ii Prosine 2.5/3.0 Installation & Operation Guide12. WARNINGóRISK OF EXPLOSIVE GASESa) WORKING IN THE VICINITY OF A LEAD-ACID BATTERY IS DAN-GEROUS. BATTERIES GENERATE EXPLOSIVE GASES DURINGNORMAL BATTERY OPERATION. BEFORE INSTALLING ORUSING YOUR INVERTER/CHARGER, READ THIS MANUAL ANDFOLLOW THE INSTRUCTIONS EXACTLY.b) This equipment contains components which tend to produce arcs or sparks.To prevent fire or explosion do not install in compartments containing bat-teries or flammable materials or in locations which require ignition pro-tected equipment. This includes any space containing gasoline-poweredmachinery, fuel tanks, or joints, fittings, or other connection between com-ponents of the fuel system.c) To reduce the risk of battery explosion, follow these instructions and thosepublished by the battery manufacturer and the manufacturer of the equip-ment in which the battery is installed.13. PRECAUTIONS WHEN WORKING WITH BATTERIESa) Someone should be within range of your voice or close enough to come toyour aid when you work near a lead-acid battery.b) Have plenty of fresh water and soap nearby in case battery acid contactsskin, clothing, or eyes.c) Wear complete eye protection and clothing protection.
