DC CONNECTION PRECAUTIONS
a) Connect and disconnect dc output Battery Clamps only after setting any charger
switches to “off” position and removing ac cord from electric outlet. Never allow Battery
Clamps to touch each other.
b) Attach Battery Clamps to battery and chassis as indicated.
FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE.
A SPARK NEAR BATTERY MAY CAUSE BATTERY EXPLOSION. TO
REDUCE RISK OF A SPARK NEAR BATTERY:
a) Position ac and dc cords to reduce risk of damage by hood, door, or moving engine part.
b) Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.
c) Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has 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 chassis (as in most vehicles), see (e). If positive post is grounded to the
chassis, see (f).
e) For negative-grounded vehicle, connect POSITIVE (RED) Battery Clamp from battery
charger to POSITIVE (POS, P, +) ungrounded post of battery. Connect NEGATIVE (BLACK)
Battery Clamp to vehicle chassis or engine block away from battery. Do not connect
Battery Clamp to carburetor, fuel lines, or sheet-metal body parts. Connect to a heavy
