The Fronius Smart Meter TS can be mounted on a 35 mm DIN rail. The housing comprises 2 modules according to DIN 43880.

The Fronius Smart Meter TS is a hard-wired device and requires a disconnecting device (circuit breaker, switch or disconnector) and overcurrent protection (automatic circuit breaker).

The Fronius Smart Meter TS consumes 10 - 30 mA, the nominal capacity of the disconnecting devices and the overcurrent protection is determined by the wire thickness, the mains voltage, and the required breaking capacity.

Disconnecting devices must be mounted within sight and as close as possible to the Fronius Smart Meter TS; they must also be easy to use.
The disconnecting devices must satisfy the requirements of IEC 60947-1 and IEC 60947-3, as well as all national and local regulations for electrical systems.
Use overcurrent protection rated for max. 100 A.
To monitor more than one mains voltage, use connected automatic circuit breakers.
The overcurrent protection must protect the grid terminal marked L1. In rare cases, the neutral conductor has an overcurrent protection, which must interrupt both neutral and non-grounded cables concurrently.

IMPORTANT!
Always switch off the power supply before connecting the mains voltage inputs to the Fronius Smart Meter TS.

Recommended thickness of stranded mains voltage cables for the terminals of the measuring input and measuring output:

Wire: 1 - 25 mm²
Recommended torque: max. 2.8 Nm

Recommended thickness of stranded wires for data communication terminals:

Wire: min. 0.05 mm²
Recommended torque: max. 0.5 Nm

Connect each voltage cable to the terminal strip as shown in the graphics below.

WARNING!

Danger due to electrical voltage from missing or improperly fitted protective cover.

An electric shock can be fatal and/or cause serious damage to property.

Fit the protective cover immediately after installing the live cables.

Fit the protective cover properly and check that it is secure.

Connect the data communication connections of the Fronius Smart Meter TS to the Modbus interface of the Fronius inverter using a network cable (type CAT5 or higher).

Several Smart Meters can be installed in the system, see chapter Multi-meter system - Fronius SnapINverter on page (→).

To avoid interference, the terminating resistor must be used (see chapter Connecting the terminating resistor on page (→)).

IMPORTANT!

Further information for successful commissioning.
Observe the following information on connecting the data communication cable to the inverter.

Use network cables of type CAT5 or higher.
The maximum cable length between the Fronius inverter and Fronius Smart Meter is 300 meters.
Use a mutual twisted cable pair for corresponding data lines (D+/D-, M0+/M0-).
On Fronius GEN24 inverters, the M0 and M1 inputs can be selected for this purpose.
If the data lines are close to the mains cabling, use wires or cables that are designed for 300 to 600 V (never less than the operating voltage).
Use double-insulated or sheathed data lines when they are close to bare conductors.
Use shielded twisted pair cables to avoid faults.
Two wires can be installed in each terminal; the wires are twisted first, inserted into the terminal, and tightened.
Note: A loose wire can disable an entire area of the network.
The data communication connections of the Fronius Smart Meter TS are electrically isolated from hazardous voltages.
