5.3.1 Special application notes
• If terminals HV2 are connected in parallel to terminals HV1 (i.e. a galvanically connected HV system), the measured insulation resistance will be monitored including a +10 % offset
to the real insulation value.
• The HV2 terminals could be used for voltage monitoring at disconnected HV sections (e.g. voltage monitoring of a charging plug).
