Follow These Steps When Battery Is Outside Vehicle; Grounding And Ac Power Cord Connections; Control Panel - Schumacher SC1393 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

8. GROUNDING AND AC POWER CORD CONNECTIONS

8.1 This battery charger is for use on a
nominal 120 volt circuit. 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.
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.
9. ASSEMBLY INSTRUCTIONS
9.1 Remove all cord wraps and uncoil the cables prior to using the battery charger.

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.
8.3 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:
Length of cord (feet)
AWG* size of cord
*AWG-American Wire Gauge
DIGITAL DISPLAY
The display will show the battery VOLTAGE
when the charger is not charging a battery.
When it goes into charging mode, the
display will automatically change to ON (to
show charging has started) and then show
the percent-of-charge of the battery being
charged and either 6 or 12 (the voltage of
the battery, determined by the charger). If
you manually stop the charging process
(by pressing the
before the battery is fully charged, the
display will show OFF.
