경고

This procedure verifies that high voltage power is no longer available to high voltage components (A/C compressor, inverters, etc). Perform this procedure before servicing high voltage components.

경고

고전압에 노출되는 절차를 수행하기 전에 작업자에게 모든 장신구(시계, 팔찌, 반지, 목걸이, 귀걸이, ID 태그, 피어싱 장신구 등)를 벗으라고 하고 주머니에서 모든 물건(열쇠, 동전, 펜, 연필, 공구, 패스너 등)을 꺼내 놓으십시오.

경고

절차를 수행하기 위해서 시력 교정 안경이 필요한 경우, 시력 교정 안경을 머리에 단단히 고정하여 떨어지지 않게 하십시오.

경고

Always wear High Voltage (HV) gloves and safety glasses when handling any high voltage component, including test equipment. Before each use, test gloves using an authorized glove tester and verify that the testing date on the gloves has not expired.

경고

All repair and operating instructions should be reviewed and understood before working on Tesla vehicles, associated components, or associated repair equipment.

경고

Assume that high voltage is present at all times when working on a Tesla vehicle, associated high voltage components, or associated high voltage test equipment until proven otherwise. Be aware that energy states can change during testing, so always use caution.

경고

Always have an electrical safety hook in the area when working with HV components. Electrical safety hooks are used to remove an injured person from a live high voltage circuit without risking additional injury.

경고

Use a high voltage digital multimeter to check for the presence of high voltage on both sides of the connector every time a high voltage connector is disconnected.

경고

일부 지역에서는 이 절차를 위해 전압 부재 테스터(VAT)가 필요하며 멀티미터 사용은 허용되지 않습니다. 항상 현지 또는 지역별 공구 규정을 준수하십시오.

경고

Make sure that the insulation meter and leads are capable of handling at least 500V DC.

경고

Obey all instructions when using test equipment or servicing a Tesla vehicle or associated high voltage components. If repair instructions are not clear or if there are any questions about how to use the test equipment, escalate a Toolbox session before proceeding.

경고

If any test equipment fails to operate as expected, do not attempt to diagnose or repair the vehicle. Follow the appropriate lock out – tag out procedure for the equipment, notify your manager.

경고

When using test equipment, make sure that all cables are connected before turning equipment on or otherwise initiating use.

경고

High voltage is present on battery recovery chargers whenever the HV LEDs are lit. However, indicators and LEDs can fail. Do not assume that if an LED is not lit no high voltage is present. Assume high voltage is present at all times until proven otherwise by use of a multimeter.

경고

모든 필수 인증 교육을 완료한 기술자만 이 절차를 수행할 수 있습니다. Tesla는 타사 서비스 제공업체 기술자가 이 절차를 수행하기 전에 동등한 교육을 받을 것을 권장합니다. Tesla 기술자 요구 사항에 대한 자세한 내용이나 타사 기술자에 대한 분야별 설명은 HV Certification Requirements를 참조하십시오. 고전압 케이블, 버스바 또는 피팅을 다룰 때에는 항상 적합한 개인 보호 장비(PPE)와 클래스 0(1000V)의 최소 정격을 갖는 절연 HV 장갑을 착용해야 합니다. 추가 안전 정보는 기술 노트 TN-15-92-003고압 인식 주의 사항을 참조하십시오.

참고

This procedure is for 구조용 팩 5 seat vehicles. For instructions on checking HV disablement on 구조용 팩 이외 5 seat vehicles, see 차량 HV 비활성화 절차. For instructions on checking HV disablement on 구조용 팩 이외 7 seat vehicles, see 차량 HV 비활성화 절차(7인승)

Open all the doors and lower all the windows.
Remove the rear underhood apron. See 후드 내 에이프런 - 후면(탈거 및 교체).
Disconnect 12V/LV power. See 12V/LV 전원(연결 해제 및 연결).
Set the current clamp to measure voltage , and then measure the voltage across the 12V/LV auxiliary battery terminals using the test probes.

참고
For LV (Li-Ion) auxiliary battery: if the voltage across the battery terminals is 0, the battery may have switched off internally. Use a 12V Lead Acid battery for testing. For mobile technicians: use the 12V Lead Acid battery in the Mobile Service vehicle.

경고
For LV (Li-Ion) auxiliary battery: if the voltage across the battery terminals is less than 13 volts or greater than 16 volts, the current clamp is not measuring reliably and must not be used.

경고
For 12V (Lead Acid) auxiliary battery: if the voltage measured is less than 10 volts or greater than 14 volts, the current clamp is not measuring reliably and must not be used.
Remove the mid aero shield panel. See 패널 - 에어로 실드 - 후면(탈거 및 교체).
Remove all items from pockets and ensure not wearing metal items.
Inspect HV insulating gloves.

참고
Check gloves for damage prior to use, Refer to service document TN-15-92-003 R1, for information on inspecting HV gloves.
Put on HV insulating gloves, leather outer gloves, and safety glasses.

경고
Continue to wear the gloves until instructed to remove them.
Power on the current clamp meter, and then zero out the meter for measurment.

경고
Make sure to set the clamp meter to measure DC amps ("Adc").
Install the current clamp meter onto one cable of the rear drive unit HV harness.

참고
Make sure the meter is facing the correct direction.
Measure the current in the HV cable.
- If the current is within the range of -0.5 A to 0.5 A, continue to the next step.
- If the current is outside the range of -0.5 A to 0.5 A, for example -0.8 A or 1.3 A, re-perform the LV power disconnect procedure. See 12V/LV 전원(연결 해제 및 연결). If the measurement is still outside the range of -0.5 A to 0.5 A, escalate for assistance.
  경고
  DO NOT DISCONNECT any HV harness when the current measurement is outside the range of -0.5 A to 0.5 A.
Disconnect the RDU HV cable from the HV battery.

참고
Release the locking tab, and then rotate the release lever upward to disengage the connector. Do not force the release lever up. Ensure the alignment tabs on the RDU header are not damaged.

Verify no high voltage at the rear drive unit HV header.
