| Installation – Preparing the mounting site
10
Preparing the mounting 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.
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 Cut crosswise into the marks for the fixing points
on the drilling template using the utility knife.
2 Using the spirit level, align the drilling template
level and plumb on the mounting surface.
3 With the pencil, mark the fixing points in the
mounting position.
4 Pre-drill the marked fixing points with the electric
drill and drill bit (∅8 mm).
5 Drive the wall plugs into the fixing points with the
hammer.

housing cover key and put it aside.
8 Loosen the screw of the internal electronic com-
ponents cover using the screwdriver (Torx) and put
it aside.
yKeep the screw in a safe place.
9 Use the utility knife to cut an opening for the
power supply cable into the large rubber grommet
in the housing base.
yFor wiring up group installations, you must also
make cuts into the two smaller grommets for
the data cables (see "Data cable connections"
on page 14).

| Installation – Electrical connection of the wallbox
12
10 Insert the power supply cable through the large
rubber grommet into the housing base.
yThe back of the housing has a cable guide for
surface-mounted power supply cables.
yFor wiring up group installations, you must
insert the data cables through the small grom-
mets in the housing base.
11 Hang the housing base onto the panhead screws
you inserted at the installation site in Step 6.
12 Fix the housing base to the mounting surface by
inserting the two remaining panhead screws into
the two lower fixing points using the screwdriver
or electric drill with Torx bit.
ySelect a torque that will not distort the housing
base.
Electrical connection of the wallbox
Electrical connection must be carried out by a qualified specialist electrical contractor!
Ensure that the power supply cable remains disconnected from the electricity grid.
Deactivate the RCCB in the wallbox and/or in the domestic power supply.

Installation – Electrical connection of the wallbox | 13
Proceed as follows to connect the power supply cable inside the wallbox:
1 Cut the supply cable to the required length with
the pliers.
yFor wiring up group installations (see next
section), you must also cut the data cables to
the required length.
2 Insert the individual conductors of the power
supply cable into the respective terminals of the
RCCB and tighten them using the screwdriver
(torque: 2.5 to 3 Nm).
yEnd ferrules must be fitted on flexible
conductors.
yOperate the spring-loaded mechanism of the
PE terminal and attach the protective earth
conductor.
yUse the connection patterns listed below to
allocate the individual conductors.
Connection pattern for 3-phase TN system
Designation Conductor color Marks for
Phase 1 current-carrying conductor Brown 5– L1
Phase 2 current-carrying conductor Black 3– L2
Phase 3 current-carrying conductor Gray 1– L3
Neutral Blue N
Protective earth Green-Yellow PE
Connection pattern for 1-phase TN system
Designation Conductor color Marks for
Phase 1 current-carrying conductor Brown 5– L1
Neutral Blue N
Protective earth Green-Yellow PE
Please note that the colour-coding convention used above is not internationally standardised.
Please ensure that the conductors that are pre-fixed to the RCCB terminals remain attached correctly
after connecting the power supply cable.
If desired, the 3-phase Wallbox eMH2 model variant can also be connected and operated on a single
phase at terminal 5– L1: However, in this case the rated output for the wallbox will not be achieved.
The electronic components of your wallbox will be damaged if a voltage above 250V is applied between
the 5– L1 current-carrying conductor and the neutral conductor!

| Installation – Data cable connections
14
Data cable connections
In group installations, a Master wallbox can control up to 15 Slave wallboxes after connecting the respective data
cables. The Master wallbox then centrally manages backend communication, charge current distribution and many
other functions.
To connect up a group installation, data cables must be attached to the internal spring terminals of the Wallbox
eMH2. You can find information regarding recommended data cables in section "Data cable recommendations" on
page 33.
Proceed as follows to connect the wallboxes using data cables:
1 Using the wire stripper, strip the data cables you
inserted into the housing base in Step 10 of Sec-
tion "Electrical connection of the wallbox".
yCut the data cables to the required length with
the pliers if necessary.
2 Connect the twisted wire strands of the first data
cable with the right hand spring terminal in the
Master wallbox and route the cable to the first
Slave wallbox.

Commissioning the wallbox
To commission the wallbox, the power supply cable must be connected to the electricity grid.
The following working steps must be carried out with the utmost care: There is a risk of electric shock if
conductive components are touched.
1 Switch on the MCB in the domestic power distri-
bution box.
yAs soon as the wallbox is connected to the
electricity grid, the green LED will begin to
pulsate, the other LEDs will remain OFF.
Should the LED not pulsate, check the RCCB and the MCB inside the Wallbox eMH2 and switch the pivot
levers to position Iif necessary.
2 Measure the voltage at the RCCB terminals.
yIn single phase installations, the voltage is
measured between the phase and neutral
conductors.
yIn 3-phase systems, all phases are measured
against each other (400 V) and all phases
are measured against the neutral conductor
(230V).

| Installation – Commissioning the wallbox

Now conduct all locally required checks and testing of the wallbox and its electrical installation. These
include the following tests:
Effectiveness of protective earth conductor connections
Insulation resistance
Loop impedance
Voltage drop
RCCB tripping current and tripping time
Rotating field testing
as well as additional tests according to local regulations.
3 Replace the electronic components cover onto the
housing base and fix it into place with the screw
you removed in Step 8 of Section "Preparing and
fixing the wallbox in place" on page 11.
4 Hook the housing cover onto the upper edge of
the housing base and lock it using the housing
cover key.
The installation of the Wallbox eMH2 is now complete and the wallbox is ready for operation.

Configuring the Wallbox eMH2 – Stand-alone operation of a Master wallbox | 17
Configuring the Wallbox eMH2
The Wallbox eMH2 is delivered preconfigured for operation as either a Master or Slave wallbox within a group instal-
lation. However, you can also operate the Wallbox eMH2 as a stand-alone charging station.
Stand-alone operation of a Master wallbox
The Master wallbox is delivered preconfigured for operation as a single charging station, but in this case without the
option of authorising charging procedures via RFID.
Should you wish to bar or allow the charging function via RFID registration, you must configure and operate the wall-
box using a suitable backend. ABL recommends the backend product by the provider reev, who is offering solutions
that are specifically tailored to the Wallbox eMH2.
For further information, please visit:
https://reev.com
Your Wallbox eMH2 can also be integrated into the charging infrastructure systems of other backend
providers.
You can obtain further information from the dealer where your purchased your wallbox.
Stand-alone operation of a Slave wallbox
In principle, Slave wallboxes are factory preconfigured to operate in combination with a Master wallbox.
However, with the ABL Configuration Software you can set up a Slave wallbox for stand-alone operation without
Master or backend. You can download the ABL Configuration Software free of charge in the Service > All down-
loads > Software section at www.ablmobility.de.
You will need the following separately available accessories to configure the wallbox for stand-alone operation:
Windows PC (laptop recommended) with at least one free USB port
Commercially available Type A to Type A USB extension cable
or
LOMK218 cable set (available as an optional accessory from ABL Sursum, see "Accessories" on page 7).
The following working steps must always be carried out by a qualified specialist electrical contractor!
Proceed as follows to configure a Slave wallbox for stand-alone operation:
1 Disconnect the Slave wallbox from the electricity
supply.
2 Open the housing cover of the wallbox with the
housing cover key and put it aside.
