5. Instalace

Follow these steps carefully for proper installation of the Smart Energy Monitor.

5.1 Wiring the Main Unit

1. Odpojit napájení: Before starting, ensure the main power supply to your electrical panel is completely shut off at the circuit breaker.
2. Montáž zařízení: Mount the Smart Energy Monitor main unit onto a 35MM DIN rail within your electrical panel.
3. Připojte vstup napájení: Connect the Live (L) and Neutral (N) wires from your main power supply to the corresponding 'L' and 'N' terminals on the energy monitor. The input voltage range is AC 90-250V.

5.2 Connecting CT Clamps

The device includes two 120A Current Transformer (CT) clamps for monitoring two separate circuits or phases.

1. Identify Circuits: Determine which circuits you wish to monitor. Each CT clamp will monitor one live wire.
2. Open CT Clamp: Open one CT clamp and place it around the live wire of the first circuit you want to monitor. Ensure the clamp is fully closed and secured. The arrow on the CT clamp should point in the direction of current flow (e.g., from the grid towards the load for consumption monitoring, or from solar inverter towards the grid for generation monitoring).
3. Connect CT Wires: Connect the wires from the first CT clamp to the 'Circuit 1' terminals (1+ and 1-) on the energy monitor. Pay attention to polarity if indicated on the clamp or wires.
4. Repeat for Second Clamp: Repeat the process for the second CT clamp, connecting its wires to the 'Circuit 2' terminals (2+ and 2-).

5.3 Schéma zapojení Example

Refer to the following diagram for a typical wiring configuration. This diagram illustrates how to connect the energy monitor and CT clamps within a single-phase electrical system.

Image 5.3: A schematic wiring diagram showing the Smart Energy Monitor connected to a circuit breaker (L and N lines) and two separate loads (Load1 and Load2) via the two CT clamps. Arrows indicate current flow.

Note on 220V Split Phase Wiring: For 220V split-phase circuits, ensure that the CT clamps are correctly oriented. If monitoring two legs of a 220V line, one set of wires should connect to the monitor with one polarity (e.g., red to 1+, black to 1-) and the other set with reversed polarity (e.g., black to 2+, red to 2-) to ensure correct total value calculation. Incorrect polarity may result in negative readings for one circuit, leading to inaccurate total consumption.

6. Nastavení a připojení aplikace

The Walfront Smart Energy Monitor integrates with the Tuya Smart or Smart Life application. Download the app from your mobile device's app store.

1. Stáhnout aplikaci: Hledat "Tuya Smart" or "Smart Life" in the App Store (iOS) or Google Play Store (Android) and install it.
