Allocation schematic from spring terminal to Easy2Install interface
For mixed data cabling connections using E2I interfaces as well as spring terminals within one group installation, the
below allocation schematic must be followed. For each length of cable between these two interface systems, one un-
braided RJ45 to individual strand Ethernet/patch cable (1 pc) is required.
The following allocations are then made:
Controller/Extender with spring terminal to Extender with Easy2Install interface
In this configuration, the individual wire strands of an Ethernet cable (CAT5e or above), which has been unbraided
at one end, are connected to spring terminal
R
of the Controller or Extender charging station, while the RJ45 plug
of the Ethernet cable is inserted into the left hand side Easy2Install interface of the next Extender charging sta-
tion.
Controller/Extender with Easy2Install interface to Extender with spring terminal
In this configuration, the RJ45 plug of the Ethernet cable is inserted into the right hand side Easy2Install interface
of the Controller or Extender charging station, while the unbraided wire strands of the Ethernet cable are connect-
ed to spring terminal
L
of the next Extender charging station.
In both cases, the individual wire strands of the Ethernet cable must be allocated as illustrated below.

WARNING!
Identical allocation of wire strands
Please note:
As no standard exists for the allocation of wire strands colours to the contacts of an RJ45 plug, the above
illustration only shows the allocation of the RJ45 contact to the spring terminal contact.
These allocations must be followed consistently, otherwise faultless communication within the system is
impossible.
Data cabling via LOMK218
In case of all Wallboxes eMH2 with spring terminals (until mid-2021), you can, instead of the configuration kit CONF-
CAB, also use the cable kit LOMK218 for data cable connections to a computer.
However, the following limitations apply:
The LOMK218 can only be used in conjunction with the ABL Configuration Software up to version 1.6. From ver-
sion 1.7 and above, you must always use the configuration kit CONFCAB.
Using LOMK218, either the CONTROL or the METER bus of the wallbox can be accessed, but not both at the
same time. To set up the charge controller and the RFID module, the RS485 to RJ12 adapter from LOMK218 must
therefore be connected to terminals
A
,
M
and
B
for the
CONTROL
bus. To set up the energy meter or the logging
gateway (if present), you first need to disconnect the RS485 to RJ12 adapter, and then connect it to terminals
A
,
M
und
B
for the
METER
bus.
