NOTE
Continuation of the wiring diagram
Connect all wallboxes in the charging group via their LAN interfaces. To bring together all wallboxes, they must be connected
centrally to a router or switch in the local network infrastructure.

For interference suppression in the low-frequency range, you must attach the supplied folding ferrite to a cable loop in the data
line. It is recommended that you lay the cable loop outside the housing and lay it on the rear of the wallbox during installation.

If the wallbox is already installed, you can also connect the cable loop with the folding ferrite inside the wallbox.
Connecting a control cable in accordance with VDE AR-N 4100
According to the Application Rule VDE AR-N 4100, a wallbox must offer the possibility of remote disconnection by the local energy
supplier. The Wallbox eM4 Single offers a contact for this purpose, which is located in the right-hand area of the main module behind
the communication module (see also “External load shedding in accordance with VDE AR-N 4100” on page 18).
The following requirements apply to the control cable:
x
Solid conductor, 0.5 to 1.5 mm², stripping length: 9 mm
x
Fine-stranded conductor, 0.5 to 1.5 mm² / 0.5 to 1.0 mm² with ferrules, stripping length: 9 mm
Proceed as follows to connect the control cable to the Wallbox eM4 Single:
1
Open the communication module to the front.

3
Fold the communication module back up so that it clicks into
place.
After establishing the electrical connection of the control cable, the remote disconnection function must be activated via the
