18 Introduction to the Wallbox eM4Single
NOTE
Compatibility with backend providers
The Wallbox eM4Single is available as a reevready product, which is specially prepared for operation with the backend solutions
from reev. For more information, please visit:

x Alternatively, the Wallbox eM4Single is also compatible with other backends for managing the charging infrastructure. To
check the compatibility, please contact the desired backend provider.
External load shedding in accordance with VDEAR-N4100
The terminal EN1 installed on the main module is used to connect a control control cable in accordance with VDEAR-N4100. The local
energy supplier can use this control cable to remotely switch the charging function of the wallbox o or on. The cable length between
the wallbox and a suitable ripple control receiver/ VDE-FNN control box has been tested up to a maximum of 30 metres.
In addition to switching the two charge points on and o, there is also the option to limit the maximum current set for charging via two
further, externally wired resistor values.
Position Resistance ±10%
Maximum set
current limited to
Resulting charging current
(e.g.: 32A/ 16A)
1 min. 27 kOhm 0% 0A/ 0A
2 4.7 kOhm 30% 9A/ 5A*
3 1.5 kOhm 60% 19A/ 10A
4 max. 100 Ohm 100% 32A/ 16A
* If the resulting charging current falls below the limit of 6A, 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 (multi-group, stand-alone), the control cable must be connected to the wallbox with the first charge point
(assignment in line 2 of the energy meter: ).
