Product Operate Guide

Start by downloading the Tuya APP, complete enterprise account registration and login for batch project management.

Wire the device per the standard diagram: connect the upper terminal to the three-phase power supply, lower terminal to the industrial load; power on and wait for the indicator to activate.

10 seconds after power-on, press and hold the pairing button until the WIFI indicator flashes, noting that only 2.4G WIFI is supported for pairing.

Click the "+" icon in the Tuya APP to enter the device adding interface, and wait for automatic device detection.

Select the target 2.4G WIFI network, input the password, and proceed with pairing.

Wait for pairing completion, and follow the prompts to complete initial configuration.

Create device groups, label names by workshop or area, and finish industrial project deployment.
