Caution: DC and AC high-voltage is present. To reduce the risk of severe shocks and burns, the high-voltage system should be disabled any time service work is being performed on or around the high-voltage system. When in doubt, always disable the high-voltage system. The 12-volt system will still be active after the high-voltage system has been disabled.
The S-10 Electric Truck has both high-voltage DC and AC systems, as well as a 12-volt system. DC and AC high-voltage are both very dangerous and can cause severe burns and shock. You first need training about how to repair the S-10 Electric Truck and then must follow the proper repair procedures to minimize the task.
Currents as low as 0.5 mA AC or 2 mA DC can cause injuries under some conditions. The potential for injury depends on the current path through the body, the amount of current, and how long the current flows through the body. Other factors that influence the effect of current are the body's impedance, the frequency of the current, the moisture level of the skin, the size of the contact area, the pressure exerted, temperature, and the physiological characteristics of the individual.
AC and DC high-voltage affect the body differently. The varying current with AC high-voltage is more traumatic to the body and can also prevent letting go of the electrode.
The high-voltage system is independent and isolated from the 12-volt system. When a failure is detected, the high-voltage system is automatically disconnected. There is also a manual disconnect that must be used before service work is performed on or around the high-voltage system.
To help avoid injury:
| • | Do not work on the S-10 Electric Truck without training. Even the greatest gasoline engine technician needs training for this truck. |
| • | Follow the service manual procedures and cautions. |
| • | ALWAYS assume that high-voltage is present. |
| • | To prevent current from having a path through your body, use one hand to do an operation on the high-voltage system. |
| • | Use electrical tape to cover all metal parts of your tools to reduce the chance that the tools will complete a current path. |
The battery pack has at least 26 times the energy of one regular automotive battery. Extra precautions are required when the battery pack is removed from the vehicle because the automatic and manual disconnect cannot protect you from a disconnected battery pack. Follow the service manual procedures and cautions.
