cordance with Part 15 of the FCC regulations. The limit values should provide adequate protection against harmful interference in homes. This device creates and uses high frequency energy and can interfere with radio communications when not used in accordance with the instructions. However, there is no guaran- tee against interference occurring in a particular installation. -
Page 7: General
Together with the Fronius inverter, the Fronius Datamanager and the Fronius data inter- face, the Fronius Smart Meter provides a clear overview of your own power con- sumption. The meter measures the power flow to the loads or to the grid and forwards the information to the Fronius inverter via ModBus RTU/RS485 communication. - Page 8 Positioning at the consumption point The positioning of the Fronius Smart Meter at the consumption point.
