The￿high-voltage￿connection￿can￿be￿replaced￿as￿a￿separate￿component,￿just￿like￿all￿other￿components
of￿the￿high-voltage￿battery￿unit.
The￿diagnosis￿and￿repair￿of￿the￿high-voltage￿components￿is￿only￿allowed￿in￿a￿retail￿service
center￿that￿has￿qualified￿and￿certified￿service￿technicians.￿These￿technicians￿must￿have
completed￿the￿ST1403b￿I01￿High￿Voltage￿Battery￿and￿Maintenance￿instructor￿led￿course￿and
successfully￿passed￿the￿hands￿on￿certification.
Low-voltage￿connections
There￿are￿two￿low-voltage￿connections￿at￿the￿high-voltage￿battery￿unit￿of￿the￿I01:
1 Connection￿for￿lines￿to￿the￿SME￿control￿unit
2 Connection￿for￿the￿activation￿of￿the￿combined￿expansion￿and￿shutoff￿valve
The￿connection￿for￿the￿SME￿control￿unit￿has￿the￿following￿lines:
• Voltage￿supply￿of￿the￿SME￿control￿unit￿with￿terminal￿30F￿and￿ground￿connection
• Terminal￿30C￿for￿the￿voltage￿supply￿of￿the￿electromechanical￿switch￿contactors
• Wake-up￿line￿from￿the￿BDC
