Fronius Smart Meter TS 5kA-3
Device descrip-
tion
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 Froni-
us 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.

Intended use 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 sys-
tem. The Fronius Smart Meter TS is required for systems with a battery storage
12

system and/or a Fronius Ohmpilot installed for communication between the indi-
vidual components. The installation is carried out on an indoor DIN rail with cor-
responding 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 en-
closed 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 accord-
ance 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 stand-
ards that apply to the installation, electrical safety and use of the product. Froni-
us 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 war-
ranty 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 med-
ical 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 - Fronius SnapINverter on page 27.
Measuring ac-
curacy
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 see Technical data on page 44.

Installation
Checklist for in-
stallation
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 discon-
nectors (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 cur-
rent transformers are pointing in the correct direction. An arrow either points
to the load or the source (public grid) (see Connecting the current trans-
formers on page 22).
6Connect the current transformer and Fronius Smart Meter TS (see Connect-
ing 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 values 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 communica-
tion cable to the inverter on page 23).
10 If necessary, set terminating resistors (see Connecting the terminating res-
istor on page 24).
11 Tug on each wire and plug to make sure that they are securely connected to
the terminal 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
compatibility between the inverter and the Fronius Smart Meter TS, the soft-
ware must always be kept up to date. The update can be started via the in-
verter 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 34).
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 35).
16 Configure and commission the meter (see Start-up on page 37).

Installation The Fronius Smart Meter TS can be
mounted on a 35 mm DIN rail. The
housing comprises 3 modules accord-
ing to DIN 43880.
Protective cir-
cuit
The Fronius Smart Meter TS is a hard-wired device and requires a disconnecting
device (circuit breaker, switch or disconnector) and overcurrent‑protection (auto-
matic‑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.
-To monitor more than one mains voltage, use connected‑automatic circuit
breakers.
-The overcurrent‑protection must protect the mains terminals with the desig-
nations L1, L2 and L3. In rare cases, the neutral conductor has an overcur-
rent‑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.
