15Configure the Fronius Smart Meter IP and put it into operation (see Start-up on page (→)).

The Fronius Smart Meter IP can be mounted on a 35 mm DIN rail. The housing comprises 3 modules according to DIN 43880.

The Fronius Smart Meter IP is a hard-wired device and requires a disconnecting device (automatic circuit breaker).

The Fronius Smart Meter IP consumes 30 mA, the nominal capacity of the disconnecting devices and the overcurrent protection is determined by the conductor cross-sections, the mains voltage and the required breaking capacity.

The disconnecting devices must be mounted in the same enclosure (e.g. switch cabinet) as the Fronius Smart Meter IP.
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.
To monitor multiple mains voltages, use connected automatic circuit breakers.

NOTE!

Disconnecting device for the mains terminals

The automatic circuit breaker must protect the mains terminals marked L1, L2 and L3. In rare cases, the neutral conductor has a disconnecting device, which must interrupt both neutral and non-earthed cables concurrently.

WARNING!

Danger from live mains voltage inputs

An electric shock can be fatal.

Switch off the power supply before connecting the mains voltage inputs.

Permissible conductor cross-section of AC terminals:

Wire: 1.5 - 4 mm²

Each live conductor must be connected to the AC terminals as shown in the figures below.

3 phases, 4 conductors (CT connection)

1 phase, 2 conductors (CT connection)

2 phases, 3 conductors (CT connection)

It is recommended to use Fronius CT current transformers (item numbers 41,0010,0104 / 41,0010,0105 / 41,0010,0232). To ensure smooth operation of the Fronius Smart Meter IP and accurate measurement results, all connected current transformers must meet these requirements:

The current transformer must generate 333 mV at nominal current. The nominal current of the current transformers is listed in the data sheet for the current transformer.
Do not use current transformers with 1 ampere or 5 ampere output current.
Observe the maximum input current according to the data sheets of the current transformers.
Do not use Rogowski coils for measurement purposes.
Hinged and rigid current transformers can be mounted. Rigid current transformers often have better power and accuracy values. Hinged current transformers have a split core and can be opened for mounting on the conductor and installed in a system without interrupting the voltage.

CAUTION!

Risk of electric shock due to unintentional opening of hinged current transformers

This can result in severe injury and damage to property.

Switch off the current when working on the current transformers.

Attach a plastic cable tie to the current transformer to prevent unintentional opening.

1Make sure that the current transformers match the live phases. Make sure that current transformer L1 measures the current on the same phase that is monitored by voltage input L1. The same applies for phases L2 and L3. This is the only way to display correct measured values.

2Make sure that the current transformers are pointing in the correct direction.

NOTE!

Observe direction information when installing the current transformers

Negative power values occur when the current transformers are connected incorrectly.

Observe the data sheet and the marking on the current transformer (arrow indicates the direction to the load or to the public grid)

Check the correct position of the black and white cable.

3Note down the nominal current of the current transformer for each meter. These values will be required for commissioning.

4Attach the current transformers to the conductor to be measured and connect the current transformer cables to the Fronius Smart Meter IP.

WARNING!

Danger from mains voltage

An electric shock can be fatal.

Switch off the power supply before disconnecting live conductors.

5Connect the current transformers to the terminals CT1 (white / black), CT2 and CT3. Excessively long cables can be shortened accordingly. Observe the sequence in which the phases are connected.

6Route the mains conductors through the current transformers (see Cabling).

NOTE!

Cable length of the current transformers

Cables that are too long can have a negative effect on the measuring accuracy.

If a cable extension is necessary, use a shielded 0.34 to 1.5 mm2 (AWG 22-16) CAT 5 STP (Shielded Twisted Pair) cable rated for 300 V or 600 V (higher than the operating voltage).

NOTE!

Unusual measured values on unused phases

If unusual measured values occur on unused phases, bypass the unused current transformer inputs.

To do so, for each unused current transformer, connect the terminal marked with a white dot to the terminal marked with a black dot using a short cable.

Observe the following instructions:

Use a shielded data cable of type CAT 5 STP (Shielded Twisted Pair) or higher.
If the data lines are close to the mains cabling, use cables that are designed for 300 to 600 V (never less than the operating voltage).
Use double-insulated or sheathed data cables when they are close to bare conductors.
The use of a static IP address is recommended.

IMPORTANT!
Ensure sufficient WLAN signal strength at the installation site. If the signal strength is low, a WLAN booster must be installed, for example.

The use of a static IP address is recommended.

Connect the data communication connections of the Fronius Smart Meter IP to the Modbus interface of the Fronius inverter using a CAT 5 STP (Shielded Twisted Pair) or higher data cable.

The Fronius Smart Meter IP can also be connected to the network (LAN / WLAN). This allows software updates to be carried out.

Standard Modbus address & TCP port:

Address: 1
TCP port: 502

To avoid interference, the terminating resistor must be used (see chapter Setting the Modbus RTU terminating resistor on page (→)).

If a battery is installed in the system, the BIAS switch must be set (see chapter Setting the Modbus RTU BIAS on page (→)).

Further settings are necessary on the user interface of the inverter and the Fronius Smart Meter IP (see Advanced settings).

IMPORTANT!
A loose wire can disable an entire area of the network. The data communication connections of the Fronius Smart Meter IP are electrically isolated from hazardous voltages.

Further information for commissioning
Observe the following information on connecting the data communication cable to the inverter.

Use a shielded CAT 5 STP (Shielded Twisted Pair) or higher data cable to avoid interference.
Use a mutual twisted cable pair for corresponding data lines (D+/D-, M1+/M1-).
If the data lines are laid close to the mains cabling, cables or wires that are designed for 300 to 600 V must be used (never less than the operating voltage).
Use double-insulated or sheathed data lines when they are close to bare conductors.
Two wires can be installed in each terminal; the wires are twisted first, inserted into the terminal and tightened.

	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 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 Records the load curve of individual producers (e.g. wind power plant) in the consumption branch and provides measurement data for energy profiling in Fronius Solar.web.
	Modbus RTU secondary device e.g. Fronius Ohmpilot, battery, etc.
	Loads in the system e.g. washing machine, lamps, TV, etc.

	Additional producers in the system e.g. wind power plant
	Terminating resistor R 120 Ohm

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

IMPORTANT!
Max. 7 secondary meters may be used in the system. A data connection via RTU as well as TCP is possible. To avoid interference, it is recommended to install the terminating resistors according to chapter Setting the Modbus RTU terminating resistor on page (→).

Location of the primary meter in the consumption branch. *Terminating resistor R 120 Ohm

Location of the primary meter at the feed-in point. *Terminating resistor R 120 Ohm

The following must be observed in a multi-meter system:

Connect the primary meter and the battery to different channels (recommended).
The remaining Modbus participants must be distributed evenly.
Only assign each Modbus address once.
Terminating resistors must be positioned individually for each channel.
