General requirements of the installation site
Your Mercedes-Benz Wallbox Home is an electrical device and is therefore subject to particular requirements for indoor and
outdoor installation. In selecting the installation site, you must consider the following points:
• Observe all local regulations for electrical installations, e.g. regarding fire protection and accident prevention.
• The Wallbox must be installed where it is freely accessible to all authorized users.
• A parking spot must also be planned for in front of the Wallbox so that the vehicle's charging
connector can at all times be reached with the fixed charging cable of the Wallbox.
• The recommended installation height is 120 to 140 cm from the floor to the lower edge of
the housing. This recommendation may be adjusted upwards or downwards depending on
local conditions. Sufficient air circulation must be ensured at the installation site so that the
Wallbox is cooled during operation: Always observe the allowed operating temperatures (see
“Technical specifications” on page 23).
• To ensure the safe operation of the Wallbox, minimum clearances of 50 cm must be ob-
served on all sides of the housing.
• The mounting area must have an even surface that provides sufficient stability for installing
the Wallbox.
• The required mounting area for the Mercedes-Benz Wallbox Home is at least 440 x 330mm
(H x W). The entire rear surface of the Wallbox must be in contact with the mounting sur-
face.
• In general, the Mercedes-Benz Wallbox Home is engineered for operation in high ambient
temperatures. However, it must always be ensured that the maximum operating temperature is not exceeded through exter-
nal influences such as direct sunlight or similar.
• The Wallbox meets the requirements for outdoor installation. Outdoors, it is recommended that the Wallbox is only installed
in a covered location that provides sufficient protection from the weather.
Requirements for the power supply cable
The following standards must always be taken into account for the electrical installation of the Mercedes-Benz Wallbox Home:
• All regulatory requirements for low voltage installations according to IEC 60364-1 and IEC 60364-5-52 apply.
• The A0009067408 model variant is intended for connection to and operation on rated voltages of 230V (phase-neutral,
single phase) or 400V (phase-phase, 3-phase) and 50Hz. The A0009067508 model variant is designed for connection to
and operation on a rated voltage of 230V (phase-neutral, single phase) and 50Hz.
• The installation site must offer a sufficiently dimensioned power supply cable according to HD 60364-7-722:2012: This

aspects (such as cable length, material, cabling method etc.). The terminal blocks in the
Wallbox are designed for cable dimensions from 1.5mm2to 16mm2.
• The power supply cable may be installed above or below the wall surface. If the power
supply cable is installed above-surface, a cable guide is provided at the back of the hous-
ing to guide the cable to the terminals area of the housing base.
• The power supply for the Wallbox must always be protected by its own MCB (rated cur-
rent depending on the power supply and Wallbox settings, but no more than 32 A). Please
always observe the applicable national requirements regarding the selection of the MCB.
• If you want to take the Wallbox out of operation, switch the upstream domestic MCB and
the internal RCCB to the 0(OFF) position.
• Please always ensure that the installation requirements listed in this manual are complied with. Disregard or actions to the
contrary may lead to severe, even fatal injury by electric shock. In addition, in case of contravention of the notices given,
the proper operation of the Wallbox cannot be guaranteed.
PLEASE NOTE!
In order to achieve the maximum charging output of the Wallbox, the power supply cable must be dimensioned and
installed for 32 A. The maximum charge current (see “Setup and test modes” on page 15) must also be set to 32 A.

PLEASE NOTE!
Factory settings for the Mercedes-Benz Wallbox Home are for maximum charging currents of 16A (A0009067408 model
variant) and 32A (A0009067508 model variant). Should the charging current made available by your domestic power sup-
ply or the supply cable itself differ from these settings, the charge current settings must be adjusted accordingly inside the
Wallbox before you replace the electronic components cover and then take the Wallbox into operation. This is described in
detail in section “Setup and test modes” on page 15 and following.
Please note that the rated current indicated on the product label and configured in the firmware must under no circum-
stances be exceeded.
11.Replace the electronic components cover inside the housing base and
fix it into place with its M4 x 10 screw.
12.Hook the housing cover onto the upper edge of the housing base and
lock it using the housing cover key provided.
Note: Before you replace the housing cover, you must complete the pro-
cess of taking the Mercedes-Benz Wallbox Home into operation – please
read the following section for information on this topic.
Taking the Wallbox into operation
Aer mechanical and electrical installation, you must check the correct functioning of the Mercedes-Benz Wallbox Home for
operation and resolve any errors.
Proceed as follows to take the Mercedes-Benz Wallbox Home into operation:
1. Switch on the upstream MCB in your domestic power distribution.
2. Open the access flap 8in the internal electronic components cover and also switch on the internal RCCB (the Wallbox is
connected to the electricity grid).
When the Wallbox is connected to the electricity grid, it will initiate the start-up procedure: This includes a test of the internal
electronic components to ensure correct functioning.
The internal check routine is indicated by the LED display on the front of the Mercedes-Benz Wallbox Home as follows.
LED display Description
The LED flashes white once ...
... and then pulsates blue.
The vehicle can now be connected for charging. Initiating and terminating charging procedures is described in detail in the
quick start guide included, as well as in the comprehensive operating manual for the Mercedes-Benz Wallbox Home: You can
download the comprehensive operating manual at www.yourwallbox.de/downloads/Mercedes-Benz/Home/. Please also
refer to the operating manual of the vehicle to be charged at the Wallbox.
Aer the Mercedes-Benz Wallbox Home has been properly taken into operation, replace the housing cover and lock it into
place: This is described in step 12 above.

Mercedes-Benz Wallbox Home| Preparations, installation and taking into operation
PLEASE NOTE!
To finalize the process of taking the Wallbox into operation, the maximum charge current setting of the power supply must
be checked inside the Wallbox and adjusted if required using the coded rotary switch. In order to perform a final check
of the functioning of the Wallbox, the contactor of the Wallbox must be checked in test mode for correct functioning. Test
mode is described in the next section.
Setup and test modes
If no vehicle is available for taking the Wallbox into operation or for testing it, you can check the functioning of the Mercedes-
Benz Wallbox Home (contactor, CP and RCD tripping) using test mode. You can also alter the factory setting for the maximum
charging current of the Mercedes-Benz Wallbox Home in setup mode using the coded rotary switch if the charge current
made available by the domestic power supply differs from this preset value. However, the rated current indicated on the prod-
uct label must not be exceeded under any circumstances.
The electronic components module of the Mercedes-Benz Wall-
box Home provides access to the coded rotary switch, which is
factory preset to the 0position, through the opening on the le
hand side.
For test and setup mode, you can set the coded rotary switch
to one of the values indicated on the cover around the opening
using the VDE blade screwdriver (0.5 x 2.5mm). You can find an
explanation of these values in section “Settings for the coded
rotary switch” on page 17.
In order to adjust the settings using the coded rotary switch, you
must remove the housing cover and, depending on the working
step, remove or replace the electronic components cover (see
steps 5 and 6 described on page 11 in section “Mechanical
and electrical installation”).
DANGER!
After opening the electronic components cover, dangerous voltages may be present on the inside of the Wallbox as well as
on components you are able to touch. ALWAYS switch off the MCB in the domestic power supply and the internal RCCB of
the Wallbox before you continue in setup or test mode.
Always observe the 5 golden rules of electrical installation:
1. Cut off all voltage sources
2. Secure all cut-off devices
3. Verify absence of voltage
4. Ground and short-circuit
5. Cover or bar access to adjacent components under voltage
Otherwise, there is a risk of severe or even fatal injury through electric shock!
Test mode
Proceed as follows to check the functioning of the Mercedes-Benz Wallbox Home in test mode:
