1. SAFETY
During component removal or installation,
ensure that the vehicle is deengerized.
Set the Master Run switch to
the STOP-SYSTEM position and the
Batter Disconnect switch to the OFF
position. On vehicles equipped with a
High Voltage Interlock switch, ensure it
is in the High Voltage (HV) OFF position.
Lock and tag the switch and retain
the key. Failure to follow this procedure
may result in personal injury or component
damage.
1.1. High Voltage Safety
The Electric Drive System uses hazardous
High Voltage (HV) electrical energy.
There is a risk of electric shock. Only
trained service personnel should
access components of the High Voltage
Equipment. Failure to observe all HV
electrical safety precautions may result
in personal injury and/or death.
The highest concerns are for the safety
of service personnel working on the
vehicle and others in the vicinity, and in
minimizing the potential for damage to
property.
Death, serious injury, and significant
material damage will result if these
safety rules are not followed.

Fig. 1: PPE Categories
1.5.3. PPE Inspection
Inspect PPE equipment, before use, for
any degradation or damage and ensure
that the HV gloves have been tested every
6 months. Also perform an air pressure
test on the HV gloves before and after
each use. If, during PPE use, a potential
damaging incident occurred to the PPE,
stop further testing and inspect the PPE. If
at any time the PPE is defective, reject it,
and obtain an accepted one.
1.5.4. PPE Storage
PPE apparel should be stored lying flat,
undistorted, right-side out and not folded in
protective containers. The HV mats can be
rolled with an inside diameter greater than
2 inches. Rubber HV gloves should be
stored in cool, dark, dry, and free from
damaging chemicals or vapors. The glove
cuffs should face downwards, without folding,
in the appropriate glove bag and hung
vertically.
1.5.5. Electrical Injuries
Electrical injuries should be immediately
reported to first aid personnel and the
supervisor. Even non-injurious electrical
shocks, originating from components in the
HV system, should be reported to the
supervisor. All incidents should be immediately
investigated and documented to
determine the cause and prevent the
occurrence in the future.

1.6. Service Preparation
❒ The scope of the work must be accurately
defined such as a Servicing Procedure
that requires systematic steps with signoffs.
Before servicing is performed, the
Supervisor, Checker and Monitor/Recorder
must conduct a briefing of what shall transpire,
identify potential hazards and resist
pressures to speed through a procedure,
anticipate problems and question possible
events. If an unexpected electrical hazard
or fault occurs, during any service work, it
must be immediately reported to the
supervisor. After the work is completed the
same group should review the results and
processes and make proposed modifications
to the procedures if required.
❒ Install Safety barricade with warning lights
and signs indicating “Danger High Voltage”
around the vehicle perimeter and ensure
no personnel are within the fenced perimeter
during the service procedure.
❒ It shall always be the goal to check the
systems as much as possible with all HV
power OFF and Locked Out/Tagged Out
and proven as de-energized by voltage
measurement using a Category III or better
Digital Multimeter (DMM). The functionality
of the DMM must be proved before
and after the verification of no HV present.
Then, if possible, the HV systems should
be challenged by trying to energize them
while checking that no HV appears.
❒ When it is necessary to perform tests of
HV systems with the power ON, then the
Working Live procedure must be followed.
Refer to 1.6.3. “Working Live” on page 6 in
this bulletin for procedure.
❒ The test personnel shall always rehearse
the actions required in case of any possible
accident scenarios.
❒ Before beginning the Service procedure,
the test personnel shall remove all their
jewelry (including pierced ones), watches
and any electrically conductive objects on
them.

1.6.1. Vehicle Inspection
Prior to conducting any high voltage servicing,
the vehicle must be visually
inspected to ensure all systems are properly
maintained, paying special attention to
any evidence of fretting, chafing, or other
damage to HV cables or equipment.
1.6.2. Lockout/Tagout Procedure
The Lockout/Tagout procedure should be
followed as specified in the respective service
procedure.
When removing the lock and tag:
1. The locks and tags shall be removed by
the installer of the locks and tags or shall
be removed under her/his supervision.
2. If the installer of the locks and tags is not
available, then her/his supervisor:
a. Ensures that the installer of the locks
and tags is not in the facility.
b. Contacts the installer to inform her/him
that the locks and tags will be removed.
c. Reminds the installer of the lock and
tag removal when she/he resumes
work.
1.6.3. Working Live
To maximize safety, it is always important
to perform the maximum amount of HV
service in the de-energized state. Component
removal and installation must always
be performed in a de-energized state.
When it is necessary to test HV equipment
while energized or to verify whether HV is
present, the utmost care and safety procedures
must be used including:
❒ Wearing appropriate PPE including protector
gloves over top of the HV rubber
gloves.
❒ Ensuring all personnel, other than the
Checker and Monitor/Recorder, are clear
of the vehicle.
❒ Standing on HV insulated mat.
❒ Covering any energized HV components
not being immediately worked on with an
HV insulated mat to limit exposure to live
parts.
