2 System overview
The KeContact M20 enables control of multiple charging stations. The con-
nection is established over the IT network (switch/router). This makes charg-
ing with an intelligent load management possible. In combination with an up-
stream electricity meter, the entire charging network can be controlled dy-
namically (Modbus TCP).
Only one connection to backend systems is necessary (via OCPP). The
master (KeContact M20) is equipped with different network interfaces for
these functions.

Cluster
In a cluster consisting of multiple charging stations, the available power re-
serves can be used optimally across the entire system. Up to 200 P30 c-se-
ries (number depending on variant) in max. 15 clusters can be connected
with each other.

The following chapters describe which network interfaces are provided and
how to set up a network.

2.1 Network interfaces
The KeContact M20 provides the following network interfaces (e.g. for con-
nection to an OCPP backend, etc.):
● LAN
● Mobile network (via external antenna & SIM card, 4G/LTE - SIM card re-
quired, M2M SIM card recommended).
Fig.2-3: Configuration overview
1 ... LAN 2 ... Mobile network via SIM
3 ... USB interface
Client charging stations (P30 c-series) can only be connected to the master
(KeContact M20) over LAN. The configuration is done via the web interface
of the master.
Information
WLAN stick (WLAN access point / WLAN hotspot)
● The connection of a WLAN stick to the KeContact M20 is fundamentally
possible, but not recommended. Use at your own risk. In case of prob-
lems, troubleshooting is not assisted by the manufacturer.
● The login data for the first login to the web interface can be taken from
the supplied configuration label as needed.
