WARNING – RISK OF EXPLOSIVE GASES) WORKING IN VICINITY OF A LEAD-ACID BATTERY IS

DANGEROUS. BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL BATTERY OPERATION.

FOR THIS REASON, IT IS OF UTMOST IMPORTANCE THAT EACH TIME BEFORE SERVICING THE UNIT

IN THE VICINITY OF THEBATTERY, YOU READ THIS MANUAL AND FOLLOW THE INSTRUCTIONS

EXACTLY.

PERSONAL PRECAUTIONS

• Someone should be within range of your voice or close enough to come to your aid when you work near a

lead-acid battery

• Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.

• Wear complete eye protection and clothing protection. Avoid touching eyes while working near battery.

• 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 10 min and get medical attention immediately.

• NEVER smoke or allow a spark or flame in vicinity of battery or engine.

• Be extra cautious to reduce risk of dropping a metal tool onto battery. It might spark or 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.

• 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.

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.

• Never allow battery acid to drip on marine unit when reading gravity or filling battery.

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

DC CONNECTION PRECAUTIONS

Connect and disconnect DC output connections only after setting any marine unit switches to off position and

removing AC cord from electric outlet or opening AC disconnect.

EXTERNAL CONNECTIONS TO CHARGER SHALL COMPLY WITH THE UNITED STATES COAST GUARD

ELECTRICAL REGULATIONS (33CFR183, SUB PART I).

GROUNDING INSTRUCTIONS – This marine unit should be connected to a grounded, metal, permanent
