WARNING:
To prevent the risk of high-voltage shock, always follow
precisely all warnings and service instructions, including instructions
to depower the system. The high-voltage system utilizes approximately
300 volts DC, provided through high-voltage cables to its components and
modules. The high-voltage cables and wiring are identified by orange
harness tape or orange wire covering. All high-voltage components are
marked with high-voltage warning labels with a high-voltage symbol.
Failure to follow these instructions may result in serious personal
injury or death.

WARNING:
To prevent the risk of high-voltage shock, always follow
precisely all warnings and service instructions, including instructions
to depower the system. The high-voltage system utilizes approximately
300 volts DC, provided through high-voltage cables to its components and
modules. The high-voltage cables and wiring are identified by orange
harness tape or orange wire covering. All high-voltage components are
marked with high-voltage warning labels with a high-voltage symbol.
Failure to follow these instructions may result in serious personal
injury or death.
