DC CONNECTION PRECAUTIONS
5.
Connect and disconnect the DC output clips only after removing the AC plug
5.1
from the electrical outlet. Never allow the clips to touch each other.
Attach the clips to the battery and chassis, as indicated in sections 6 and 7.
5.2
FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN
6.
VEHICLE.
A spark near the battery may cause a
battery explosion. To reduce the risk
of a spark near the battery:
Position the AC and DC cables to reduce the risk of damage by the hood, door
6.1
and moving or hot engine parts. NOTE: If it is necessary to close the hood
during the charging process, ensure that the hood does not touch the metal
part of the battery clips or cut the insulation of the cables.
Stay clear of fan blades, belts, pulleys and other parts that can cause injury.
6.2
Check the polarity of the battery posts. The POSITIVE (POS, P, +) battery
6.3
post usually has a larger diameter then the NEGATIVE (NEG, N, -) post.
Determine which post of the battery is grounded (connected) to the chassis.
6.4
If the negative post is grounded to the chassis (as in most vehicles), see step
6.5. If the positive post is grounded to the chassis, see step 6.6.
For a negative-grounded vehicle, connect the POSITIVE (RED) clip from the
6.5
battery charger to the POSITIVE (POS, P, +) ungrounded post of the battery.
Connect the NEGATIVE (BLACK) clip to the vehicle chassis or engine block
away from the battery. Do not connect the clip to the carburetor, fuel lines or
sheet-metal body parts. Connect to a heavy gauge metal part of the frame or
engine block.
For a positive-grounded vehicle, connect the NEGATIVE (BLACK) clip from
6.6
the battery charger to the NEGATIVE (NEG, N, -) ungrounded post of the
battery. Connect the POSITIVE (RED) clip to the vehicle chassis or engine
block away from the battery. Do not connect the clip to the carburetor, fuel
lines or sheet-metal body parts. Connect to a heavy gauge metal part of the
frame or engine block.
Connect the AC supply cord to the electrical outlet.
6.7
When disconnecting the charger, disconnect the AC cord, remove the clip
6.8
from the vehicle chassis and then remove the clip from the battery terminal.
See CALCULATING CHARGE TIME for length of charge information.
