4. Setup

4.1 Installation

The XPR3SS 3P4W Energy Meter is designed for DIN rail mounting. Ensure proper wiring for a 3-phase, 4-wire system (3P4W) and compatibility with 380V systems if applicable. Refer to the wiring diagram provided with the product packaging for specific connection details.

• Mount the meter securely on a standard DIN rail in an appropriate electrical enclosure.
• Connect the three phase lines (L1, L2, L3) and the neutral line (N) to the corresponding terminals.
• Ensure all connections are tight and secure to prevent loose contacts and potential hazards.
• Verify correct input and output connections for bidirectional measurement.

4.2 App Connection (Smart Life / Tuya App)

To enable smart features, connect the meter to your WiFi network using the Smart Life or Tuya App.

• Download the Smart Life or Tuya Smart app from your mobile device's app store.
• Register or log in to your account.
• Ensure your mobile device is connected to a 2.4GHz WiFi network.
• Power on the energy meter. The WiFi indicator on the meter should blink, indicating pairing mode. If not, refer to the product's quick start guide for manual pairing mode activation.
• In the app, tap '+' to add a device, then select 'Electrical Engineering' > 'Energy Meter (Wi-Fi)'.
• Follow the on-screen instructions to connect the meter to your WiFi network.
• Once connected, the WiFi indicator on the meter will become solid.
