Assembly Instructions; Grounding And Ac Power Cord Connections; Features - Schumacher XC75 Owner's Manual

• Remove all cord wraps and uncoil the
cables prior to using the battery charger.
• Included with your charger are two cord
wrap cleats for storage of the clamp cables.

GROUNDING AND AC POWER CORD CONNECTIONS

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.
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.
DIGITAL DISPLAY
The Digital Display gives a digital indication
of voltage or % of charge. 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 the
charger determined the battery is). If you
manually stop the charging process (by
pressing the RATE SELECTION button)
before the battery is fully charged, the
display will show OFF.
• Battery % – The digital display shows an
estimated charge percentage of the battery
connected to the charger's battery clamps.
• Voltage – The Digital Display shows the
voltage at the charger battery clamps, in
DC volts.
RATE SELECTION
Press this button until the desired charge
rate is selected.
• 3A MAINTAIN – Used to keep stored
lead-acid batteries charged. Charges and
maintains small batteries. Maintains large
batteries that are already fully charged.
• 5A CHARGE – For charging small batteries,
such as those commonly used in garden
tractors, snowmobiles and motorcycles.
Also used to completely charge deep-cycle
batteries.
