Schumacher SEM-1562A owner manual DC Connection Precautions

4.3Do not set the battery on top of the charger.

4.4Never allow battery acid to drip onto the charger when reading the electrolyte specific gravity or filling the battery.

4.5Do not operate the charger in a closed-in area or restrict the ventilation in any way.

5.DC CONNECTION PRECAUTIONS

5.1Connect and disconnect the DC output clips only after setting all of the charger switches to the “off” position (if applicable) and removing the AC plug from the electrical outlet. Never allow the clips to touch each other.

5.2Attach the clips to the battery and chassis, as indicated in sections 6 and 7.

6.FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE

A SPARK NEAR THE BATTERY MAY

CAUSE A BATTERY EXPLOSION.

TO REDUCE THE RISK OF A SPARK

NEAR THE BATTERY:

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 battery clips or cut the insulation of the cables.

6.2Stay clear of fan blades, belts, pulleys and other parts that can cause injury.

6.3Check the polarity of the battery posts. The POSITIVE (POS, P, +) battery post usually has a larger diameter then the NEGATIVE (NEG, N, -) post.

6.4Determine 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.

6.5For a negative-grounded vehicle, connect the POSITIVE (RED) clip from the 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
