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.
