Associated Equipment BC-91305 Charger Location, DC Connection Precautions

15.CHARGER LOCATION

a.Locate the charger as far away from the battery as the DC cables permit.

b.Never place the charger directly above the battery being charged; gases from the battery will corrode and damage the charger.

c.Never allow battery acid to drip on the charger when reading the specific gravity or filling battery,

d.Do not operate the charger in a closed-in area, or restrict ventilation in any way.

e.Do not set a battery on top of the charger.

16.DC CONNECTION PRECAUTIONS

a.Connect and disconnect the DC output clamps only after removing the AC cord from the electric outlet. Never allow the clamps to touch each other.

b.Attach the DC clamps to the battery post and twist or rock back and forth several times to make a good connection. This tends to keep the clamps from slipping off the terminals and helps to reduce the risk of sparking.

17.FOLLOW THESE STEPS WHEN THE BATTERY IS INSTALLED IN A VEHICLE. A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY:

a.Position the AC and DC cords to reduce the risk of damage by the hood, door, or moving engine parts.

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

c.Check the polarity of the battery post. The POSITIVE (POS, P, +) battery post usually has a larger diameter than the NEGATIVE (NEG, N, -) post.

d.Determine which post of the battery is grounded (connected) to the chassis. If the negative post is grounded to the chassis (as in most vehicles), see item "e". If the positive post is grounded to the chassis, see item "f".

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

f.For positive-grounded vehicles, connect the NEGATIVE (BLACK) clamp from the battery charger to the NEGATIVE (NEG, N, -) ungrounded post of the battery. Connect the POSITIVE (RED) clamp to the vehicle chassis or engine away from the battery. Do not connect the clamp to the carburetor, fuel lines, or sheet-metal body parts. Connect to a heavy gauge metal part of the frame or engine block.

g.When disconnecting the charger, disconnect the AC cord, remove the clamp from the vehicle chassis, and then remove the clamp from the battery terminal.

h.See the operating instructions for length of charge information.

18.FOLLOW THESE STEPS WHEN THE BATTERY IS OUTSIDE THE VEHICLE. A SPARK NEAR THE BATTERY MAY CAUSE BATTERY EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY:

a.Check the polarity of the battery post. The POSITIVE (POS, P, +) usually has a larger diameter than the NEGATIVE (NEG, N, -) post.

b.Attach at least a 24 inch long 6-gauge (AWG) insulated battery cable to the NEGATIVE (NEG, N, -) battery post.

c.Connect the POSITIVE (RED) charger clamp to the POSITIVE (POS, P, +) post of the battery.

d.Position yourself and the free end of the cable as far away from the battery as possible, then connect the NEGATIVE (BLACK) charger clamp to the free end of cable.

e.Do not face the battery when making the final connection.

f.When disconnecting the charger, always do so in reverse sequence of connecting procedure, and break the first connection while standing as far away from the battery as practical.

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

19.VEHICLES WITH TWO BATTERIES

Many diesel vehicles and service vehicles are equipped with two batteries. This is to provide the vehicle with greater starting power capacity or longer reserve capacity to provide power for accessories. These batteries are wired into a parallel circuit. Because of this, it will take twice as long to charge these batteries. See section 21 CHARGE PERIOD.

If one battery is charged and the other discharged, the discharged battery should be removed from the vehicle and checked. When attaching the charger to this type of vehicle the charger should be attached to the battery which is wired closest to the starter. This allows the charger to provide maximum starting power to the starter motor by minimizing the voltage drop in the engine cables.

20.GROUNDING AND AC POWER CORD CONNECTION INSTRUCTIONS

The charger should be grounded to reduce the risk of electric shock. This 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 all local codes and ordinances.

DANGER. Never alter the AC cord or plug provided - if it will not fit the outlet, have a proper outlet installed by a qualified electrician. Improper connection can result in a risk of an 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 FIGURE (A). A temporary adapter, which looks like the adapter illustrated in FIGURE (C), may be used to connect this plug to a two-pole receptacle, as shown in FIGURE (B), until a properly grounded outlet can be installed by a qualified electrician.
