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.
▶
Observe the safety instructions.
▶
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 display the CE mark.
Regulatory Compliance Mark (RCM)
Complies with all applicable regulatory requirements in Australia and
New Zealand 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 installation information, see the following chapters:
Switch off the power supply before establishing a mains connection.
1
Mount the Fronius Smart Meter (see Mounting 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).
Connect the output terminals of the Fronius Smart Meter to the Fronius in-
5
verter (see Connecting the data communication cable to the inverter on
page 9).
If necessary, set terminating resistors (see Terminating resistors on page
6
11).
Tug on each wire and plug to make sure that they are securely connected to
7
the terminal blocks.
Switch on the power supply to the Fronius Smart Meter.
8
Check the firmware version of the Fronius inverter. To ensure compatibility
9
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.
If several Fronius Smart Meters are installed in the system, set the address
10
(see "Setting the address" under Setting the address of the Fronius Smart
Meter on page 17).
Configure and commission the meter (see Start-up on page 21).
11
Mounting The Fronius Smart Meter can be mounted on a 35 mm DIN rail. The housing
comprises 2 modules according to DIN 43880
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 just 10-30 mA, so that the nominal capacity
of all switches, disconnectors, fuses and/or automatic circuit breakers is determined by the wire gauge, mains voltage and required breaking capacity.
Switches, disconnectors and circuit breakers must be within sight and loc-
-
ated as close as possible to the Fronius Smart Meter; they must also be easy
to use.
Use automatic circuit breakers that are rated for max. 63 A.
-
To monitor more than one mains voltage, use connected automatic circuit
-
breakers.
The automatic circuit breakers must protect the mains terminal, which is
-
marked L1. In rare cases where the neutral conductor has overcurrent protection, the overcurrent protection device must interrupt both neutral and
non-earthed cables concurrently.
The circuit protection/disconnecting device must satisfy the requirements of
-
IEC 60947-1 and IEC 60947-3, as well as all national and local regulations
for electrical systems.

IMPORTANT!
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+, D-
▶
and M1+, M1-).
If the output cables are close to the mains cabling, use wires or cables that
▶
are designed for 300 V to 600 V (never less than the operating voltage).
Use double-insulated or sheathed output cables when they are close to bare
▶
conductors.
Use shielded twisted pair cables to avoid faults.
▶
The outputs of the Fronius Smart Meter are electrically isolated from haz-
▶
ardous voltages.

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
