General
Explanation of
safety notices DANGER!
Indicates immediate danger.
▶If not avoided, death or serious injury will result.
WARNING!
Indicates a potentially hazardous situation.
▶If not avoided, death or serious injury may result.
CAUTION!
Indicates a situation where damage or injury could occur.
▶If not avoided, minor injury and/or damage to property may result.
NOTE!
Indicates a risk of flawed results and possible damage to the equipment.
Description of the
device
The Fronius Smart Meter is a bidirectional electricity meter for optimising your own con-
sumption and recording the load curve of the household. Together with the Fronius
Datamanager, the Fronius Smart Meter provides a clear overview of your own electricity
consumption.
The meter measures the power flow to the loads or the grid and forwards the information
to the Fronius Datamanager via ModBus RTU/RS485 interface.
CAUTION!
Observe and follow the safety instructions!
Non-observance of the safety instructions will result in damage to persons and equip-
ment.
▶Switch off the power supply before making a grid connection.
▶Observe the safety instructions.
Symbols on the
device
Technical data, markings and safety symbols are located on the Fronius Smart Meter.
These must not be removed nor painted over. The notices and symbols warn of incorrect
operation that could result in serious injury and damage to property.
Symbols on the rating plate:
CE mark
The devices conform to all the requisite and relevant standards and guidelines
that form part of the relevant EU directive, and are therefore permitted to dis-
play the CE mark.
6

Regulatory Compliance Mark (RCM)
Complies with all applicable regulatory requirements in Australia and New Zea-
land regarding safety and electromagnetic compatibility, as well as specific
requirements for radio equipment.
WEEE mark
In accordance with European Directive 2012/19/EU on waste electrical and
electronic equipment and its implementation in national law, used electrical
devices must be collected separately and recycled in an environmentally
responsible manner. Ensure that you return your used device to your dealer or
obtain information regarding a local, authorised collection and disposal system.
Failure to comply with this EU Directive may result in a negative impact on the
environment and your health!
Positioning The Fronius Smart Meter can be installed at two possible locations in the system: at the
feed-in point and at the consumption point.

Installation
Checklist for
installation
For information about installation, please refer to the sections stated below
1Switch off the power supply before establishing a mains connection
2Mount the Fronius Smart Meter (see "Installation" on page 8)
3Connect automatic circuit breakers or automatic circuit breakers and disconnectors
(see"Protective circuit" on page 8)
4Connect the mains cable to the Fronius Smart Meter (see "Cabling" on page 8)
5Connect the output terminals of the Fronius Smart Meter to the Fronius system mon-
itoring using a suitable cable (see "Connecting the data communication cable to
the inverter" on page 9)
6If necessary, set terminating resistors (see "Terminating resistors" on page 10)
7Tug on each wire and plug to make sure that they are securely connected to the ter-
minal blocks.
8Switch on the power supply to the Fronius Smart Meter
9Check the firmware version of the Fronius system monitoring. To ensure compatibil-
ity between the inverter and Fronius Smart Meter, the software must always be kept
up-to-date. The update can be started via the inverter website or via Solar.web.
10 If several Fronius Smart Meters are installed in the system, set the address (see
"Setting the address" under "Setting the address of the Fronius Smart Meter" on
page 13)
11 Set the meter location via the Fronius system monitoring web interface under "Set-
tings - Meter - Settings" (see "Configuring the web interface" on page 14)
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 (cir-
cuit breaker, switch or disconnector) and overcurrent protection (automatic circuit
breaker).
The Fronius Smart Meter consumes 10 - 30 mA. The nominal capacity of the disconnect-
ing 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; 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 simul-
taneously interrupt neutral and unearthed lines.
Cabling IMPORTANT!
Always switch off the power supply before connecting the mains voltage lines to the
Fronius Smart Meter.

If several Fronius Smart Meters are being installed, see chapter "Multi-meter system"
on page "12".
ATTENTION! ?
More information on successful commissioning.
Note the following information about connecting the data communication cable to the
inverter.
▶Use cables of type CAT5 or higher.
▶Use a mutual twisted cable pair for data lines that belong together (D+ and D-).
▶If the output cables 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 output cables when they are close to bare con-
ductors.
▶Use shielded twisted pair cables to avoid faults.
▶The outputs of the Fronius Smart Meter are electrically isolated from hazardous
voltages.
Terminating res-
istors
Due to interference, it is recommended that terminating resistors are used as illustrated
below to ensure proper functioning.
10

* The terminating resistor on Fronius Smart Meters is installed between A and B. The
terminating resistor R 120 Ohm is included with the Fronius Smart Meter.

If several Fronius Smart Meters are being installed, a separate address (see Setting
the address of the Fronius Smart Meter page 13) must be set for each one. The
primary meter always has address 1, all other meters are numbered in the address
range from 2 to 14. Different types of Fronius Smart Meter can be used together.
