NOTE
Explanation of calibration law compliance
Calibration law compliance means that sets of measurement data for each charging procedure are saved perma-
nently. According to the legal regulations applicable in Germany, the electric energy consumed at public charging
stations must be billed in compliance with calibration law.
NOTE
Labelling for calibration law compliant products
To indicate calibration law compliance, the product category of calibration law compliant charging stations is ex-
tended by a 'plus' symbol.
Calibration law compliant Controller charging station: Controller +

Installation – Installation site requirements | 13
Installation
It is recommended to have the entire installation of the wallbox carried out by a qualified specialist electrical con-
tractor.
DANGER!
Dangerous electrical currents
Electrical installation, as well as final testing and certification for operation must be carried out by a qualified
specialist electrical contractor, who, on the basis of their specialist training and experience, as well as their
knowledge of the relevant standards, is able to assess and carry out the working steps described in this manual
and recognise potential hazards.
NOTE
Identical installation for Single and Twin variants
The Wallbox eMH3 is available as a Single (one charge point) or Twin (two charge points) variant. In principle, in-
stallation and commissioning are identical. However, the working steps described may need to be applied to both
charge points.
Installation site requirements
Your wallbox is suitable for outdoor use. Please note, however, that the permissible ambient conditions (see "Technical
specifications" on page55) must be adhered to in order to guarantee the functionality of your wallbox at all times.
The installation site must be freely accessible.
The mounting surface must be level and solid.
The mounting surface must measure at least 492×400mm
(height x width).
400 mm
492 mm
The installation height should be between 120 and 140cm
(ground to bottom edge of housing).
120 ~ 140 cm

| Installation – Tools and accessories required
14
Minimum distances to other technical installations must be
observed.
A minimum distance of 50cm is recommended.
Ideally, the installation site should provide a ready connection
to the electricity grid. Otherwise, a separate power supply
cable must be installed.
In order to operate group installations, suitable data cables
must also be installed in the installation site (see also "Prepar-
ing and fixing the wallbox in place" on page17 as well as
"Data cable connections" on page19).
Tools and accessories required
For mechanical installation, you will need the following components included with the wallbox:
Mounting plate, 1pc TX40 wafer head screws,
8×60mm, 4pcs
Wall plugs 10×50mm, 4pcs Triangular key, 1pc

In addition, you will need the following tools:
Electric drill Bit (Torx T20)
10 mm ∅drill bit suitable
for the respective mounting
surface
Pencil
Spirit level Tape measure

Pliers Utility knife
Wire stripper Multi-purpose installation
tester
Vehicle simulation adapter N PE
L1 L2 L3 Voltage tester
Preparing the installation site
As a matter of principle, the electrical supply cable in the domestic power distribution must be switched off for the
entire duration of mechanical and electrical installation. The connection to the power grid must only be made live for
the purpose of commissioning, after electrical installation is complete.
DANGER!
Dangerous electrical currents
Always observe the 5 safety rules:
1Cut power source
2Secure all cut-off devices
3Verify absence of voltage
4Ground and short-circuit
5Cover or bar access to adjacent components under voltage
Proceed as follows:
1 Using the spirit level, align the mounting plate level
and plumb on the mounting surface.
2 With the pencil, mark the fixing points in the
mounting position.

| Installation – Preparing the installation site
16
3 Pre-drill the marked fixing points with the electric
drill and drill bit (∅10 mm).
4 Drive the wall plugs into the fixing points with the
hammer.
5 Prepare the mounting plate for the insertion of the
power supply cable (red) and data cables (blue, if
required).
yInsertion from the top: Insert the cables
through the upper opening into the connection
area of the mounting plate and secure the supply
cables using the strain reliefs supplied (power:
large strain relief; data cables: small strain
reliefs).
yInsertion from the back: Drill through the
pre-stamped inlets in the connection area and
insert the cables. In this case you do not need
strain reliefs.
6 Insert the cables through the mounting plate and fix
the mounting plate to the four fixing points using
the four TX40 wafer head screws included.
7 Use a screwdriver or the electric drill with a suita-
ble bit.

WARNING!
Allocation of wire colours
Please note that the colour-coding convention used above is not internationally standardised.
WARNING!
Checking the connection
Please ensure that the conductors that are pre-fixed to the RCCB terminals remain attached correctly after con-
necting the power supply cable.
DANGER!
Dangerous electrical currents
The electronic components of your wallbox will be damaged if a voltage above 250V is applied between the L1
current-carrying conductor and neutral!
Data cable connections
In group installations, a Controller wallbox can control up to 15 Extender charge points after connecting up the data
cables. The Controller wallbox then centrally manages backend communication, charge current distribution, and many
other functions.
For wiring up, the internal bus interfaces of the Controller and Extender variants must be connected serially using
suitable data cables (see "Data cable recommendations" on page60).
Inserting the data cables is described in Step 10 in section "Electrical connection of the wallbox" on page17.
The data bus interfaces are manufactured either as spring terminals (until mid-2021) or established via the RJ45
ports of the Easy2Install interface (called E2I in the following, from mid-2021).

NOTE
Data bus system compatibility
The Wallbox eMH3 bus interfaces are completely downstream compatible. Wiring up spring terminals as well
as E2I interfaces in mixed group installations is possible at any time, as long as the correct terminal allocation is
kept consistent between the two systems. This allocation scheme is illustrated in section "Allocation schematic
from spring terminal to Easy2Install interface" on page61.
WARNING!
Mixed installation of ABL charging stations
Thanks to the common bus formats and interfaces, it is possible to connect up and operate charging stations
from different product series with each other and with the control units 1V0001/2. Configuration/connecting up
follows the schematic as described in the following.
However, please note that connecting up and operating calibration law compliant together with non-calibra-
tion law compliant charging stations in the same group is not possible!
Proceed as follows to connect the wallboxes via the E2I interfaces:
1 Connect the RJ45 plug of the first data cable to one
of the E2I interfaces inside the housing cover of the
Controller wallbox.
