General
Device description
Symbols on the
device
The Fronius Smart Meter is a bidirectional electricity meter which optimises selfconsumption and records the household's load curve. In conjunction with the
Fronius inverter, Fronius Datamanager and Fronius data interface, the Fronius
Smart Meter 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.
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.

Installation
Checklist for installation
For installation information, see the following chapters:
Switch off the power supply before establishing a mains connection.
1
Mount the Fronius Smart Meter (see Installation on page 8).
2
Connect automatic circuit breakers or automatic circuit breakers and discon-
3
nectors (see Protective circuit on page 8).
Connect the mains cable to the Fronius Smart Meter (see Cabling on page
4
9).
Mount the current transformers on the conductors. Make sure that the cur-
5
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 12).
Connect the current transformer and Fronius Smart Meter (see Connecting
6
the current transformers on page 12).
Make sure that the current transformer phases match the mains voltage
7
phases (see Connecting the current transformers on page 12).
Note down the nominal current of the current transformer for each meter.
8
These values will be required during setup.
Connect the output terminals of the Fronius Smart Meter to the Fronius in-
9
verter (see Connecting the data communication cable to the inverter on
page 13).
If necessary, set terminating resistors (see Terminating resistors on page
10
14).
Tug on each wire and plug to make sure that they are securely connected to
11
the terminal blocks.
Switch on the power supply to the Fronius Smart Meter.
12
Check the firmware version of the Fronius inverter. To ensure compatibility
13
between the inverter and the Fronius Smart Meter, the software must always
be kept up to date. The update can be started via the inverter web page or
using Solar.web.
Set the transformation ratio of the current and voltage transformers (see
14
Setting the transformation ratio of the current and voltage transformers on
the Fronius Smart Meter on page 16).
If several Fronius Smart Meters are installed in the system, set the address
15
(see "Setting the address" under Setting the address of the Fronius Smart
Meter on page 21).
Configure and commission the meter (see Start-up on page 25).
16
Installation The Fronius Smart Meter can be mounted on a 35 mm DIN rail. The housing
comprises 4 DUs (division units, max. 72 mm).
Protective circuit
The Fronius Smart Meter 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 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.
8
Disconnecting devices must be mounted within sight and as close as possible
-
to the Fronius Smart Meter; 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. 63 A.
-
To monitor more than one mains voltage, use connected automatic circuit
-
breakers.
The overcurrent protection must protect the mains terminals marked L1, L2
-
and L3. In rare cases, the neutral conductor has an overcurrent protection
which must simultaneously interrupt neutral and unearthed lines.

Selection criteria for current
transformers
General
Do not use current transformers with a voltage output.
Current transformers are directional. If they are mounted backwards or with
swapped wires, the measured power will be negative.
Primary current
Maximum current per phase. A current transformer with a primary current greater than the maximum expected current per phase should be selected. The closer
the expected current is to this value, the more precise the measurement will be.
Secondary current
The current transformer must supply alternating current at a nominal current of
1 or 5 A. The nominal values for the current transformer are listed in the current
transformer data sheet.
Power
The Fronius Smart Meter needs 0.3 VA to carry out its measurements. Losses
also occur on the outgoing and return leads. The power of the current transformer must be greater than the sum total of the power of the Fronius Smart
Meter and the leads. The higher the power, the better.
11
Line resistances at different cross-sections (copper wires)
Secondary cur-
rent
[A]
5 1.5 0.3 VA 0.6 VA 1.5 VA 2.9 VA 5.8 VA
5 2.5 0.2 VA 0.4VA0.9 VA 1.8 VA 3.6 VA
5 4 - - 0.6 VA 1.1 VA 2.2 VA
Example
The length of the outgoing and return lead (0.5 m each) between the Fronius
Smart Meter and the current transformer is a total of 1 m and has a copper cable
cross-section of 1.5 mm²; the line resistance is therefore 0.6 VA according to the
table above. The self-consumption of the Fronius Smart Meter is 0.3 VA.
Line resistance 0.6 VA + self-consumption 0.3 VA = 0.9 VA
→ A current transformer with a rating of 1 VA, 1.5 VA, 5 VA or higher is suitable
here.
Accuracy class
Use Class 1 or better (Class 0.5, 0.2, etc.). Class 1 is equivalent to a deviation of ±
1% of the secondary current at maximum power.
Mounting
Rigid or hinged.
"Rigid" is usually cheaper with better power and accuracy values. Hinged current
transformers can be opened for attachment to the conductor. To prevent it being
opened inadvertently, a plastic cable tie can be secured to the current transformer. Hinged current transformers can be installed in a system without interrupting the voltage.

Connecting the
current transformers
Suitable voltage
transformers
Make sure that the current transformers match the voltage phases.
-
Make sure that current transformer L1 measures the current on the same
phase that is monitored by voltage input L1. The same applies for phases L2
and L3.
Make sure that the current transformers are pointing in the correct direction.
-
Observe the data sheet for the current transformer.
Attach the current transformers to the conductor to be measured and connect
the current transformer cables to the Fronius Smart Meter. Always switch off the
power supply before disconnecting live conductors.
The current transformers are connected to connections 1 and 3; 4 and 6; 7 and 9.
If necessary, excessively long cables can be shortened accordingly. Observe the
sequence in which the phases are connected. Accurate power measurement is
only ensured if the mains voltage phases match the current phases.
Suitable voltage transformers: Only voltage transformers with a voltage range
from 210 to 440 V (phase - phase) may be used. The voltage transformers must
be connected to terminals 2, 5, 8 and 11 at the point of direct voltage measurement.
