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.
