    Installation

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

    Protective circuit

    The Fronius Smart Meter TS 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 TS 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 TS; 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.
    • To monitor more than one mains voltage, use connected‑automatic circuit breakers.
    • The overcurrent‑protection must protect the mains terminals with the designations L1, L2 and L3. In rare cases, the neutral conductor has an overcurrent‑protection, which must interrupt both neutral and non-earthed cables concurrently.

    Auxiliary power supply cabling

    IMPORTANT!
    An auxiliary power supply is required to operate the Fronius Smart Meter TS. The fuse (F) must comply with the national standards and guidelines as well as the dimensions of the conductors.

    Cabling

    IMPORTANT!
    Always switch off the power supply before connecting the mains voltage inputs to the Fronius Smart Meter TS.

    Recommended thickness of stranded mains voltage cables for the terminals of the measuring input and measuring output:
    • Wire: 1 - 4 mm²
    • Recommended torque: max. 0.6 Nm

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

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

    Selection criteria for current transformer

    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 converter 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 TS needs 0.5 VA to carry out its measurements. Losses also occur on the outgoing and return leads. The power of the current converter must be greater than the sum total of the power of the Fronius Smart Meter TS and the leads. The higher the power, the better.

    Example
    The length of the outgoing and return lead (0.5 m each) between the Fronius Smart Meter TS 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 TS is 0.5 VA.
    Line resistance 0.6 VA + self-consumption 0.5 VA = 1.1 VA
    → A current transformer with a rating of 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.

    Connecting the current transformers

    1Make 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.
    2Make sure that the current transformers are pointing in the correct direction. Observe the data sheet for the current transformer.
    3Note down the nominal current of the current transformer for each meter. These values will be required for setup.
    4Attach the current transformers to the conductor to be measured and connect the cables of the current transformer to the Fronius Smart Meter TS.

    IMPORTANT!
    Always switch off the power supply before disconnecting live conductors.
    5The current transformers are connected to connections 4 and 5; 6 and 7; 8 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.

    Suitable voltage transformers

    Only voltage transformers with a voltage range from 220 to 480 V (phase - phase) and from 100 to 277 V (phase - neutral conductor) may be used. The voltage transformers must be connected to terminals 1, 2, 3 and N at the point of direct voltage measurement.

    Connecting the data communication cable to the inverter

    Connect the data communication connections of the Fronius Smart Meter TS to the Modbus interface of the Fronius inverter using a network cable (type CAT5 or higher).

    Several Smart Meters can be installed in the system, see chapter Multi-meter system - Fronius SnapINverter on page (→).

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

    IMPORTANT!

    More information on successful commissioning.

    Note the following information about connecting the data communication cable to the inverter.
    • Use network cables of type CAT5 or higher.
    • Use a mutual twisted cable pair for corresponding data lines (D+/D-, M1+/M1-).
    • If the data lines are close to the mains cabling, use wires or cables that are designed for 300 to 600 V (never less than the operating voltage).
    • Use double-insulated or sheathed data lines when they are close to bare conductors.
    • Use shielded twisted pair cables to avoid faults.
    • Two wires can be installed in each terminal; the wires are twisted first, inserted into the terminal and tightened.
      Note: A loose wire can disable an entire area of the network.
    • The data communication connections of the Fronius Smart Meter TS are electrically isolated from hazardous voltages.

    A maximum of 4 Modbus participants can be connected to the Modbus terminal.

    IMPORTANT!
    Only one primary meter, one battery and one Ohmpilot can be connected per inverter. Due to the high data transfer of the battery, the battery occupies 2 participants.

    Multi-meter system - Fronius SnapINverter

    If several Fronius Smart Meter TS are installed, a separate address must be set for each (see Setting the address on the Fronius Smart Meter TS 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. Use 3 secondary meters in the system. To avoid interference, it is recommended to install the terminating resistors according to chapter Connecting the 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:
    • Only assign each Modbus address once.
    • Terminating resistors must be positioned individually for each channel.
