B. PERSONAL PRECAUTIONS AND SAFETY

1. WARNING: Wear complete eye protection and clothing

protection, when working with lead-acid batteries.

2. Make sure someone is within range of your voice or close enough to come to your aid when you work with or near a lead-acid battery.

3. Have plenty of fresh water and soap nearby for use if battery acid contacts skin, clothing, or eyes. If battery acid contacts skin or clothing, wash immediately with soap and water.

4. Avoid touching your eyes while working with a battery. Acid particles (corrosion) may get into your eyes! If acid enters your eye, immediately flood eye with running cold water for at least 10 minutes. Get medical attention immediately.

5. Remove all 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.

6. Take care not to drop a metal tool or other metal onto the battery. Metal may cause sparking or short circuit the battery or another electrical devise. Sparking may cause an explosion.

7. Always operate battery charger in an open well ventilated area.

8. NEVER smoke or allow a spark or flame in the vicinity of the battery or engine. Batteries generate explosive gases!

C. PREPARING TO CHARGE

1. Make sure you have a 12 or 24 volt lead-acid battery. Check car owner manual to make sure.

2. Clean battery terminals. Take care to keep corrosion from coming in contact with your eyes.

3. If required, add distilled water in each cell until battery acid reaches levels 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.

4. Study all battery manufacturer's specific precautions, such as removing or not removing cell caps while charging, and recommended rates of charge.

5. Be sure area around battery is well ventilated while battery is being charged. Gas can be forcefully blown away by using a piece of cardboard or other non-metallic material as a fan.

6. If necessary to remove battery from vehicle to charge, always remove grounded terminal from battery first. Make sure all accessories in the vehicle are off, so as not to cause an arc.

7. A marine (boat) battery must be removed and charged on shore. To charge it on board requires equipment specially designed for marine use.

GROUNDING AND AC POWER CORD CONNECTION INSTRUCTIONS - Charger should be grounded to reduce risk of electric

shock. Charger is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into an outlet that is properly installed and grounded in accordance with local codes and ordinances.

DANGER - Never alter AC cord or plug provided - if it will not fit outlet, have proper outlet installed by a qualified electrician. Improper connection can result in a risk of electric shock.

This battery charger is for use on a nominal 120-volt circuit, and has a grounding plug that looks like the plug illustrated in sketch A. A temporary adapter, which looks like the adapter illustrated in sketch B, may be used to connect this plug to a two-pole receptacle as shown in sketch B if a properly grounded outlet is not available. The temporary adapter should be used only until a properly grounded outlet can be installed by a qualified electrician.

When charging a battery in a RV or motor home always connect one lead of the output cable to the battery. Never connect to a remote receptacle or other means for the purpose of remotely charging the battery. The wires may be inadequate for handling the charge current of this charger and may over heat. Often these wires are bundled in with other wires which could be damaged and lead to a direct short across the battery and charger. If this occurs a fire can result, equipment and appliances operated from the battery may also be damaged.

GROUNDED OUTLET

GROUNDING PIN

DANGER - Before using adapter as illustrated, be certain that center screw of outlet plate is grounded. The green-colored rigid ear or lug extending from adapter must be connected to a properly grounded outlet - make certain it is grounded. If necessary, replace original outlet cover plate screw with a longer screw that will secure adapter ear or lug to outlet cover plate and make ground connection to grounded outlet.

Use of an adapter plug is not allowed in Canada.

E. DC CONNECTION PRECAUTIONS

1. Connect and disconnect DC output clamps only after setting any charger switches to off position and removing AC cord from electric outlet. Never allow clamps to touch each other.

2. Attach clamps to battery posts and twist or rock back and forth several times to make a good connections This tends to keep clamps from slipping off terminals and helps to reduce risk of sparking.

F. FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE

A SPARK NEAR BATTERY MAY CAUSE BATTERY EXPLOSION. FOLLOW THESE STEPS TO REDUCE RISK OF SPARK NEAR BATTERY:

1. Position AC and DC cords to reduce risk of damage by hood, door, or moving engine part.

2. Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.

3. Check polarity of battery posts. POSITIVE (POS, P,+) battery post usually has larger diameter than NEGATIVE (NEG, N, ) post.

4. Determine which post of battery is grounded (connected to the chassis). If negative post is grounded to chassis (as in most vehicles), see No. 5. If positive post is grounded to the chassis, see No. 6.

5. For a negative-grounded vehicle, connect POSITIVE (RED) clamp from battery charger to POSITIVE (POS, P,+) ungrounded post of battery. Connect NEGATIVE (BLACK) clamp to vehicle chassis or engine block away from battery. Do not connect clamp to carburetor, fuel lines, or sheetmetal body parts. Connect to a heavy gage metal part of the frame or engine block. (Figure 2)

I. OPERATION INSTRUCTIONS

1. These battery chargers are equipped with a self-resetting circuit breaker. This device protects the charger from temporary overloads. In the event of an overload, the circuit breaker will trip open, and after a short cooling off period, will reset automatically. This process is known as cycling and can be recognized by an audible clicking sound.

2. These battery chargers are equipped with an electronic control circuit which automatically governs the charge rate to your battery. The charger will satisfactorily charge Maintenance Free and Conventional batteries.

J. OUTPUT VOLTAGE

This charger is for use with 12 volt lead-acid batteries. The SE-70MA is for 12 and 24 volt systems.

K. INDICATION OF PROPER OPERATION TO A DISCHARGED BATTERY

BUT OTHERWIDE IN GOOD CONDITION

10 Amp 12 Volt setting: The initial charge current should be 10 amps gradually tapering throughout the charge cycle to 5 amps. Though not indicated, battery voltage will gradually rise to approximately 14.3 volts, then hold constant throughout remainder of charge cycle. When the battery reaches 14.3 volts and charge current drops to 5 amps the charger will turn off. Initially the battery voltage will drop from its 14.3 volt level fairly quickly. When 13 volts is reached, the charger will again turn on, until the 14.3 volt, 5 amp condition is met. As this action continues, on time will decrease to a few seconds while off time increases to a range of several minutes to an hour. on/off times vary with size, type and condition of battery.
