NOTE
Compatibility with backend providers
The Wallbox eM4 Twin is available as a reev ready product, which is specially prepared for operation with the
backend solutions from reev. For more information, please visit:
Alternatively, the Wallbox eM4 Twin is also compatible with other backends for managing the charging infra-
structure. To check the compatibility, please contact the desired backend provider.
External load shedding in accordance with VDE AR-N 4100
The terminal
EN1
installed on the main module is used to connect a control control cable in accordance with
VDE AR-N 4100. The local energy supplier can use this control cable to remotely switch the charging function of the
wallbox off or on. The cable length between the wallbox and a suitable ripple control receiver / VDE-FNN control box
must not exceed 30 metres.
In addition to switching the two charge points on and off, there is also the option to limit the maximum current set for
charging via two further, externally wired resistor values.

* If the resulting charging current falls below the limit of 6 A, no charging occurs!
In a charging group, the control cable is connected to the Controller, which then regulates the current for all charge
points in the group. In all other configurations (charging group with external control unit, stand-alone), the control ca-
ble must be connected to the wallbox with the first charge point (assignment in line 2 of the energy meter:
).
