Quick Installation Guide Energy profiling
(Fronius Smart Meter 50kA-3 / 63A-1 / 63A-3)

1.) AC wirning of Fronius smart meter

2.) Serial connecton of Modbus RTU cables
Example with Datamanager and four Fronius smart meter:

3.) Connect terminating resistor to the first Modbus device
As far as a Fronius smart meter is the first or last Modbus component, the enclosed terminating resistor has

to be connected to the data line.
