The Product Type identifies product variations that may affect interoperability, such as communication protocols, configuration (e.g., phase count), or interface options. These differences must be explicitly stated in the Product Type to ensure transparency, particularly as communication technologies evolve (for example, NB-IoT versus LTE-M),
The Product Type may include:
• Configuration variants that directly affect certification (e.g., 1-phase vs. 3-phase).
• Communication technologies or protocols used (e.g., G3-PLC, GPRS/UMTS/LTE).
• Distinct firmware variants, where 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
