3. Informació de seguretat
WARNING: Installation involves working with high voltage electricity. For safety reasons, Refoss strongly recommends having a professional electrician handle the installation.
- Always turn off the main power to your electrical panel before beginning any installation work.
- Ensure all circuits are de-energized before handling wires or components.
- Do not touch any exposed wires or live parts.
- Seguiu tots els codis i regulacions elèctriques locals.
- Take care when accessing the included current transformers and avoid bumping them to prevent damage.
4. Configuració i instal·lació
This section provides detailed steps for installing your Refoss EM16 Smart Home Energy Monitor. For a comprehensive visual guide, please refer to the official installation video below.
4.1 Configuració inicial
- Apagueu l'alimentació: Before starting, turn off the main circuit breaker to your electrical panel.
- Place the Main Unit: Place the EM16 main unit in the electrical panel. Ensure it is at least 2 inches away from any live parts, excluding insulated components.
- Instal·leu l'antena: Create a small hole in the electrical panel to thread the antenna cable through. Insert the antenna cable into the labeled jack at the top of the energy monitor and tighten securely. Make sure the antenna is not enclosed within the panel, as this can cause signal interference.
- Plug in the Wire Harness: Insert the power harness into the top of the energy monitor until it snaps securely into place. This harness allows access to single-phase power, two-phase power, and three-phase power.
4.2 Wire Identification
Before connecting the current transformers, identify your electricity type:
- Single-phase, 3-wire systems: Typically have two hot wires (black and red) and one neutral wire (white). Common in U.S. residences, providing 240 volts (between the two hot wires) and 120 volts (between either hot wire and the neutral wire).
- Single-phase, 2-wire systems: Typically have one hot wire (black or red) and one neutral wire (white).
- Three-phase, 4-wire Wye systems: Typically have three hot wires (usually black, red, and blue) and one neutral wire (white). Common in commercial and industrial applications, not typical in residential settings.
Observe the main circuit breaker's rating to confirm your system type:
- Single-phase, 3-wire systems: The main circuit breaker is usually a 240-volt breaker.
- Single-phase, 2-wire systems: The main circuit breaker is typically a 120-volt breaker.
- Three-phase, 4-wire Wye systems: The main circuit breaker is typically a three-phase breaker and has a higher current rating.
4.3 Wiring Method (Example: Single-phase, 3-wire Systems)
This section demonstrates the installation using a single-phase, 3-wire system. For other wiring configurations, please refer to the provided video or consult a professional electrician.
- Connect the Neutral Wire: Connect the white wire from the power harness to the neutral bus bar in your electrical panel.
- Connect LA (Black Wire): Connect the black wire from the power harness to the A-phase circuit breaker. This provides power to the equipment and monitors the A-phase voltage. Snap the corresponding 60A current transformers (A1-A6) onto the A-phase wires to monitor the current.
- Connect LB (Red Wire): Connect the red wire from the power harness to the B-phase circuit breaker. This monitors the B-phase voltage. Snap the corresponding 60A current transformers (B1-B6) onto the B-phase wires to monitor the current.
- Connect LC (Blue Wire): If more circuits need to be monitored on the A-phase, connect the blue wire from the power harness to the A-phase circuit breaker. This monitors the A-phase voltage. Snap the corresponding 60A current transformers (C1-C6) onto the A-phase wires to monitor the current.
Important Note on Current Direction:
- When installing the current transformer, please pay attention to its orientation.
- For general consumption monitoring, ensure that the current direction is from K to L (arrow points away from the breaker).
- When monitoring the wiring of your solar feeder, ensure that the current direction is from L to K (arrow points towards the breaker).
- If the reading is opposite to the expected value (e.g., negative power), simply reverse the connection direction of the current transformer.
Connection Correspondence Table:
| EM16 Wire Color | Transformador de corrent |
|---|---|
| Black Wire (La Wire) | A1, A2, A3, A4, A5, A6 |
| Red Wire (Lb Wire) | B1, B2, B3, B4, B5, B6 |
| Blue Wire (Lc Wire) | C1, C2, C3, C4, C5, C6 |
| Filferro blanc | Neutre |
In addition, ensure the current transformer is correctly matched with its respective voltage collection line.
4.4 Insulate Empty Ports
Securely insert the supplied 2.5 mm insulation plugs into each empty port on the EM16 to ensure complete insulation.
4.5 Enceneu l'alimentació
Before covering your panel, take photos of the installation for your records or in case you need to contact support.
Restore power to all circuits by reattaching the electrical box panel and turning on all circuit breakers that were turned off during installation.
The unit's green LED should begin to flash slowly after 2 seconds. If the LED is flashing slowly, the unit is ready for configuration. If the LED is not blinking normally, press and hold the reset button for 5 seconds to reinitialize the unit.

7. Solució De Problemes
- Negative CT Readings: If your current transformer (CT) is showing a negative value, this may arise from incorrect wiring or settings. Fix it by inverting the current direction via the 'Circuit Factor' page in device settings within the Refoss app. No need to physically alter the current transformer. A firmware update may be required for this feature.
- LED Not Blinking Normally: If the green LED on the unit is not blinking slowly after power-on, press and hold the reset button for 5 seconds to reinitialize the unit.
- No hi ha dades a l'aplicació: Ensure the unit is properly connected to your Wi-Fi network. Check the Wi-Fi antenna connection and ensure it's not enclosed within the panel. Verify all current transformers are securely fastened and plugged into the correct ports.
- Lectures inexactes: Ensure all current transformers are correctly oriented (K to L for consumption, L to K for solar feed-in). Check that the correct current transformer is matched with its respective voltage collection line as per the correspondence table.
