DC CONNECTION PRECAUTIONS

5.1 Connect and disconnect the DC output ring terminals only after
removing the AC plug from electric outlet.
5.2 Attach the ring terminals to the battery and chassis, as indicated
in sections 6 and 7.
6. FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN
VEHICLE
6.1 Position the AC and DC cables to reduce the risk of damage by
the hood, door 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 ring terminals
or cut the insulation of the cables.
6.2
Stay clear of fan blades, belts, pulleys and other parts that can
cause injury.
6.3 Check the polarity of the battery posts. The POSITIVE (POS, P,
+) battery post usually has a larger diameter then the NEGATIVE
(NEG, N, -) post.
6.4 Determine which post of the battery is grounded (connected) to
the chassis. 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.
