| Installation of the Wallbox eM4 Twin
34
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.
Attach the supplied folding ferrite to a cable loop of the data cable. 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 provide the possibility of remote disconnection
by the local energy supplier. The Wallbox eM4 Twin offers a spring terminal 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 accord-
ance with VDE AR-N 4100" on page 19).
The following requirements apply to the control cable:
Solid conductor, 0.5 to 1.5 mm², stripping length: 9 mm
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 Twin:
1
Open the communication module to the front.
EXT.
CONTROL
2
Connect the control cable inserted via the
EXT. CON-
TROL
grommet to the terminal
EN1
.
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
ABL Configuration App
. To do this, please refer to the sections starting on page 42.
Preparing and installing the LTE USB stick
The Controller variants of the Wallbox eM4 Twin are supplied with an LTE USB stick for wireless communication with
a backend. The SIM card is provided by the backend provider and must first be inserted in the LTE USB stick. Then
plug the LTE USB stick into the USB interface of the Controller and set up the communication via the
ABL Configura-
tion App
(see page 43 onwards).
NOTE
Pre-configuration of the reev ready variants
In the reev ready variants, the LTE USB stick including the SIM card is plugged into the Controller wallbox ex
works and is pre-configured for communication with the reev dashboard.
