Installation must be performed by authorized and qualified personnel only.
All location-specific electrical wiring requirements and recommendations should be followed depending on the site of installation.
Suitable protection equipment should be installed on powering and voltage measurement rails (see next sections for details).
Always follow local regulations and recommendations when working with electrical appliances.
DotVision recommends use of a flat screwdriver of 2.5mm width for all terminals.
Warning: current measurement terminals are push type, do not try to screw these terminals. However, the same flat screwdriver can be used to push onto those terminals.
provided from a phase + neutral circuit.
Cabling should be accomplished with 0.5 to 0.75mm² cable. DotVision recommends use of multi-strand flexible cable with ferules on each end.
Power line must be protected according to selected cable section. DotVision recommends use of 0.2 to 2A protection of preferred type (circuit breaker or fuse).
Device is equipped with its own onboard fuse. This fuse acts as a security in case of overvoltage and is not replaceable by the end user. Contact DotVision if you think that the device fuse should be replaced.
Following diagram shows how Spoony should be connected to its power supply:
Device is suitable to measure up to three single-phase equipment.
This section covers the case of single-phase installation only. If you want to measure 3 single-phase equipment on a three-phase network, please follow next section (three-phase power measurement) recommendations regarding voltage and current channels identification.
When used in a single-phase electrical network, all voltage reference inputs (L1, L2 and L3) should be tied together, i.e., shorted.
In most cases, L1, L2 and L3 should be connected to L which allows the use of a single protection equipment to protect both power and measurement inputs.
N’ must be connected to neutral. In most case, N’ should also be tied to N.
Specific cases may require running separate line and neutral pairs to the device for powering and measurement, for example if measured line may be disconnected in normal use. It is not recommended to power the device from an intermittent power supply to avoid data loss. This specific case is not covered in this document.
Following figure shows typical connection of power and voltage measurement inputs in single-phase electrical networks:
DotVision recommends the use of two-cable ferrules to form the bridges between L, L1, L2, L3 and N, N’ as shown in the picture bellow:
Current sensors are then installed onto desired lines. DotVision provides only split-core current transformers or Rogowski coils which can be installed without unplugging the monitored line. Please refer to paragraph 3.1.5 for detailed procedure.
Device is suitable for multi or three-phase power measurement. Wiring differs from single-phase power measurement because phases must be properly identified:
Voltage on L1 must be from the same phase going through current sensor 1,
Voltage on L2 must be from the same phase going through current sensor 2,
Voltage on L3 must be from the same phase going through current sensor 3.
In most cases, phases are easily identified by their colors. However, it may be necessary to use a voltmeter to confirm phase number.
Measurement in three-phase electrical network can be achieved with or without neutral connection. Note however that a line + neutral connection is required for device powering.
If the monitored equipment has a neutral connection, it should be tied to neutral input (N’) on Spoony for optimal accuracy.
Following diagram shows typical connection of power and voltage measurement inputs in three-phase electrical network:
Current sensors are then installed onto lines going to the monitored equipment.
Be careful when identifying phases and make sure each current sensor is mounted onto the matching cable.
Please refer to paragraph 3.1.5 for detailed installation procedure of current sensors.
This paragraph covers current sensors installation in detail. Please refer to the paragraph matching your actual current sensor model.
All current sensors must be properly installed for optimal precision.
Always choose current sensors matching cable size and maximum current. Current transformers can be damaged if exposed to currents above their maximum rating.
All current sensor types have a mounting direction which must be respected for proper measurement.
This kind of current sensor is based on split-core current transformers. They can be opened for installation with the following instructions:
- Open the sensor,
- Identify mounting direction. All sensors have an arrow which must point to the load when installed (see illustration below),
- Place sensor around the cable and close the sensor. You should hear a click,
- Check if sensor is correctly closed by pulling slightly the top part,
- If possible, secure the sensor onto the cable using cable ties,
- Always secure sensor cables properly to avoid damage to the wires.
This kind of current sensor is based on Rogowski coils. They can be opened for installation and have the advantage of having greater mechanical flexibility, allowing easy installation onto bus bar for example.
A few precautions must be taken with this kind of sensor:
- Cables going to Spoony are coaxial cables and must be handled properly. Do not bend them, do not pull them,
- Sensors must be secured properly onto the primary conductor using cable ties,
- Measurement loop (flexible part going around the primary conductor) should be kept as far as possible from conductors other than the primary conductor. If unavoidable, limit the contact area with adjacent conductors as much as possible,
- Keep measurement loop perpendicular to the primary conductor as much as possible and avoid distorting the measurement loop. Ideally the measurement loop should be a perfect circle,
- As with current transformer, mounting direction is indicated by and arrow onto the body of the sensor. The arrow must point towards the load when installed.

1.8 Typical installation schematic, three-phase power measurement without neutral, separate line + neutral available for power supply
The device can be connected to your Local Area Network (LAN) through an ethernet connection.
RJ45 connector is situated on top of the device.
The device is equipped with a 10Base-T, 100Base-TX PHY interface with auto-negotiation and auto-MDIX enabled.
Please note that the device may be used in offline mode, which does not require network connection. However, in this case, the configuration will only be possible by directly accessing the microSD card inside the device. Refer to chapter 0 for details on device configuration.
Network connection can also be established through Wi-Fi (in option).
When installed, the Wi-Fi extension provides Wi-Fi access point (Wi-Fi AP) and station (Wi-Fi STA) functionality.
Refer to paragraph 4.3 for details.
Device is equipped with an RS485 bus allowing MODBUS client (master) or server (slave) functionality.
RS485 bus wiring must be done according to EIA-485. This includes usage of proper termination resistor and baud rate selection according to bus length and load.
Spoony provides a 3-terminal connector allowing wiring to the RS485 bus. Detailed view of this connector is shown below:
Desired MODBUS mode (client or server) must also be configured. Refer to section 4.6 for details.
Device is equipped with a TIC demodulator input. This input allows connection to most French electricity provider’s energy meters, including Linky and older generations of meters.
For proper functionality, the monitored meter must be configured in Teleinformation mode. Wiring should be realized using twisted-pair cable between the meter and the Spoony as shown onto the diagram below:
Note: TIC signal has no polarity requirement
TIC functionality must then be configured and enabled in Automation Service configuration. Refer to section 0 for details.
Device is equipped with 3 open-drain outputs with 12V/250mA driving capacity, as well as 3 12V output terminals with a total output capacity of 500mA.
These outputs (OUT A, OUT B and OUTC) can be used to drive relays or other compatible equipment, thus adding control capabilities to the device.
