Terminating res-
istors - explana-
tion of symbols
Inverter in the system
e.g. Fronius Symo
Meter - Fronius Smart Meter
Terminating resistor is integrated in the meter.
Modbus RTU slave
e.g. Fronius Ohmpilot, Fronius Solar Battery, etc.
Termination resistance
R 120 Ohm
Terminating Res-
istors
The system might work without terminating resistors. Due to interferences, the use of ter-
minating resistors according to the following schemes are recommended.
Activate the Fronius Smart Meter terminat-
ing resistor (R 120 Ohm) by switching pin
7 to ON (1).
