WARNING!
Allocation of wire colours
Please note that the colour-coding convention used above is not internationally standardised.
WARNING!
Checking the connection
Please ensure that the conductors that are pre-fixed to the RCCB terminals remain attached correctly after con-
necting the power supply cable.
DANGER!
Dangerous electrical currents
The electronic components of your wallbox will be damaged if a voltage above 250 V is applied between the L1
current-carrying conductor and neutral!
Data cable connections
In group installations, a Controller wallbox can control up to 15 Extender charge points after connecting up the data
cables. The Controller wallbox then centrally manages backend communication, charge current distribution, and many
other functions.
For wiring up, the internal bus interfaces of the Controller and Extender variants must be connected serially using
suitable data cables (see "Data cable recommendations" on page 60).
Inserting the data cables is described in
Step 10
in section "Electrical connection of the wallbox" on page 17.
The data bus interfaces are manufactured either as spring terminals (until mid-2021) or established via the RJ45
ports of the Easy2Install interface (called E2I in the following, from mid-2021).
