2-3 High Voltage Circuit Shut-Off System
The high voltage can be shut off by the following methods:
Service plug Positioned in the center area of the Li-ion battery, this shuts off output high
voltage when manually removed.
System main relay Controlled by the power switch, this relay, which is controlled by the 12V
system, shuts off the high voltage from the Li-ion battery.
Emergency shut-off sys-
tem In the case of a collision (front and side collisions in which the air bags are
deployed, certain rear collisions) or certain system malfunctions this system
may shut off the high voltage from the Li-ion battery.
Charging connector Some of the high voltage components are activated during charging. Remove
the charging connector to deactivate these components.
2-4 Preventing Electrical Shock
1. If it is necessary to touch any of the high voltage harnesses or components, you must always
wear appropriate PPE (refer to 3-1 Preparation Items ) and shut off the high voltage system by
referring to 3-3.1 High Voltage System Shut-Down Procedure .
2. To avoid the risk of electrocution, do not touch the inside of the Li-ion battery unless appropriate
PPE is worn even after shutting off the high voltage system. The Li-ion battery maintains charge
even though the high voltage system is shut down.
3. Cover any damaged high voltage components with insulated tape.
2-5 Emergency Medical Equipment
The high voltage system should not interfere with emergency medical equipment which must be used in or
near the vehicle at an accident scene.
