Thank you for the detailed report — trying both dispensers and seeing no error on the vehicle is very useful diagnostic information.

**Likely cause: a fault on the charger side, not your vehicle.**

Since "Charging stopped due to safety device activation" (error code 2) appeared repeatedly on both the left and right dispensers while your Nissan Leaf shows no errors, this pattern points to a problem with the charger itself rather than the car. We will investigate the unit and contact you once we have identified the cause (see /sources/en/runbooks/charging-troubleshooting.md:106).

**Before you give up on this station, two quick checks worth one more try:**

- Make sure the connector is inserted until it locks (clicks), the shift is in P, the vehicle power is OFF, and no vehicle settings (e.g. charge timers) interfere — then retry using the "Charge again" button in the app. Safety-device errors can occasionally be temporary (charging-troubleshooting.md:488).
- If the opposite dispenser is free, you can use it on the same reservation — no rebooking is needed within your reserved time slot.

**If it still fails:**

- Please use another charging station today; we can't promise same-day recovery on a faulty unit.
- Billing is pay-as-you-go, so if you were unable to charge, you won't be charged for the failed attempts.

**To help us investigate, please share:**

- Your user ID, the station name, and the date/time of the attempts
- The charger's LED color during the errors
- Whether you were in the vehicle when the error appeared

We're sorry for the inconvenience, and we'll follow up with you as soon as we've identified the cause.

ご不便をおかけしており、申し訳ございません。お問い合わせの状況を確認いたしました。

**原因について**
左右どちらの充電器でも「安全装置が働いた為中止しました」(エラーコード2)が繰り返し表示され、車両側(日産リーフ)にエラーが出ていない場合、**充電器本体側の不具合の可能性**があります(/sources/ja/runbooks/charging-troubleshooting.md:102-106)。車両側に原因が見当たらないため、充電器側で確認・調査をさせていただき、原因が分かり次第折り返しご連絡いたします。

**今のところのお願い**
- 大変恐れ入りますが、本日は別の充電ステーションのご利用をご検討ください。
- なお、まれに一時的な要因で安全装置が作動するケースもあります。コネクターのロック状態、シフトがPレンジに入っているか、車両の充電タイマー等の設定、電源OFFを確認のうえ、アプリの「再度充電する」ボタンから再試行いただくことも可能です(/sources/ja/runbooks/charging-troubleshooting.md:484-488)。ただし左右とも同じエラーが再現している状況ですので、充電器側の調査を優先して進めます。

**調査のためのご協力のお願い**
原因究明を進めるため、以下の情報をご教示いただけますと幸いです。
- ユーザーID
- 車両情報(車種・年式など)
- 充電日時・ご利用の拠点(ステーション名)
- 左右どちらかの区別(今回のように両方の場合はその旨)
- 充電器のLEDの色
- アプリ/車内表示の内容
- 充電中に車内にいたかどうか
- 再充電の可否

お手数をおかけしますが、上記情報をいただけましたら担当部署にて確認し、結果をお知らせいたします。

Output

**Likely cause: a fault at the charger itself, not your Leaf.**

The pattern you describe is the key diagnostic signal:

- Error code 2 ("Charging stopped due to safety device activation") repeated on **both** the left and right dispenser (1 attempt left, 3 attempts right).
- **No error shown on the vehicle.**

When the same safety-stop error recurs on both dispensers while the vehicle reports nothing wrong, the guidance is that this points to a problem with the charger unit rather than the car or your account, and it needs to be checked on our side — the cause can't be confirmed from your end alone (en/runbooks/charging-troubleshooting.md:102, en/runbooks/charging-troubleshooting.md:106).

For contrast, when a safety-device stop is triggered at the vehicle's request (e.g. codes 187/200), it is often temporary and clears after checking the connector lock, shift in P, vehicle timer settings and power off, then retrying with the app's "Charge again" button — and usually the opposite dispenser then works (en/runbooks/charging-troubleshooting.md:488). That self-recovery route doesn't apply in your case, since both sides fail identically.

**What to do now**

1. Don't keep retrying at this unit — move to a different charger or station for today's charging.
2. If the connector is stuck after the session stopped, the red emergency-stop button can be pressed to release it; once released, gently turn the button to the right to return it to its original position so the next customer can use it (en/runbooks/charging-troubleshooting.md:117-118 area, entry CS-012).
3. If you were charged for a session that did not actually deliver power, contact us for a refund (en/runbooks/charging-troubleshooting.md:139).

**Details needed so the cause can be investigated**

Please send: your user ID, vehicle info, date and time of each attempt, station/location, which side (left/right), the LED colour on the charger, the exact error code, what was shown in the app and in the car, whether you were inside the car, and whether the app's "Charge again" button worked (en/runbooks/charging-troubleshooting.md:490).

One caveat on expectations: I can flag this for investigation, but I can't confirm that a fault report has been filed or that the charger has been taken out of service — that requires confirmation from the authorised system/operator. Also note that this guidance comes from an internal operations runbook; the public Help Center in this workspace has no entry covering error code 2, so the charger-side diagnosis is based on that runbook rather than a published policy page.

Output

ご提示いただいたエラーコード2(安全装置作動)は、充電制御系やバッテリー管理系に問題が発生している可能性を示しています。車両側のエラーログがない場合でも、充電器・ケーブル・コンセント側の問題、または高電圧回路の絶縁不良や通信異常が考えられます。

まず、別の充電器や別のコンセントで試すことで、充電インフラ側か車両側かの切り分けを行ってください。また、バッテリーの温度が高すぎる場合や、急速充電・普通充電のいずれでも発生する場合は、車載充電器(OBC)やBMS(バッテリー管理システム)の不具合が疑われます。

エラーが消えず、別の充電環境でも同じ現象が発生する場合は、高電圧回路の絶縁耐圧テストや診断機器による詳細な通信ログの確認が必要なため、日産ディーラーまたは専門の電気自動車整備工場での点検を強く推奨します。
