    Solo i tecnici che hanno completato tutti i corsi di certificazione richiesti sono autorizzati a eseguire questa procedura. Tesla raccomanda ai tecnici di fornitori di terze parti di seguire una formazione equivalente prima di svolgere la presente procedura. Per maggiori informazioni sui requisiti dei Tecnici Tesla, o per le descrizioni degli argomenti richiesti per i tecnici di fornitori terzi, vedere i Requisiti per certificazioni HV. Ogni volta che si maneggia un raccordo, una barra di distribuzione o un cavo ad alta tensione è necessario indossare idonei dispositivi di protezione individuale (DPI) e guanti isolanti per l'alta tensione con classe di protezione minima 0 (1000 V). Per ulteriori informazioni sulla sicurezza, fare riferimento alle Note tecniche relative ai rischi dell'alta tensione TN-15-92-003, "High Voltage Awareness Care Points".

    Avvertenza
    Assicurarsi che i guanti per l'alta tensione non siano scaduti.
    • Nord America: I guanti per l'alta tensione possono essere utilizzati fino a 12 mesi dopo la data di test stampata sui guanti stessi, ma solo 6 mesi dopo il primo utilizzo anche se i guanti ancora rientrano nel periodo di 12 mesi. Se i guanti non sono stati messi in servizio durante il periodo di 12 mesi successivo alla data di test, devono essere nuovamente testati prima di essere messi in servizio.
    • Europa: I guanti per alta tensione di Classe 0 (1000 V) non hanno una data di scadenza e possono essere utilizzati se superano la valutazione pre-utilizzo e l'ispezione periodica.
    • Asia Pacifico: Attenersi alla data di scadenza indicata dal produttore dei guanti per l'alta tensione e:
      • o Solo per la Cina: Testare i guanti ogni 6 mesi secondo GB/T 17622.

    17. At the charge port, use the Hioki resistance meter to measure the resistance between the charge port busbar lead and the charge port busbar stud. Also perform this test on the other lead and stud.
      Informational PurposesAn informational icon, calling your attention
      Note
      The acceptable resistance is between 0.050 mΩ (50 μΩ) and 0.270 mΩ (270 μΩ). If the measured resistance is above 0.270 mΩ (270 μΩ), there is too much resistance in the High Voltage joint. Remove the fastener, clean areas with isopropyl alcohol, install fastener back and test again, as appropriate.
      Informational PurposesAn informational icon, calling your attention
      Note
      If the resistance is lower than 0.050 mΩ (50 μΩ), reposition the probes and measure again. If after 4 attempts the resistance is consistently lower than 0.050 mΩ (50 μΩ), the test has passed; continue to the next step.

      The acceptable resistance is between 0.050 mΩ (50 μΩ) and 0.195 mΩ (195 μΩ). If the measured resistance is above 0.195 mΩ (195 μΩ), there is too much resistance in the High Voltage joint.
