The Fronius Smart Meter TS is a bidirectional electricity meter which optimises self-consumption and records the household's load curve. In conjunction with the Fronius inverter, Fronius Datamanager and Fronius data interface, the Fronius Smart Meter TS provides a clear overview of a user's own power consumption.

The meter measures the power flow to the loads or to the grid and forwards the information via the Modbus RTU/RS485 communication to the Fronius inverter and the Fronius Datamanager.

CAUTION!

Observe and follow safety instructions!

Failure to observe the safety instructions will result in damage to personnel and equipment.

Switch off the power supply before establishing a mains connection.

Observe the safety instructions.

The Fronius Smart Meter TS is a fixed piece of equipment for public grids of TN/TT systems and records self-consumption and/or individual loads in the system. The Fronius Smart Meter TS is required for systems with a battery storage system and/or a Fronius Ohmpilot installed for communication between the individual components. The installation is carried out on an indoor DIN rail with corresponding back-up fuses, which are adapted to the cable cross-sections of the copper conductors and to the maximum current of the meter. The Fronius Smart Meter TS must only be operated in accordance with the specifications in the enclosed documentation and in accordance with local laws, regulations, provisions, standards and within the limits of technical possibilities. Any use of the product other than as described in the intended use shall be deemed to be not in accordance with the intended purpose. The available documentation forms part of the product and must be read, observed and kept in good condition. It must also be accessible at all times at the place of installation. The available documents do not replace regional, state, provincial or national laws, or regulations or standards that apply to the installation, electrical safety and use of the product. Fronius International GmbH assumes no responsibility for compliance with or non-compliance with these laws or regulations in connection with the installation of the product.

Interventions on the Fronius Smart Meter TS, e.g. modifications and alterations, are not permitted. Unauthorised interventions will void the warranty and warranty claims and, as a rule, void the user's authority to operate the equipment. The manufacturer shall not be liable for any damage resulting from such use.

Reasonably foreseeable misuse:
The Fronius Smart Meter TS is not suitable for the supply of life-sustaining medical devices or for the billing of subtenants.

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 mains terminals with the designations L1. In rare cases, the neutral conductor has an overcurrent‑protection, which must interrupt both neutral and non-earthed 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.

1 phase, 2 conductors

Insert the protective cover into the guide and press firmly.

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!

More information on successful commissioning.
Note the following information about connecting the data communication cable to the inverter.

Use network cables of type CAT5 or higher.
Use a mutual twisted cable pair for corresponding data lines (D+/D-, M1+/M1-).
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.

	Inverter in the system e. g. Fronius Symo
	Meter - Fronius Smart Meter TS Terminating resistor R 120 Ohm is set with a wire jumper between M- and T.
	Modbus RTU slave e. g. Fronius Ohmpilot, Fronius Solar Battery, etc.
	Terminating resistor R 120 Ohm

The terminating resistor is integrated in the Fronius Smart Meter TS and is manufactured with a bridge between the M and T connections (T = termination).

Due to interference, it is recommended that terminating resistors are used as illustrated below to ensure proper functioning.

Insert the connection covers into the guides and press firmly.

IMPORTANT!
When fitting the connection covers, ensure that the cables are not kinked, pinched, crushed or otherwise damaged.

	Grid supplies the loads in the system if insufficient power is being generated by the PV modules or supplied by the battery.
	Inverter in the system e. g. Fronius Primo, Fronius Symo, etc.
	Utility meter Measures the measurement data relevant for billing amounts of energy (in particular kilowatt hours of energy sourced from the grid and energy fed into the grid). Based on the relevant billing data, the electricity retailer will invoice the energy sourced from the grid and the purchaser of the surplus energy will reimburse the energy fed into the grid.
	Primary meter Records the system's load curve and provides measurement data for energy profiling in Fronius Solar.web. The primary meter also controls the dynamic feed-in control.
	Secondary meter Records the load curve of individual loads (e.g. washing machine, lamps, TV, heat pump, etc.) in the consumption branch and provides measurement data for energy profiling in Fronius Solar.web.
	Producer meter Records the load curve of individual producers (e.g. wind power plant) in the consumption branch and provides measurement data for energy profiling in Fronius Solar.web.
	Modbus RTU slave e. g. Fronius Ohmpilot, Fronius Solar Battery, etc.
	Loads in the system e. g. washing machine, lamps, TV, etc.
	Additional loads in the system e. g. heat pump

	Terminating resistor R 120 Ohm

A maximum of 4 Modbus participants can be connected to the Modbus terminal.

IMPORTANT!
Only one primary meter, one battery and one Ohmpilot can be connected per inverter. Due to the high data transfer of the battery, the battery occupies 2 participants.

Example:

Input	Quantity Primary meter	Quantity Secondary meter
Modbus	1	0
	1	1
	1	2
	1	3

If several Fronius Smart Meter TS are installed, a separate address must be set for each (see Setting the address on the Fronius Smart Meter TS on page (→)). The primary meter is always assigned address 1. All the other meters are numbered consecutively with the address range from 2 to 14. Different Fronius Smart Meter power categories can be used in combination.

IMPORTANT!
Max. Use 3 secondary meters in the system. To avoid interference, it is recommended to install the terminating resistors according to chapter Connecting the terminating resistor on page (→).
