The Power Train Electric Drive System and the Accessory Power System will contain hazardous voltage levels during machine operation and for a period of time after machine shutdown. Do not remove any covers that will expose energized electrical components while the engine is operating. Do not remove any covers that will expose the energized electrical components while the components remain energized following an engine shutdown. Do not perform any type of electrical maintenance on the orange hazardous voltage conductors, the power train components or the accessory power system components while the engine is operating. Do not perform any type of electrical maintenance on the orange hazardous voltage conductors, the power train components or the accessory power system components while the components remain energized following an engine shutdown. Always perform the safe shutdown and de-energizing procedure before performing electrical service on the Power Train Electric Drive System or the Accessory Power System. Failure to follow these instructions could result in personal injury or death. |

The two top compartments on the front of the Inverter Cabinet contain low voltage control components. All of the other compartments in the cabinet contain high voltage components. The "Electrical Shutdown and Voltage Discharge" procedure must be performed before any of the high voltage compartments are entered. |
- Prepare the machine for maintenance. Refer to Operation and Maintenance Manual, "Prepare the Machine for Maintenance".
- Shutdown and de-energizing the machine. Refer to Operation and Maintenance Manual, "Electrical Shutdown and Voltage Discharge".
