4 Hardware installation
4.1 Common power line
The Wallboxes must be connected to one common power line with protective devices, otherwise the KeCon-
tact M10 is not able to perform a correct load management according to the maximum available current.
A clustering of Wallboxes is not permitted!
Be aware that each wallbox has to be secured by an individual RCD. Please see the “KeContact
P20 Installation manual” for further details about installation.
