2.￿Important￿Notes
2.2.￿Safe￿working￿practices￿for￿working￿on￿a￿high-voltage￿system
Before￿working￿on￿high-voltage￿components￿of￿the￿I01,￿it￿is￿essential￿to￿observe￿and￿implement￿the
electrical￿safety￿rules:
1 The￿high-voltage￿system￿must￿be￿disconnected￿from￿the￿supply
2 The￿high-voltage￿system￿must￿be￿provided￿with￿a￿safeguard￿to￿prevent￿unintentional￿restarting
3 The￿safe￿isolation￿of￿the￿high-voltage￿system￿must￿be￿verified
The￿following￿chapters￿provide￿brief￿descriptions￿on￿how￿to￿implement￿the￿electrical￿safety￿rules￿in￿the
I01.
2.2.1.￿Preparations
Prior￿to￿beginning￿any￿work,￿the￿vehicle￿must￿be￿secured￿against￿rolling￿away￿(engage￿the￿parking￿lock
of￿the￿transmission￿and￿activate￿the￿parking￿brake).￿Terminal￿15￿and￿terminal￿R￿must￿be￿switched￿off.
Disconnect￿any￿connected￿charging￿cables.￿The￿vehicle￿should￿be￿in￿"rest￿state".
2.2.2.￿Disconnect￿the￿high-voltage￿system￿from￿the￿supply
The￿high-voltage￿system￿in￿the￿I01￿is￿disconnected￿from￿the￿supply￿with￿the￿high-voltage￿safety
connector.￿To￿disconnect￿from￿the￿supply,￿the￿connector￿must￿be￿pulled￿from￿the￿relevant￿socket.￿This
interrupts￿the￿circuit￿of￿the￿high-voltage￿interlock￿loop.
