Caution / Notice / Hint
WARNING:
- Before the following operations are conducted, take precautions to prevent electric shock by turning the power switch off, wearing insulated gloves, and removing the service plug grip from HV battery.
- Inspecting the high-voltage system
- Disconnecting the low voltage connector of the inverter with converter assembly
- Disconnecting the low voltage connector of the HV battery
- Disconnecting the low voltage connector of the DC/DC converter assembly
- To prevent electric shock, make sure to remove the service plug grip to cut off the high voltage circuit before servicing the vehicle.
- After removing the service plug grip from the HV battery, put it in your pocket to prevent other technicians from accidentally reconnecting it while you are working on the high-voltage system.
- After removing the service plug grip, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals. After waiting for 10 minutes, check the voltage at the terminals in the inspection point in the inverter with converter assembly. The voltage should be 0 V before beginning work.
Refer to PRECAUTION [11/2021 - 10/2023]
HINT:
Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.
*a Without waiting for 10 minutes - Make sure to insulate the high-voltage connectors and terminals of the HV battery with insulating tape after removing it.
If the HV battery stored without insulating the connectors and terminals, electric shock or fire may result
NOTE:
- After turning the power switch off, there may be a waiting time before disconnecting the auxiliary negative (-) battery terminal.
Refer to PRECAUTION [11/2021 - 10/2023]
- When disconnecting and reconnecting the auxiliary battery.
Refer to WORK PROCEDURE [11/2021 - 10/2022] , or refer to WORK PROCEDURE [10/2022 - ]
HINT:
When disconnecting and reconnecting the auxiliary battery, there is an automatic learning function that completes learning when the respective system is used.
