2. Safety Information
WARNING: Electrical installation and maintenance should only be performed by a qualified professional. Failure to follow these instructions may result in electric shock, fire, or other serious injury.
- Always turn off all power supplies at the main circuit breaker before attempting any installation or wiring to ensure safety.
- Do not touch terminals or live wires during testing or operation.
- Ensure the device is installed in a dry environment, away from moisture and extreme temperatures.
- Verify that the voltage and current ratings of your electrical system are within the device's specifications (90-250VAC, 80A).
3. Product Components
The OWON Energy Monitor package typically includes:
- OWON Wi-Fi Bi-directional Home Energy Monitor unit (PC311-TY)
- One 80A Current Clamp Transformer (CT)
- User Manual (this document)

4. Setup and Installation
Follow these steps for safe and correct installation of your energy monitor.
4.1 Pre-installation Checklist
- Ensure you have basic electrical knowledge or consult a qualified electrician.
- Confirm your electrical system is single-phase.
- Have necessary tools: screwdriver, wire strippers, multimeter (optional).
- Ensure a stable 2.4 GHz Wi-Fi network is available at the installation location.
4.2 Physical Installation
- Power Off: Locate your main circuit breaker and turn off the power to the circuit where you intend to install the monitor. Verify power is off using a voltage tester.
- Mount the Monitor: The OWON Energy Monitor is designed to fit on standard 35mm DIN rails. Securely attach the monitor unit to the DIN rail within your electrical panel.
- Wire the Power Supply: Connect the Live (L) and Neutral (N) wires from your circuit breaker to the corresponding L and N terminals on the energy monitor. Input voltage range is 90-250VAC.
- Install the Current Clamp (CT):
- The CT must only be clamped around the Live wire of the circuit you wish to monitor. Do not clamp it around both live and neutral wires, or only the neutral wire.
- Connect the CT's output wires to the 'Circuit 1' terminals (1- and 1+) on the energy monitor.
- Direction of Current Flow: The arrow on the CT clamp indicates the direction of current flow. For measuring energy consumption, the arrow should point in the direction of the current flow (e.g., from grid to load). For measuring energy generation, the arrow should point opposite to the current flow (e.g., from inverter to grid).

- Wiring Diagrams: Refer to the following diagrams for specific wiring scenarios. Ensure the circuit measured by the CT is in the same phase as the circuit powering the PC311 monitor.

4.3 App Setup (Tuya Smart Life)
- Download App: Download the 'Tuya Smart' or 'Smart Life' app from your mobile device's app store.
- Register/Login: Create an account or log in to your existing account.
- Add Device: Restore power to the circuit. The monitor should enter pairing mode (usually indicated by a blinking LED). In the app, tap '+' to add a new device. Select 'Electrical' > 'Power Clamp' or 'Energy Monitor'.
- Connect to Wi-Fi: Follow the in-app instructions to connect the monitor to your 2.4 GHz Wi-Fi network. You will need to enter your Wi-Fi password.
- Configuration: Once connected, you can name the device and assign it to a room. The app will then display real-time energy data.
5. Operating Instructions

7. Troubleshooting
If you encounter issues with your OWON Energy Monitor, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not powering on | No power to L/N terminals; incorrect wiring. | Check circuit breaker. Verify L/N wiring connections. Ensure power is restored. |
| Cannot connect to Wi-Fi / App | Incorrect Wi-Fi password; 5GHz Wi-Fi network; weak Wi-Fi signal; device not in pairing mode. | Ensure correct 2.4 GHz Wi-Fi password. Move device closer to router. Reset device to enter pairing mode (refer to app instructions for reset method). |
| No energy data displayed | CT clamp not installed correctly; CT wires loose; no current flowing through monitored wire. | Verify CT clamp is securely attached to the live wire only. Check CT wire connections to the monitor. Ensure there is active power consumption/generation in the monitored circuit. |
| Inaccurate readings | CT clamp direction incorrect; CT clamp not fully closed; interference. | Check the CT arrow direction relative to current flow. Ensure the CT clamp is fully closed. Relocate if possible to avoid strong electromagnetic interference. |
If the problem persists after attempting these solutions, please contact OWON customer support.
