    1. Installation

    Installation

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

    1. Installation

    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 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 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.
    1. Installation

    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. The measuring inputs of the current transformers must be earthed on one side as shown in the circuit diagram.

    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 graphics below.

    1. Installation

    Selection criteria for current transformers

    General
    Do not use current transformers with a voltage output.
    Current transformers are directional. If they are mounted backwards or with swapped wires, the measured power will be negative.

    Primary current
    Maximum current per phase. A current transformer with a primary current greater than the maximum expected current per phase should be selected. The closer the expected current is to this value, the more precise the measurement will be.

    Secondary current
    The current transformer must supply alternating current at a nominal current of 1 or 5 A. The nominal values for the current transformer are listed in the current transformer data sheet.

    Power
    The Fronius Smart Meter needs 0.3 VA to carry out its measurements. Losses also occur on the outgoing and return leads. The power of the current transformer must be greater than the sum total of the power of the Fronius Smart Meter and the leads. The higher the power, the better.

    0.6 VA

    2.2 VA

    Example
    The length of the outgoing and return lead (0.5 m each) between the Fronius Smart Meter and the current transformer is a total of 1 m and has a copper cable cross-section of 1.5 mm²; the line resistance is therefore 0.6 VA according to the table above. The self-consumption of the Fronius Smart Meter is 0.3 VA.
    Line resistance 0.6 VA + self-consumption 0.3 VA = 0.9 VA
    → A current transformer with a rating of 1 VA, 1.5 VA, 5 VA or higher is suitable here.

    Accuracy class
    Use Class 1 or better (Class 0.5, 0.2, etc.). Class 1 is equivalent to a deviation of ± 1% of the secondary current at maximum power.

    Mounting
    Rigid or hinged.
    "Rigid" is usually cheaper with better power and accuracy values. Hinged current transformers can be opened for attachment to the conductor. To prevent it being opened inadvertently, a plastic cable tie can be secured to the current transformer. Hinged current transformers can be installed in a system without interrupting the voltage.

    1. Installation

    Connecting the current transformers

    • Make sure that the current transformers match the voltage 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.
    • Make sure that the current transformers are pointing in the correct direction. Observe the data sheet for the current transformer.

    Attach the current transformers to the conductor to be measured and connect the current transformer cables to the Fronius Smart Meter. Always switch off the power supply before disconnecting live conductors.

    The current transformers are connected to connections 1 and 3; 4 and 6; 7 and 9. If necessary, excessively long cables can be shortened accordingly. Observe the sequence in which the phases are connected. Accurate power measurement is only ensured if the mains voltage phases match the current phases.

    1. Installation

    Suitable voltage transformers

    Suitable voltage transformers: Only voltage transformers with a voltage range from 210 to 440 V (phase - phase) may be used. The voltage transformers must be connected to terminals 2, 5, 8 and 11 at the point of direct voltage measurement.

    1. Installation

    Connecting the data communication cable to the inverter

    Fronius SnapINverter:
    Connect the data communication connections of the Fronius Smart Meter to the Fronius system monitoring in the inverter. Several Smart Meters can be installed in the system, see chapter Multi-meter system - Fronius SnapINverter on page (→).

    1Connect 35 to -.
    2Connect 34 to D-.
    3Connect 33 to D+.

    Fronius GEN24 inverter:
    Connect the data communication connections of the Fronius Smart Meter to the Modbus interface of the Fronius GEN24 inverter. Several Smart Meters can be installed in the system, see chapter Multi-meter system - Fronius GEN24 inverter on page (→).

    1Connect 35 to GND.
    2Connect 34 to M1-.
    3Connect 33 to M1+.

    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.

    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 hazardous voltages.
