FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE

WARNING: A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY EXPLOSION.
TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY:
Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has a larger diameter than
7.1
NEGATIVE (NEG, N, –) post.
Attach at least a 24-inch-long 6-gauge (AWG) insulated battery cable to NEGATIVE (NEG, N, –) battery post.
7.2
Connect POSITIVE (RED) charger clip to POSITIVE (POS, P, +) post of battery.
7.3
Position yourself and free end of cable as far away from battery as possible – then connect NEGATIVE
7.4
(BLACK) charger clip to free end of cable.
Do not face battery when making final connection.
7.5
When disconnecting charger, always do so in reverse sequence of connecting procedure and break first
7.6
connection while as far away from battery as practical.
A marine (boat) battery must be removed and charged on shore. To charge it on board requires
7.7
equipment specially designed for marine use.

GROUNDING AND AC POWER CORD CONNECTIONS

This battery charger is for use on a nominal 120 volt circuit and has a grounded plug. The charger must
8.1
be grounded, to reduce the risk of electric shock. The plug must be plugged into an outlet that is properly
installed and grounded in accordance with all local codes and ordinances. The plug pins must fit the
receptacle (outlet). Do not use with an ungrounded system.
DANGER: Never alter the AC cord or plug provided – if it does not fit the outlet, have a proper grounded
8.2
outlet installed by a qualified electrician. An improper connection can result in a risk of an electric shock
or electrocution.
NOTE: Pursuant to Canadian Regulations, use of an adapter plug is not allowed in Canada. Use of an
adapter plug in the United States is not recommended and should not be used.

USING AN EXTENSION CORD

8.3
The use of an extension cord is not recommended. If you must use an extension cord, follow these guidelines:
• Pins on plug of extension cord must be the same number, size, and shape as those of plug on charger.
• Ensure that the extension cord is properly wired and in good electrical condition.
• Wire size must be large enough for the AC ampere rating of charger, as specified:

*If the input rating of a charger is given in watts, rather than in amperes, the corresponding ampere rating is
determined by dividing the wattage rating by the voltage rating, for example: 1200 watts/120 volts=10 amperes.
