MultiPlus-II 2x120V WARNING – RISK OF EXPLOSIVE GASES. WORKING IN THE VICINITY OF A LEAD-ACID BATTERY IS HAZARDOUS. LEAD-ACID BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL OPERATION. Please observe the following precautions when working in the vicinity of a lead-acid battery. PERSONAL SAFETY PRECAUTIONS: Never work alone near a lead-acid battery. Ensure someone is close-by to assist you in case of an emergency. Ensure first aid and eye wash equipment is readily available before working on or near the battery. Wear safety goggles or a face shield and protective clothing. Avoid touching your eyes while working near a battery.
If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters your eye, immediately flush the eye with cold running water for at least 10 minutes and seek medical attention right away. NEVER smoke or allow sparks or open flames within the vicinity of a battery or engine. Use insulated tools when working on the battery. Be extremely careful not to drop metal tools or objects onto the battery. A dropped metal tool can create sparks or cause a short circuit, which may result in an explosion or fire. Remove metal jewelry and watches when working with a lead-acid battery.
A lead-acid battery can produce a short-circuit current high enough to melt or weld a ring or similar metal object to metal, causing severe burns. NEVER charge a frozen battery. If removing the battery from a vehicle or vessel, always remove grounded terminal from the battery first. Switch off all circuits before connecting or disconnecting the battery terminals to prevent arcing. Ensure the battery is installed in a well ventilated space. Keep the battery terminals clean and free of corrosion. Prevent corrosion material from coming in contact with eyes. Always follow the battery manufacturer’s specific precautions and instructions.
This includes whether or not to remove the cell caps while charging and observe the recommended charging rates. MARINE UNIT LOCATION Locate marine unit away from battery in a separate, well ventilated compartment Never place marine unit directly above the battery; corrosive battery gases will damage it. Never allow battery acid to drip onto the marine unit when reading gravity or filling the battery. Do not operate the 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. Disconnect AC cords from electric outlets or open AC disconnect switches.
EXTERNAL CONNECTIONS SHALL COMPLY WITH THE UNITED STATES COAST GUARD ELECTRICAL REGULATIONS (33CFR183, SUB PART I). GROUNDING INSTRUCTIONS – A marine unit should be connected to a grounded, metal, permanent wiring system; or an equipment-grounding conductor should be run with circuit conductors and connected to equipment-grounding terminal or lead on unit. Connections to the unit should comply with all local codes and ordinances. This product is not suitable for direct connection to a vehicle's electrical system. It should be connected to a DC system that includes its own dedicated service or house battery with appropriate fusing, and DC wiring gauge.
For recommendations on battery capacity, fuse rating, and cable gauge, refer to Chapter Connection of battery cables [12] in this manual." Page 11 Installation
