4.2 Provisions for flawless ISO 15118 communication
Installation recommendations when using more than one PLC Wallboxes.
PLC blocking filters:
If the vehicles are using ISO 15118 without SLAC mechanism (automatic pairing function), it is recommend-
ed to install PLC blocking filters in the supply line of the PLC Wallboxes. This avoids communication trouble
when charging two vehicles at the same time.
Suitable PLC blocking filters can be ordered from KEBA.
Network Membership Key’s (NMKs)
If the NMKs of the vehicles are different, PLC blocking filters are not required!
The NMK of a vehicle can be changed with the “KEBA - EV Connection Assistant” software that
can be downloaded from www.kecontact.com.

Additional information
With Public NMKs you are able to connect to devices in the whole network supported with PLC modems in
the Wallboxes. Private NMKs are useful to connect to one device specified in the network.
