Similar�to�all�high-voltage�components,�the�housing�of�the�convenience�charging�electronics�must�be
connected�electrically�to�ground.�Only�then�can�the�automatic�monitoring�of�the�isolation�resistance
work�properly.�Also�with�the�convenience�charging�electronics,�the�protective�earth�of�the�AC�voltage
network�at�the�charging�socket�is�also�connected�to�ground.�Protective�earth�(PE)�and�housing�of�the
convenience�charging�electronics�must�have�the�same�potential,�so�that�any�isolation�fault�can�be
identified�on�the�AV�voltage�side�of�the�AC/DC�converter.�The�housing�of�the�KLE�is�connected�to�the
Drive�module�using�four�screws�for�this�purpose.
