The Product Type specifies variations that affect interoperability such as communication protocols, configuration (e.g., phase count), or interface options. As communication technologies evolve (for example, NB-IoT versus LTE-M), these differences should be explicitly stated in the Product Type to ensure transparency.


This includes:

• Configuration variants directly impacting certification (e.g., 1-phase vs. 3-phase).

• Communication technologies or protocols used (e.g., G3-PLC, GPRS/UMTS/LTE).

• Distinct firmware variants if applicable.

• Major functional differences (e.g., with or without disconnection switch).


Examples:

Single phase, G3-PLC and GPRS/UMTS/LTE Three phase, G3-PLC and LoRaWAN Single phase, WiFi only, no disconnector
