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

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 Installation 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).

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 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 10 - 30 mA. The nominal capacity of the dis-

connecting 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 simultaneously interrupt neutral and unearthed lines.

Cabling WARNING!

Danger from mains voltage.

An electric shock can be fatal.

▶Switch off the power supply before connecting the mains voltage inputs to

the Fronius Smart Meter.

IMPORTANT!

Do not install more than one cable per screw terminal. If necessary, use terminal

blocks. Rate fuse according to the cross-section of the line.
