SC Series User Manual

short-circuit battery or other electrical part that may cause explosion.

 Remove personal metal items such as rings, bracelets, necklaces, and watches when

working with a lead-acid battery. A lead-acid battery can produce a short-circuit current

high enough to weld a ring or the like to metal, causing a severe burn.

 NEVER charge a frozen battery.

 If necessary to remove battery from vessel, always remove grounded terminal from

battery first. Make sure all accessories in the vessels are off, so as not to cause an arc.

 Be sure area around battery is well ventilated.

 Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.

 Study all battery manufacturer’s specific precautions such as removing or not removing

cell caps while charging and recommended rates of charge

 Add distilled water in each cell until battery acid reaches level specified by battery

manufacturer. This helps purge excessive gas from cells. Do not overfill. For a battery

without cell caps, carefully follow manufacturer’s recharging instructions.

8. MARINE UNIT LOCATION

 Locate marine unit away from battery in a separate, well ventilated compartment.

 Never place marine unit directly above battery; gases from battery will corrode and

damage marine unit.

 Do not operate marine unit in a closed-in area or restrict ventilation in any way.

9. DC CONNECTION PRECAUTIONS
