to the housing or charging cable. #
Atcharging stations without a pre-

Obse rveth e on-site operator's instructions for
th ech arging station.
The charging cable forth eve hicle must not be
longer than 30 m due tothe legal requ irements
in some countries. This is topreve ntthe inter fer‐

thech arging cable may be routed under‐

operator if this is the case before charging the
high-voltage batter y.
