Introduction to the Energy Management System home
The eMShome is recommended as a dynamic energy and load man-
agement system for use in private households. The fully integrated
three-phase smart meter measures the current energy consumption at
the grid connection point and allows the charging current to be dy-
namically adjusted and distributed in individual and group installations
with up to six eMH1 Wallboxes. This helps to avoid overloading the
house connection. PV surplus charging is possible thanks to surplus
metering. The eMShome web interface can be accessed via LAN for
configuration and monitoring purposes. This can display the charging
status and the current load on the individual phases in a conventional
browser.

The end user must be able to isolate the eMShome from the power supply by means of a freely accessible meter
fuse or an additional circuit-breaker.
WARNING!
Note on the correct assignment of the phases
Make sure that the phases are each assigned correctly. Otherwise, the eMShome will provide incorrect meas-
ured values.
Bus wiring of the wallboxes and the eMShome
To control the charging currents, all wallboxes in the system must be wired via a data cable and each set up via the
ABL Configuration Software (see “Configuration via the ABL Configuration Software” onpage17 onwards).
Communication between the eMShome and the eMH1 Wallboxes is via CAT5e or
equivalent data lines, which must comply with the specifications in section “Data
cable recommendations” onpage49.
The data lines are connected to the internal spring terminals (for products manu-
factured before mid-2021) or via the E2I interface (for products manufactured from
mid-2021) on the inside left of the eMH1 housing (see next section).
The data lines are fed in and out via the designated opening 1in the rear shell of
the housing (see installation instructions for the eMH1 Wallbox).
The total length of the data lines within the group installation must not exceed
100m.
WARNING!
Important note on plugging in the RS485 connector in the eMShome
Please note that the RS485 connector may only be plugged into the eMShome after configuration in the ABL
Configuration Software (see page17 onwards): Otherwise, there may be problems with communication in
the system.
Bus wiring via spring terminals
For bus wiring via spring terminals (for products manufactured before mid-2021), the following generally applies:
The twisted wires of the data line must be connected to the contacts evcc/rfid A and evcc/rfid B of the wall-
boxes’ internal spring terminals.
1

| System installation – Bus wiring of the wallboxes and the eMShome
14
The colour assignment between the data lines and the contacts evcc/rfid A, evcc/rfid B and evcc/rfid M
on the spring terminals must be identical in every wallbox in the system and must not be changed under any
circumstances.
The data line from the previous wallbox is connected to the left spring terminal, and the data line for the follow-
ing wallbox is connected to the right spring terminal.
Connect the data line to the RS485 connector of the eMShome in such a way that it is assigned to the spring
terminal in the first wallbox as follows (see also “PIN allocation within the system” onpage49):
RS485 terminal (eMShome) eMH1 spring terminal
Pin 3 Pin A
Pin 4 Pin B
Pin 2 Pin M
Bus wiring via E2I interface
For bus wiring via the E2I interfaces (for products manufactured from mid-2021), the following generally applies:
The data line is connected to the internal interfaces in the wallboxes via RJ45 connectors.
For pre-assembled cables with RJ45 connectors, the colour assignment within the data lines is already prede-
fined. In this case, the assignment to the RS485 terminal of the eMShome must be adapted in accordance with
the assignment below.
If you would like to assemble the data cables yourself, you should also use the following assignment as a guide
(see also “PIN allocation within the system” onpage49):

Starting the eMShome web interface
The eMShome is set up via a web interface that is optimised for the current version of the following web browsers:
Google Chrome
Mozilla Firefox
Apple Safari
Microsoft Edge
It is recommended that you use one of the web browsers mentioned above to ensure a problem-free configuration via
the web interface.
NOTE
Limited browser support
Please note that the Microsoft Internet Explorer web browser is not supported.
Log in to the eMShome
►Enter the IP address of the eMShome in the address bar of the web browser to open the login window.
If a DHCP server is active in the network, you can check in the configuration interface of the DHCP server which
IP address has been assigned to the MAC address of the eMShome. You will find the MAC address on the rating
plate attached to the side of the eMShome as well as on the rating plate included separately in the package (see
section on page7). A DHCP server is integrated as standard in many common router models.
NOTE
Automatic detection in home and workplace networks
On Windows computers, the UPnP service automatically detects the eMShome on the same network and dis-
plays it in the network environment. This allows users to find the unit on the network even if they do not know
the IPaddress. To be able to do this, your local network must be set to ‘Home network’ or ‘Work network’ but not
to ‘Public network’.
