Grounding instructions
Audi charging systems must be grounded. If it
should malfunction or break down, grounding
provides a path of least resistance for electric
current to reduce the risk of electric shock. Audi
charging systems are equipped with a cord hav-
ing an equipment grounding conductor and a
grounding plug. The plug must be plugged into
an appropriate outlet thatis properly installed >

and grounded in accordance with all local codes
and ordinances.

Z\ WARNING
Improper connection of the equipment-
grounding conductor is able to result in a risk
of electric shock. Check with a qualified elec-
trician or serviceman if you are in doubt as to
whether the product is properly grounded. Do
not modify the plug provided with the product
- if it will not fit the outlet, have a proper out-

let installed by a qualified electrician.

Z\ WARNING
— Note the warnings for charging > A\ in
Charging on page 140.
— Before switching a cable, always unplug the
power cable from the socket.
— Only change cables in a dry environment.
— The Audi charging system may only be used
as a complete unit consisting of the power
cables, the control unit, and the vehicle ca-
ble. Depending on the country, the total
length of the power cable, control panel and
vehicle cable may be restricted, for example
to 24.6 ft (7.5 m) in the USA. We recom-
mend using only cables approved by Audi.

G) Tips
The power cable with the power connector for
industrial sockets and the Audi charging sys-
tem control unit are designed to work togeth-
er. Changing the power cable to another con-
nector type may reduce the available charging
power of the entire system.
