The Fronius Smart Meter is a bidirectional electricity meter for optimizing self-consumption and recording a household's load characteristic curve. Together with a Fronius inverter or Fronius Datamanager 2.0 and a Fronius data interface, the Fronius Smart Meter allows you to view your own power consumption. The meter measures the energy flow to the loads or to the public grid and forwards the information to the Fronius inverter or Fronius Datamanager 2.0 via the Modbus RTU/RS485 interface.

CAUTION!

Danger due to non-compliance with the safety instructions

Risk of injury and damage to the device as a result.

Follow all safety instructions.

Switch off the power supply before establishing the mains connection.

CAUTION!

Danger due to non-compliance with the safety instructions

Risk of injury and damage to the device as a result.

Follow all safety instructions.

Switch off the power supply before establishing the mains connection.

Technical data, labels, and safety symbols are located on the Fronius Smart Meter. They must not be removed or painted over. They warn against incorrect operation, as this may result in serious injury and property damage.

Symbols on the rating plate:
	CE label The equipment complies with all the requisite and relevant standards and directives that form part of the relevant EU directive, and therefore is permitted to display the CE label.
	RCM (Regulatory Compliance Mark) All relevant regulatory requirements in Australia and New Zealand are complied with in terms of safety and electromagnetic compatibility, as well as special requirements for radio equipment.
	WEEE label To comply with European Directive 2012/19/EU on Waste Electrical and Electronic Equipment and its implementation as national law, electrical equipment that has reached the end of its life must be collected separately and returned to an approved recycling facility. Any device that you no longer require must be returned to your distributor, or you must locate the approved collection and recycling facilities in your area. Ignoring this European Directive may have potentially adverse effects on the environment and your health.

The Fronius Smart Meter can be installed at two possible locations in the system, at the feed-in point and at the consumption point.

The Fronius Smart Meter can be mounted on a 35 mm DIN rail. The housing comprises 4 DUs (division units, max. 72 mm).

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.

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 grid terminals marked L1, L2, and L3. In rare cases, the neutral conductor has an overcurrent protection which must simultaneously interrupt neutral and ungrounded lines.

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.

Current path connection cross-section:

Wire (rigid): min. 1 mm² / max. 16 mm²
Wire (flexible): min. 1 mm² / max. 10 mm²
Recommended torque: 1.2 Nm / max. 1.4 Nm

Data communication and neutral conductor connection cross-section:

Wire (rigid): min. 0.05 mm² / max. 4 mm²
Wire (flexible): min. 0.05 mm² / max. 2.5 mm²
Recommended torque: 0.5 Nm / max. 0.8 Nm

Connect each voltage cable to the terminal strip as shown in the graphic below.

NOTE!

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.

The maximum cable length between the Fronius inverter and Fronius Smart Meter is 300 meters.

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 grid 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 hazardous voltages.

	Inverter in the system z. e.g., Fronius Symo
	Meter - Fronius Smart Meter Terminating resistor R 120 Ohm is included in the scope of supply.
	Fronius or third-party device, connection via Modbus RTU e.g., Fronius Ohmpilot, battery, etc.
	Terminating resistor R 120 Ohm

Due to interference, the use of terminating resistors according to the following overview is recommended for flawless operation.

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

	Grid Supplies the loads in the system if insufficient power is being generated by the PV modules or supplied by the battery.
	Inverter in the system e.g. Fronius Primo, Fronius Symo, etc.
	Utility meter Measures the metering data relevant for the billing of electricity quantities (primarily the kilowatt hours of grid purchases and grid power feed). On the basis of the data relevant for billing, the electricity retailer invoices a grid purchase and the purchaser of the surplus pays for the grid power feed.
	Primary meter Records the load curve of the system and makes the measured data available for energy profiling in Fronius Solar.web. The primary meter also regulates the dynamic feed-in control.
	Secondary meter Records the load curve of individual loads and producers (e.g. washing machine, lights, television, heat pump, etc.) in the consumption branch and makes the measured data available for energy profiling in Fronius Solar.web.
	Modbus RTU, Third-party device e.g. Fronius Ohmpilot, battery, etc.

Modbus	1	0
	1	1
	1	2
	1	3

If several Fronius Smart Meters are installed, a separate address must be set for each one (see Setting the address of the Fronius Smart Meter on page (→)). The primary meter always receives the address 1. All other meters are numbered consecutively in the address range from 2 to 14. Different Fronius Smart Meter power categories can be used together.

IMPORTANT!
Use no more than 3 secondary meters in the system. To avoid interference, it is recommended to install the terminating resistors according to the chapter Terminating resistors on page (→).
