Follow These Steps When Battery Is Outside Vehicle; Grounding And Ac Power Cord Connections - Schumacher Electric SC1278 Owner's Manual

7. 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:
7.1 Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has a
larger diameter than NEGATIVE (NEG, N, –) post.
7.2 Attach at least a 24-inch-long 6-gauge (AWG) insulated battery cable to
NEGATIVE (NEG, N, –) battery post.
7.3 Connect POSITIVE (RED) charger clip to POSITIVE (POS, P, +) post of battery.
7.4 Position yourself and free end of cable as far away from battery as possible – then
connect NEGATIVE (BLACK) charger clip to free end of cable.
7.5 Do not face battery when making final connection.
7.6 When disconnecting charger, always do so in reverse sequence of connecting
procedure and break first connection while as far away from battery as practical.
7.7 A marine (boat) battery must be removed and charged on shore. To charge it on
board requires equipment specially designed for marine use.

8. GROUNDING AND AC POWER CORD CONNECTIONS

8.1 This battery charger is for use on a nominal 120 volt circuit. The unit 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.
8.2 DANGER: Never alter the AC cord or plug provided – if it does not fit the outlet,
have a proper grounded 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.
8.3 USING AN EXTENSION CORD
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:
