a ring or the like
to metal, causing a severe burn.
1.2.5 To reduce the risk of injury, charge only rechargeable batteries suitable for use by this inverter such as
deep-cycle lead acid, lead antimony, lead calcium gel cell, absorbed mat, NiCad/NiFe or Lithium battery.
Other types of batteries may burst, causing personal injury and damage. NEVER charge a frozen battery.
See battery type of this manual for more information about acceptable battery types and program settings.
1.2.6 Don’t install the inverter near batteries, the inverter may heat battery electrolyte and cause corrosive
fumes to vent and damage/corrode nearby electronics or metals.
