2. INSTALLING AND ACTIVATING A FRONIUS SMART METER
2.1 Schematics and wiring requirements
/ Wiring between Fronius Smart Meter and inverter should use a CAT5 or CAT6 cable.
Important: To be compliant with the AS3000 standards, it is recommended to have the CAT5/CAT6 cable
in a heat shrink tubing (probably 10mm) when it enters the switchboard part. Alternatively, use a 240V
rated CAT5/CAT6 cable (e.g. Clipsal CBUS cable).
Please note: Use a torque screw driver with a rating of 1.2 Nm – 1.4 Nm for the AC cable input terminals
(Lin, Lout and Neutral) and a torque rating of 0.5 Nm – 0.8 Nm for the RS485 terminals. Any torque rating
above the prescribed limits will damage the meter terminals and will not be covered under warranty.
/ Connection is a data line for Modbus RTU / RS485 using screw terminals on the meter.
/ Maximum distance: 300 m (980 feet)
/ Use a single core per terminal connection between Fronius Smart Meter and Datamanager 2.0. For D+ and D-
use the single cores from the same colour (e.g. D+ is orange/white, D- is orange)
Meter connection on the Datamanager 2.0
The meter needs to be connected to the Datamanager’s terminal block using terminals D+, D- and -.
