a. Connect and disconnect DC output clamps only after setting charger switches on OFF position and removing AC cord from electric outlet. Never allow clamps to touch each other.
b. Attach clamps to battery post and twist or rock back and forth several times to make a good connection. This tends to keep clamps from slipping off terminals and helps to reduce risk of sparking.
7. FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE. A SPARK NEAR THE BATTERY MAY
CAUSE BATTERY EXPLOSION. TO REDUCE RISK OF A SPARK NEAR BATTERY:
a. Position AC and DC cords to reduce risk or damage by hood, door, or moving engine parts.
b. Stay clear of fan blades, belts, pullets, and other parts that can cause injury to persons.
c. Check polarity of battery post. POSITIVE (POS, P, +) battery post usually has a larger diameter than NEGATIVE (NEG, N, -) post.
d. Determine which post of battery is grounded (connected) to the chassis. If negative post is grounded to the chassis (as in most vehicles), see item "e." If positive post is grounded to the chassis, see item f.
e. For negative-grounded vehicle, connect POSITIVE (RED) clamp from the battery charger to POSITIVE (POS, P, +) ungrounded post of battery. Connect NEGATIVE (BLACK) clamp to vehicle chassis, heavy
gauge metal part of frame, or engine block away from battery. Do not connect the clamp to carburetor, fuel lines, or sheet metal part of the frame.
f. For positive-grounded vehicle, connect NEGATIVE (BLACK) clamp from battery charger to NEGATIVE (NEG, N, -) ungrounded post of battery. Connect POSITIVE (RED) clamp to vehicle chassis or engine
block away from battery. Do not connect clamp to 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, turn switches to off, disconnect AC cord, remove clamp from vehicle chassis, and then remove clamp from battery terminal.
h. See operating instructions for length of charge information.
8. FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE. A SPARK NEAR THE BATTERY MAY CAUSE
BATTERY EXPLOSION. TO REDUCE RISK OF A SPARK NEAR BATTERY:
a. Check polarity of battery post. POSITIVE (POS, P, +) battery post 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 POSITIVE (RED) charger clamp to POSITIVE (POS, P, +) post of the battery.
d. Position yourself and free end of the cables as far away from the battery as possible, then connect the NEGATIVE (BLACK) charger clamp to free end of cable.
e. Do not face battery when making final connection.
f. When disconnecting the charger, always do so in reverse sequence of connecting procedure and break first connection while standing as far away from 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.
9. GROUNDING AND AC POWER CORD CONNECTION INSTRUCTIONS
This charger should be grounded to reduce 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 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 electric shock. This battery
charger is for use on a nominal 120 volt circuit. It has a grounding plug that looks like the plug illustrated in sketch (A). A temporary adapter, which looks like the adapter illustrated in sketch C, may be used to
connect this plug to a two-pole receptacle, as shown in sketch B, until a properly grounded outlet can be installed by a qualified electrician.
DANGER. Before using adapter as illustrated, be certain that center screw of outlet plate is grounded. The green-
colored rigid ear of 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 lug to
outlet cover plate and make ground connection to grounded outlet.
MOUNTING:
The Battery Charger may be set on a table or a shelf. Do not set charger on floor. It should be mounted such that the air
intake louvers are at least 18 inches from the floor. Regardless of how it is placed, the top and side louvers of the unit must
not be blocked. This is a convection cooled charger and blocking the louvers will damage the unit. When locating the unit,
take into account the number of batteries to be recharged and location of the recharging racks. Never place the charger such that battery acid or water may be spilled in the top of the unit. Never place the unit
directly over the batteries to be charged. Fumes caused by gassing batteries will be drawn through the charger by convection and cause damage to the unit.
CONTROLS:
AMMETER: Indicates the amount of current that the batteries are receiving. The larger the amount of current, the faster the batteries will charge. All batteries in a series group will receive the same amount of
current. Do not exceed 6 amps charge rate.
MAIN POWER SWITCH: This switch turns the power off to the entire charging unit. Any time the charger is not being used, this switch should be turned off to conserve energy.
RANGE SWITCH: The range switch should be set in the LOW position when charging 24 cells or less in order to obtain a stable current adjustment.
CURRENT LIMIT ADJUST: After attaching the clamps to the batteries, charging current can be set by turning the knob clockwise to increase and counter-clockwise to decrease. Do not exceed 6 amps. There
will be a slight 2 - 3 second delay after attaching the clamps before current can be set.
NOTE: The charger will not begin charging if the battery voltage is below 3 Volts. If this condition exists, connect a good battery in parallel, observing proper polarity, for a few seconds until charging
begins. Adjust charging current and then remove the parallel battery. Turn Current Limit Adjust full counter-clockwise before removing the clamps.
SAFETY FEATURES:
REVERSE POLARITY PROTECTION: If the DC clamps are hooked up incorrectly to the battery, the control will not turn on to allow output voltage.
ANTI-SPARKING PROTECTION: If the DC clamps are connected in proper polarity to a battery of 3 or more volts, 2 to 3 seconds of delay occurs before output voltage turns on. If one of the clamps is
momentarily disconnected, output voltage shuts off immediately and requires another 2 to 3 seconds to turn on again.
CAUTION ! ! !
When a number of batteries are connected in series, a high DC voltage exists at the terminals of the end batteries. When not connected, the charger DC leads will have no output voltage but the battery terminal
may still present a shock hazard.
SERIES CHARGING:
Connecting batteries in series (see illustration D) allows a person to charge a number of batteries at one time using only one low current, high voltage charger. The amount of charge that each battery receives
