SAFETY CRITICAL
1.0 PURPOSE
The purpose of this document is to instruct personnel how to lock off and isolate high voltage from the vehicle wiring and installed components.
High voltage will always remain inside the traction battery pack however isolating the battery pack will remove hazardous voltage from being
present on the DC bus and components connected to the DC bus, i.e., Siemens components, Hydrovane components and DC-DC converter.
2.0 SAFETY INFORMATION
2.1 The vehicle must be de-energized during all work on the inverter.
2.2 Danger!! Even after the vehicle has been powered down, hazardous voltages can still be present for a period of time.
2.3 The vehicle must be isolated from hazardous voltage.
2.4 The vehicle must be secured from switching on again.
2.5 The operator must wait at least 5 minutes for hazardous voltage on the DC capacitors to internally discharge.
2.6 The operator must verify that the equipment is not live.
