IMPORTANTElectrical fuses in high-voltage battery 

There are replaceable fuses in the high-voltage battery (electrical fuse 750, electrical fuse 751, and electrical fuse 752). These are placed under a removable cover (with interlock contact breaker point), and located in the electric circuit behind the contactor.

In this way the electrical fuses for orderly power disconnect are not under voltage.
