The Power Train Electric Drive 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 or the power train components while the engine is operating. Do not perform any type of electrical maintenance on the orange hazardous voltage conductors or the power train 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. Failure to follow these instructions could result in personal injury or death.

1. Perform the electrical shutdown and voltage discharge procedure. Refer to Operation and Maintenance Manual, "Electrical Shutdown and Voltage Discharge" for the correct procedure.
