Although�the�convenience�charging�electronics�works�at�a�high�degree�of�efficiency�of�well�over�90%,
active�cooling�is�required�at�full�performance.�For�this�reason�it�is�integrated�in�the�cooling�circuit�of�the
electric�motor.
In�addition�to�the�voltage�conversion�and�energy�provision,�the�convenience�charging�electronics�also
assumes�safety�functions�which�protect�the�customer�and�Service�employee�from�the�dangers�of
electricity.�Nevertheless,�the�following�applies:
The�convenience�charging�electronics�is�a�high-voltage�component�
Only�qualified�Service�employees�can�work�on�the�convenience�charging�electronics�while�observing
the�repair�instructions.
Before�working�on�the�convenience�charging�electronics,�it�is�essential�to�observe�the�electrical�safety
rules.
Similar�to�all�high-voltage�components,�the�convenience�charging�electronics�can�only�be�replaced�in
Service�if�required,�it�cannot�be�opened�or�repairs.
The�manufacturer�of�the�convenience�charging�electronics�is�"Meta�System".
Connections
The�connections�at�the�convenience�charging�electronics�can�be�divided�into�four�categories:
•
Low-voltage�connections
•
High-voltage�connections
•
Connection�for�potential�compensation�line
•
Connections�for�coolant�lines.
