Setup and Installation
1. Safety Precautions
- Ensure the main power supply is turned OFF before attempting any installation.
- Installation should be performed by a qualified electrician or a person with sufficient knowledge of electrical systems.
- Always follow local electrical codes and regulations.
2. Mounting the Monitor
The Refoss EM06 is designed for easy installation on a standard DIN rail within your electrical panel. Its compact size (7.3 x 5.2 x 2.45 cm) allows for convenient placement.
- Locate a suitable position on the DIN rail inside your electrical panel.

3. Wiring the Current Transformers (CTs)
The EM06 supports up to 6 current transformers for monitoring individual circuits. The CT line length is 90 cm.
- Voltage-current correspondence:
- Red CTs connect to A1, A2 channels.
- Green CTs connect to B1, B2 channels.
- Black CTs connect to C1, C2 channels.
- Carefully clamp each CT around the live wire of the circuit you wish to monitor. Ensure the CT is oriented correctly according to any arrows or markings on the CT itself, indicating the direction of current flow.
- Connect the CT cables to the corresponding input ports on the EM06 monitor.

4. Powering the Monitor
The EM06 requires a power supply of 100-240V~50/60Hz.
- Connect the power input of the EM06 to a suitable power source within the specified voltage range.
- Once powered, the device will initiate its startup sequence.
5. Initial Setup (Bluetooth & Wi-Fi)
The EM06 uses Bluetooth for initial setup and Wi-Fi for ongoing communication.
- Download the official Refoss app from your smartphone's app store (iOS/Android).
- Open the app and create an account or log in.
- Follow the in-app instructions to add a new device. The app will guide you through connecting to the EM06 via Bluetooth for initial configuration, including connecting it to your 2.4GHz Wi-Fi network (IEEE 802.11 b/g/n).
- Ensure your Wi-Fi network is stable and within range (up to 70 meters from the EM06 for optimal performance).
Operating Instructions
1. Real-time Energy Monitoring
Once connected, the Refoss app provides real-time data for each monitored channel.
- Open the Refoss app on your smartphone.
- Select your EM06 device to view the dashboard.
- The dashboard will display current power consumption (W), voltage (V), current (A), and power factor (PF) for each of the 6 channels.

2. Historical Data and Measurement Charts
The app allows you to review historical energy consumption data and visualize trends.
- Navigate to the "History" or "Charts" section within the EM06 device interface in the app.
- You can view power consumption per hour, day, and month.
- The data is stored for up to 36 months, enabling long-term analysis of your energy usage patterns.

3. Consumption Alarms and Data Export
- Consumption Alarm: Set custom thresholds for power consumption. If a monitored circuit exceeds the set limit, you will receive a notification, helping you identify and address energy waste.
- Data Export: The app provides functionality to export your energy consumption data. This can be useful for detailed analysis in external software or for sharing with energy auditors.
4. Monitoring Solar/Wind Power
The EM06 is capable of monitoring power generated by solar panels or wind power plants, allowing you to track your renewable energy production.

Maintenance
- Cleaning: Periodically wipe the exterior of the EM06 monitor with a dry, soft cloth. Do not use liquid cleaners or solvents.
- Firmware Updates: Ensure your device's firmware is up to date. The Refoss app will typically notify you of available updates. Follow the in-app instructions for safe updating.
- Connection Check: Regularly check the physical connections of the CTs and power supply to ensure they are secure.
- App Updates: Keep the Refoss app updated to the latest version for optimal performance and new features.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not powering on. | No power supply or incorrect voltage. | Check power connections and ensure the power supply is within 100-240V~50/60Hz. |
| Cannot connect to Wi-Fi. | Incorrect Wi-Fi password, 5GHz network, or weak signal. | Ensure you are connecting to a 2.4GHz Wi-Fi network. Double-check the password. Move the EM06 closer to the router or consider a Wi-Fi extender. |
| No energy data displayed. | CTs not correctly installed or connected. | Verify that the CTs are securely clamped around the correct wires and properly connected to the EM06. Check CT orientation. |
| Inaccurate readings. | CTs installed incorrectly (e.g., wrong direction) or faulty. | Recheck CT installation, especially the direction. If issues persist, contact support. |
