4.4.10 Installing Battery Cables
Prerequisites
D ANGER
● Smoking and sources of ignition are prohibited near batteries.
● Flip the battery switch to OFF before installing batteries.
● Comply with regulations and warnings issued by the battery manufacturer.
● Use tools with insulated handles. Using tools without insulated handles may
cause personal injury or result in batteries burning out.
● Before handling batteries, wear goggles, rubber gloves, and protective clothes.
Remove any conductors such as jewelry or watches.
● Ensure that battery acid does not come into contact with the eyes. If battery
acid gets in the eyes, rinse the eyes with cold water for at least 15 minutes and
then seek medical advice immediately. If battery acid comes into contact with
skin or clothing, immediately wash the affected area with soap and water.
● Do not use metal or conductors to simultaneously touch two or more battery
terminals. Do not use metal or conductors to simultaneously touch battery
terminals and grounded objects (for example, the battery compartment);
otherwise, transient short circuits will occur, which may produce sparks or
explosions.
● During battery installation, ensure that the positive and negative battery
terminals are correctly connected to prevent reverse polarity. First connect the
negative battery cable and then connect the positive battery cable.
● Secure battery cables to the torque specified in battery documentation. Loose
connections will result in excessive voltage drops or cause batteries to burn out
when the current increases.
