Page: 138 / 293

To avoid hazardous situations, observe the
following:
R
Only connect the charging cable to a wall-
box:
-
which has been properly installed and
-
which has been inspected by a qualified
electrician
R
For safety reasons, only use charging
cables that have been tested and approved
by the manufacturer for charging the high-
voltage battery in an electric vehicle.
R
Never use damaged charging cables.
R
Do not extend the charging cable.
R
Never use adapters.
R
Observe the safety notes in the operating
instructions for the wallbox.
The vehicle's high-voltage electrical system is
under high voltage.
R
Do not handle high-voltage components or
the orange cables of the vehicle's high-volt-
age electrical system.
R
Do not touch high-voltage components or the
orange cables of the high-voltage electrical
system when a vehicle has been involved in a
crash.
R
Do not touch any damaged components or
damaged orange cables of the vehicle's high-
voltage electrical system.
R
Do not remove the covers of the high-voltage
electrical system components that are
marked with a warning sticker.
Notes on the charging cable
Handling the charging cable and charg-
ing cable controls
Do not leave the charging cable controls
(
Y
page 140) hanging loose from a mains
socket. Otherwise, this could result in a poor
contact with the mains socket and malfunctions
when charging the vehicle.
To ensure that the brackets within the charging
cable controls are not subjected to incorrect
loads, observe the following:
R
never lift or carry the controls by the charging
cable connector or the mains plug
R
to transport the charging cable, the coiled
part can be:
-
wrapped around the controls or
-
secured to the housing of the controls
Heat generated by the charging cable
and charging cable connector
Observe the important safety notes
(
Y
page 134).
During the charging process, the charging cable
and charging cable connector may heat up.
The charging cable and charging cable connec-
tor will only heat up within the permissible lim-
iting values, provided that:
R
the mains power supply and the charging
cable are not damaged
R
the instructions for handling the charging
cable and controls on the charging cable are
observed
Should the permissible heating temperature lim-
its be exceeded, have the mains power supply
checked.
Protection device against overvoltage
!
Voltage surges in the mains supply can dam-
age the vehicle. The vehicle is therefore
equipped with a device which protects it from
voltage surges in the mains supply. This
device may be triggered during severe thun-
derstorms, for example, and may lead to the
building's fuse being tripped and an interrup-
tion in the power supply. These functions pro-
tect the vehicle. After the building fuse is
switched on again, the charging process
resumes automatically. Following an interrup-
tion in the power supply without tripping of
the building's fuse, it may take up to
15 minutes for charging to resume automat-
ically.
Switch on the building's fuse again after the
protection device against overvoltage has been
triggered. Otherwise, the charging process can-
not be continued. The high-voltage battery will
not be charged and you may not be able to drive
the vehicle.
