3-3 Personal Protective Equipment (PPE) and Insulated Tools
3-3.1
Personal Protective Equipment (PPE) Protective Wear Control
Perform an inspection of the Personal Protective Equipment (PPE) items before beginning work. Do not use
any damaged PPE items.
3-3.2 Daily Inspection
This inspection is performed before and after use. The worker who will be using the items should perform
the inspection and check for deterioration and damage. • Insulated rubber gloves should be inspected for scratches, holes and tears. (Visual check and airleakage test)
• Insulated safety boots should be inspected for holes, damage, nails, metal pieces, wear or other problems on the soles. (Visual check)
• Insulated rubber sheet should be inspected for tears. (Visual check)
3-3.3 Insulated Tools
When performing work at locations where high voltage is applied (such as terminals) , use insulated tools
meeting 1,000V/300A specifications.
3-4 High Voltage System Shut-Down Procedures
Once the high voltage battery is properly discharged, any of the following procedures can shut down and
isolate the high voltage system. The dismantling operation can only begin after shutting down the high
voltage system. If the vehicle is heavily damaged, for example the Li-ion battery is deformed, broken or
cracked, appropriate Personal Protective Equipment (PPE) must always be used and the Li-ion battery and
high voltage components must not be touched. • Failure to properly shut down the high voltage system before the dismantling
procedures
are performed will result in serious injury or death from electrical shock. To
prevent serious injury or death, NEVER touch high voltage harnesses or components
without always wearing appropriate Personal Protective Equipment (PPE) . PPE
must always be worn when touching or working on high voltage components
• When contact with high voltage components or high voltage harnesses is
unavoidable,
or when there is risk of such contact, you must always wear appropriate
PPE. PPE must always be worn when touching or working on high voltage
components.
DG–16

• If the charge connector is connected to the vehicle, remove it. Refer to
3-3.1 Removing
the
Charge Connector (DG–18) .
• The vehicle contains parts that contain powerful magnets. If a person who is wearing a
pacemaker
or other medical device is close to these parts, the medical device may be
affected by the magnets. Such persons must not perform work on the vehicle.
• Be sure to verify that the READY indicator is off and the high voltage system is
stopped.
•

After the high voltage system is shut down, please wait at least ten (10) minutes for
complete discharge of the high voltage capacitor. While waiting, do not operate any vehicle
functions.
• After shutting down the high voltage system and removing the 12V battery negative (-) terminal, wait at least three (3) minutes to discharge the air bag capacitor. Even though the
12V battery negative (-) is disconnected, the Supplemental Restraint System (SRS) air
bag maintains voltage at least three (3) minutes. During this time, there is a possibility of
sudden SRS air bag inflation due to harness short circuit or damage and it may cause
serious injuries.
• Always shut down the high voltage system before disconnecting the 12V battery. Not doing so may result in serious injury or death from electrical shock.
• The 12V system will remain active even after the 12V battery negative (-) terminal is removed while the high voltage system is active. The high voltage system is active during
any of the following conditions:
– charging indicator is turned ON
– READY indicator is turned ON
Refer to 1-1.2 Interior Component Location (DG–7)
for location of these indicators. This is
because

DC/DC converter will not shut down and power will be supplied to the 12V system
and high voltage system continuously.
DG–17

3-4.2 Indications the High Voltage System is ON
1. If the READY indicator is ON, the high voltage system is active.
2.

The high voltage system is active if any charge indicator
is ON (blue LEDs on top of the instrument panel) .
Before disconnecting the 12V battery terminal, if necessary, lower the windows, unlock the doors, and open
the rear hatch as required. Once 12V battery is disconnected, power controls will not operate.
3-4.3 Powering Down the High Voltage System
The high voltage system can be shut down with any 1 of the following procedures: • Turn OFF the power switch anddisconnect the 12V battery. Refer to
3-3.4 Primary
Procedure

(DG–20) .
•

Remove the fuses for the high voltage control system and disconnect the 12V battery. Refer to
3-3.5 Alternate Procedure 1 (Remove Fuses) (DG–21) .
•

Remove the service plug and disconnect the 12V battery. Refer to 3-3.6 Alternate Procedure 2
(Remove

Service Plug) (DG–24) .
3-4.4

Primary Procedure
1. Check the READY indicator status. If it is ON, the high voltage system is active.
2.

Place the selector lever in the Park (P) position.
3. Press the power switch once to turn OFF the high voltage system. Then verify whether the READY indicator is OFF and continue to the next steps to
open

the hood for 12V battery negative cable access.
If the READY indicator does not turn off, refer to
Alternate Procedure 1 (Remove Fuses) (DG–21)
4. If possible, keep the Nissan Intelligent Key® at least 5 meters
(16 feet) away from the vehicle. AAYIA0155ZZ

3-4.6 Alternate Procedure 2 (Remove Service Plug)
• Do not remove the service plug without always wearing appropriate Personal
Protective Equipment (PPE) to help protect the dismantler from serious injury or death
by electrical shock.
• Immediately cover the service plug socket with insulated tape. The Li-ion battery
retains
high voltage power even when the service plug is removed. To avoid electric
shock, NEVER touch the terminals inside the socket. To avoid unintended reinstallation and risk of electrical shock and severe personal injury
or

death, the dismantler should carry the service plug on his/her person while work is in
progress.
1. Insert a suitable tool (1) under the RH rear corner of theaccess trim cover located on the floor behind the center
console. Pry up (2) and remove.
NOTE: : Arrow in illustration depicts vehicle front
direction.
2.

Remove the 10 mm access cover bolts (1) and remove
the cover (2) .
NOTE: : Arrow in illustration depicts vehicle front

3-5 Cutting the Vehicle Body
• Do not cut into high voltage related areas to avoid severe personal injury or death.
• Do not cut into the Li-ion battery to avoid severe personal injury or death.
• When removing parts, NEVER touch the high voltage parts or the insides of the
exposed orange-colored high voltage cables to avoid severe personal injury or death.
Personal Protective Equipment (PPE) must always be worn when touching or
working on high voltage components. • To avoid unintended reinstallation and risk of electrical shock and severe personal injury
or
death, the dismantler should carry the fuses or service plug on his/her person while
work is in progress.
• Do not cut air bag parts to avoid unintended deployment of the air bags and the risk of severe personal injury or death.
If at least ten (10) minutes have passed since the dismantler shut down the high voltage system (refer to
3-3 High Voltage System Shut-Down Procedures (DG–16)) , then the dismantler can cut the vehicle except for the Li-ion battery.
DO

NOT cut the Li-ion battery due to possible electrocution risk and electrolyte solution
leakage.
DG–26
