2017 NISSAN LEAF harness

• The colors of the high-voltage harnesses and connectors are all orange. Orange
High-
voltage labels
are applied to the high-voltage battery and other high-voltage devices. Do
not touch the high-voltage 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.
• 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.
• The high-voltage battery retains high-voltage at all times. Personal Protective
Equipment
(PPE) must always be worn when touching or working on high-voltage
components to avoid risk of electrical shock and severe personal injury or death.
• 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 high-voltage battery packs away from rain to avoid electric shock.
•

Do not heat removed battery packs higher than 158° F (70° C) . There is the possibility of a malfunction occurring if the vehicle is changed to READY
status while the service plug is removed.
