1. Source A (City Power): Connect your primary power source (e.g., utility grid) to the 'Source A' input terminals. Ensure correct phase and neutral connections.
2. Source B (Generator/Secondary Power): Connect your secondary power source (e.g., generator, solar inverter output) to the 'Source B' input terminals.
3. Load Side: Connect your electrical load to the 'Load Side' output terminals.
4. Control Terminals (BR BN C NO): These terminals are typically used for remote status indication or external control. Consult the specific wiring diagram on the device for their exact function.
5. Ensure all screw terminals are tightened securely to prevent loose connections and arcing.

4.3 EWelink App Connection
