LocationDescription
Charge
port Under hood Connecting port for EVSE (Electric Vehicle
Supply Equipment) . Two ports are available:
Normal charge and quick charge (if so equipped) .
High-voltage cables Under hood and
undercarriage Orange-colored power cables carry high-voltage
current between each of the high-voltage
components.
Traction Motor Under hood Converts three-phase AC power to drive power
(torque) which propels the vehicle.
Inverter Under hood Converts the DC power stored in the high-voltage
battery to three-phase AC power and controls
motor torque (revolution) by regulating the motor
current.
Electric air
conditioner
compressor Under hood
Air conditioner compressor
Power Delivery
Module (PDM)
• On Board Charger
• DC/DC Converter
• High-voltage junction box (J/B) Under hood
The PDM includes an On Board Charger, DC/DC
converter and high-voltage junction box (J/B) .
The On Board Charger converts single-phase AC
power from a home power outlet to DC power
and increases the voltage in order to charge the
high-voltage battery.
The DC/DC converter reduces the voltage of the
high-voltage battery to provide power to the
12-volt battery in order to operate the vehicle’s
electric components (headlights, audio system,
etc.) .
The J/B provides electric power from the
high-voltage battery to all high-voltage parts of
the vehicle.
12-volt Battery Under hood A lead-acid battery that supplies power to the
low voltage devices.
Cabin heater Interior (This unit is
installed behind the
instrument panel) This is the electric heat source for the cabin
heater. It heats the interior of the vehicle.
High-voltage battery Undercarriage Stores and outputs DC power (Maximum voltage
398.4V) needed to propel the vehicle.
High-voltage battery
service disconnect Rear seat floor Isolates the battery from the rest of the
high-voltage electrical system.
Brake power supply
backup unit Cargo area (This unit
is installed behind a
trim panel to prevent
access) Power supply backup unit for the brake system.
It supplies power to the brake system if a
malfunction occurs in the 12-volt battery.

• If the charge connector is connected to the vehicle, remove it.
Refer to3-4.1 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 12-volt battery negative (-) terminal, wait at least three (3) minutes to discharge the air bag capacitor.
Even though the 12-volt 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 12-volt battery. Not doing so may result in serious injury or death from electrical shock.
• The 12V system will remain active even after the 12-volt 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.

3-5.1 SRS Air Bag System Components Location
The
SRS air bag system and inflators must not be cut as there is a risk of short circuit and unintentional
deployment of the SRS. However, the vehicle can be cut (except inflators) under the following conditions: • The front, side and curtain air bags have deployed.
• At least three (3) minutes have passed after the 12-volt battery negative (-) cable has beendisconnected and the high-voltage system has been shut down.

4-1 Jump Starting Procedures
1. If the booster battery is in another vehicle (B) , position the two vehicles (A and B) to bring their
12-volt batteries into close proximity to each other.
DO NOT allow the two vehicles to touch.
2. Apply the parking brake.
3. Push the P (Park) position switch to place the vehicle in the P (Park) position.
4. Switch off all unnecessary electrical systems (headlights, heater, air conditioner, etc.) .
5. Place the power switch in the OFF position (if possible) .
If the 12-volt battery is discharged, the power switch cannot be moved from the
OFF position. Connect the jumper cables to the booster vehicle (B) before pushing
the power switch.
6. Ensure vent caps are level and tight.
7. Connect jumper cables in the sequence as illustrated () . • Always connect positive (+) to positive (+) and negative (-) to body ground (for example,
as
illustrated) , not to the 12-volt battery
• Make sure the jumper cables do not touch moving parts in the motor compartment and that the cable clamps do not contact any other metal.
8. Start the engine of the booster vehicle (B) .
9. While the booster vehicle (B) engine is running, turn the power switch ON while pressing the brake pedal in order to place the LEAF in READY mode.
If the system does not start right away, push the power switch to the OFF position and wait
at

least 10 seconds before trying again. AAYIA0160ZZ
