Prevent Electrical Shock and Fires

PC12631-UN-04JUN10

Battery-powered equipment or other electric power sources produce an electrical shock, sparks, or arcs if a short circuit occurs. Electrical short circuits can reach temperatures high enough to burn people, or ignite or melt common materials.

To prevent injury from electrical shock, burns, or potential fire hazards, always disconnect battery power or other electric power source on equipment before installing or servicing:

• Remove ground (negative terminal [-]) battery clamp.
• Detach and remove battery.
• Switch off main battery or other electric power source.
• Unplug electric power source from equipment.

Understand and follow all local codes and regulations when installing electrical equipment.
