General
Device descrip-
tion
The Fronius Smart Meter 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 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.
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 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 envir-
onmentally 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 in-
stallation
For installation information, see the following chapters:
1Switch off the power supply before establishing a mains connection.
2Mount the Fronius Smart Meter (see Mounting on page 8).
3Connect automatic circuit breakers or automatic circuit breakers and discon-
nectors (see Protective circuit on page 8).
4Connect the mains cable to the Fronius Smart Meter (see Cabling on page
9).
5Connect the output terminals of the Fronius Smart Meter to the Fronius in-
verter (see Connecting the data communication cable to the inverter on
page 9).
6If necessary, set terminating resistors (see Terminating resistors on page
11).
7Tug on each wire and plug to make sure that they are securely connected to
the terminal blocks.
8Switch on the power supply to the Fronius Smart Meter.
9Check the firmware version of the Fronius inverter. To ensure compatibility
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.
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 17).
11 Configure and commission the meter (see Start-up on page 21).
Mounting The Fronius Smart Meter can be mounted on a 35 mm DIN rail. The housing
comprises 2 modules according to DIN 43880
Protective cir-
cuit
The Fronius Smart Meter 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 consumes just 10-30 mA, so that the nominal capacity
of all switches, disconnectors, fuses and/or automatic circuit breakers is determ-
ined 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 pro-
tection, 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.

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.
