Fronius Smart Meter TS 5kA-3
Device descrip-
tion
The Fronius Smart Meter TS is a bidirectional electricity meter which optimises self-con-
sumption 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 informa-
tion 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 equip-
ment.
▶Switch off the power supply before establishing a mains connection.
▶Observe the safety instructions.

To comply with European Directive 2012/19/EU on Waste Electrical and Elec-
tronic Equipment and its implementation as national law, electrical equipment
that has reached the end of its life must be collected separately and returned
to an approved recycling facility. Any device that you no longer require must be
returned to your distributor or disposed of at an approved collection and recyc-
ling facility in your area. Ignoring this European Directive may have potentially
adverse effects on the environment and your health!

Intended use The Fronius Smart Meter TS is a fixed piece of equipment for public grids of TN/TT sys-
tems 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 installa-
12

tion 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 cur-
rent 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, reg-
ulations, 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 access-
ible 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 reg-
ulations 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.

Positioning at consumption point:
For use as a secondary meter to measure individual loads and producers, see chapter
Multi-meter system on page 26.
Measuring accur-
acy
The Fronius Smart Meter TS has accuracy class 1 when measuring active energy (EN
IEC 62053-21) in the voltage ranges 400 - 480 VLL or 230 -277 VLN. Within the voltage
ranges 173 - 400 VLL or 100 - 230 VLN the accuracy class is 2 (active energy according
to EN IEC 62053-21, reactive energy according to EN IEC 62053-23). For further details

Installation
Checklist for
installation
For installation information, see the following chapters:
1Switch off the power supply before establishing a mains connection.
2Mount the Fronius Smart Meter TS (see Installation on page 18).
3Connect automatic circuit breakers or automatic circuit breakers and disconnectors
(see Protective circuit on page 18).
4Connect the mains cable to the Fronius Smart Meter TS (see Cabling on page 19).
5Mount the current transformers on the conductors. Make sure that the current trans-
formers are pointing in the correct direction. An arrow either points to the load or the
source (public grid) (see Connecting the current transformers on page 22).
6Connect the current transformer and Fronius Smart Meter TS (see Connecting the
current transformers on page 22).
7Make sure that the current transformer phases match the mains voltage phases (see
Connecting the current transformers on page 22).
8Note down the nominal current of the current transformer for each meter. These val-
ues will be required during setup.
9Connect the data communication connections of the Fronius Smart Meter TS to the
Fronius system monitoring (see Connecting the data communication cable to
the inverter on page 22).
10 If necessary, set terminating resistors (see Connecting the terminating resistor on
page 24).
11 Tug on each wire and plug to make sure that they are securely connected to the ter-
minal blocks.
12 Switch on the power supply to the Fronius Smart Meter TS.
13 Check the firmware version of the Fronius system monitoring. To ensure compatibil-
ity between the inverter and the Fronius Smart Meter TS, the software must always
be kept up to date. The update can be started via the inverter web page or using
Solar.web.
14 Set the transformation ratio of the current and voltage transformers (see Setting the
transformation ratio of the current and voltage transformers on page 29).
15 If several Fronius Smart Meter TS are installed in the system, set the address (see
"Setting the address" under Setting the address on the Fronius Smart Meter TS
on page 30).
16 Configure and commission the meter (see Start-up on page 31).

Installation The Fronius Smart Meter TS can be
mounted on a 35 mm DIN rail. The hous-
ing comprises 3 modules according to DIN
43880.
Protective circuit 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 discon-
necting 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.
- To monitor more than one mains voltage, use connected‑automatic circuit breakers.
- The overcurrent‑protection must protect the mains terminals with the designations
L1, L2 and L3. In rare cases, the neutral conductor has an overcurrent‑protection,
which must interrupt both neutral and non-earthed cables concurrently.
Auxiliary power
supply cabling
IMPORTANT!
An auxiliary power supply is required to operate the Fronius Smart Meter TS. The fuse
(F) must comply with the national standards and guidelines as well as the dimensions of
the conductors.
18

Cabling 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 - 4 mm²
- Recommended torque: max. 0.6 Nm
The measuring inputs of the current transformers must be earthed on one side as shown
in the circuit diagram.
Connect each voltage cable to the terminal strip as shown in the graphics below.
