03. DISABLE DIRECT HAZARDS SAFETY REGULATION
14
Automatic disconnection
If a serious accident occurs the Supplemental
Restraint System (SRS) sets the vehicle to
Crash mode and the traction battery pack is
automatically disconnected from the rest of the
high voltage system
Make sure the traction battery is disconnected
before starting any rescue procedures. Please see
the section “High voltage Manual service discon-
nect” in this chapter.
WARNING
Residual voltage can remain in the system
outside the traction battery for approximately
10 seconds after the accident.
Make sure that the vehicle is
stabilized and turned off
When possible, always make sure that
the vehicle is turned off and stabilized.
See chapter 02. IMMOBILISATION/
STABILISATIONLIFTING for more
information.
WARNING
• Shutting off power to an electrical vehicle
does not de-energize the battery and a
shock hazard may still be present.
• Unless absolutely necessary, do not touch
any of the high voltage harnesses and/or
components. Touching high voltage com-
ponents, wires or harnesses might result in
personal injury or death.
• If the situation requires operations on any
of the high voltage components and/or
harnesses, always wear the appropriate
Personal Protective Equipment (PPE) to
avoid electrical shock. Failure to do so can
result in serious injury or death.
• NEVER assume that the electrical vehicle
is turned OFF because it is silent. The
electrical motor is silent and may still
be running. When possible, always take
appropriate actions to turn the vehicle
completely off and disconnect the high
voltage system before performing rescue
operations.
• Regardless of which procedure is used to
disable the high voltage system, always
assume that high voltage components are
energized. Take proper actions to avoid
unnecessary risks.
