service INFINITI M HYBRID 2013 Dismantling Guide

5. Storing the Vehicle
If
the M35h HYBRID needs to be stored or left unattended, the high voltage system must be shut down by
removing the service plug (refer to Alternate Procedure 2) and a sign put on the vehicle indicating it is a
hybrid

vehicle with high voltage dangers. For example: AAYIA0020GB

6. Dismantling Information
Removal
or repair of the high voltage battery requires special tools and specific training. INFINITI strongly
recommends that only certified INFINITI retailer technicians perform these operations.
6-1 Precautions for Handling High Voltage Lithium-ion (Li-ion) Battery • Because M35h HYBRID contains a high voltage (Li-ion) battery, there is the risk of
electric
shock, electric leakage, or similar accidents if the high voltage components or
vehicle is handled incorrectly. Be sure to follow the correct work procedures when
performing inspection and dismantling.
• The colors of the high voltage harnesses and connectors are all orange. Orange
High
V

oltage labels are applied to the Li-ion battery and other high voltage devices. Do not
touch the Li-ion battery or other high voltage devices without always wearing appropriate
PPE.
• Clearly identify the persons responsible for high voltage work and ensure that other
persons
do not touch the vehicle. When not working, cover high voltage parts with an
insulating cover sheet and sign or similar item to prevent other persons from contacting
them.
• The high voltage battery retains high voltage at all times.
• Be sure to always wear appropriate PPE before beginning work on the high voltage
system.
• If it is necessary to touch any of the high voltage harnesses or components you must
always
wear appropriate PPE and properly shut-down the high voltage system by
removing the service plug.
• Be sure to remove the service plug in order to shut-down the high voltage system
before
performing inspection or dismantling of high voltage system harnesses and parts.
• Be sure to put the removed service plug in your pocket and carry it with you so
another
person does not accidentally reinstall it while work is in progress.
• Immediately insulate disconnected high voltage connectors and terminals with
insulated
tape.
• 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.
• Because this vehicle uses components that contain high voltage and powerful
magnetism,
do not carry any metal products which may cause short circuits, or any
magnetic media (cash cards, credit cards, etc.) which may be damaged when working on
the vehicle.
• Keep removed Li-ion battery packs away from rain to avoid electric shock.
• If the vehicle is heavily damaged, for example the Li-ion battery is deformed, broken,
or

cracked; appropriate PPE must always be used at all times to avoid electrical shock.
• Do not heat removed battery packs higher than 158° F (70° C) .

There is the possibility of a hybrid system malfunction occurring if the vehicle is changed to
READ
Y status while the service plug is removed.

PPE (Personal Protective Equipment) and Insulated Tools
6-2.1 PPE (Personal Protective Equipment) Protective Wear Control
Perform an inspection of the PPE items before beginning work. Do not use any damaged PPE items.
6-2.2 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)
6-2.3 Insulated Tools
When performing work at locations where high voltage is applied (such as terminals) , use insulated tools
meeting 1,000V/300A specifications.
