Needed material
For the Overload Protection additional
installation material is needed. The table
is listing this material with respect to the
number of phases of the local installation.
Install Overload Protection
1. Install and prepare the CT coils.
a. Place one CT coil per phase at the point
of facility current measurement. Install
the CT coils according to the CT coil
manufacturer’s instructions to ensure
proper functionality.
b. Shorten the CT coil’s signal wires as
much as possible while leaving them
long enough to connect to the data
cable.
c. Strip the signal wires to a length
according to the splicing connector’s
specification.
2. Prepare the data cable and connect to
CT coil.
a. Use one pair of the data cable’s signal
wires per installed CT coil. Strip these
wires to a length according to the spli-
cing connector’s specification.
b. Shorten the rest of this data cable so
that the signal wires used are long
enough to be connected to the CT coil’s
signal wires.
c. Connect each signal wire of the CT coil
with one of the wires of the data cable’s
signal wire pair, using the splicing con-
nector.
3. Route the data cable and insert into the
Audi Wallbox.
For further details refer to chapter Mount
main assembly onto wall bracket.
a. Route the date cable from the CT coil to
the Audi Wallbox.
b. Insert the data cable into the Audi Wall-
box via one of the provided knockouts
of the Audi Wallbox and the provided
cable gland.
c. Make sure to have at least 80 mm of
data cable available on the inside of the
Audi Wallbox, after the cable gland has
been tightened.
4. Connect the data cable to the Audi Wall-
box.
For further details refer to chapter Assemble
wallbox.
a. Strip the data cable’s outer insulation
by 50 mm.
b. Shorten the data cable’s EMC shield and
protect it from undesired contact with
other electric parts, with respect to the
setup used..
c. Strip the signal wires by 7 mm.
d. Insert the signal wires into the MCVR
1.5/3-ST-3.81 connector and secure the
wires using a screwdriver. Make sure
that the signal wires will be attached
to the center and right pin of the Audi
Wallbox's female connector.

It is recommended to use a data cable
with at least a single/foil shielded data
cable. In order to reduce EMC noise to a
minimum, a double/foil-braid shielded
data cable with twisted wire pairs (S/FTP)
should be used.
