In case the P1 interface from the smart meter is used, mostly in the Netherlands and Belgium, the cable between the Smart Meter and P1-port on the Alfen charging station may not be longer than 20 meters.

The use of P1-splitters, longer cables, low-quality or damaged cables will cause no or interrupted communication and therefor correct operation of the Active Loadbalancing feature in the charger is not guaranteed.

The use of a shielded ethernet (UTP) cable, with twisted wires, is highly recommended.

When the distance between the meter and charger is longer than 20 meters, P1 must not be used.
Alternatively a Modbus TCP/IP meter (such as a Socomec) or Modbus RTU meter (RS-485, only available on some more recent models) should be considered.
Please refer to the external energy meter manual for more detailed information.
