5. Setup & Installation
Follow these steps to properly install the double-wire plug-in connectors:
- Prepare Wires: Ensure the wires are stripped to the appropriate length, exposing the conductor without damaging the strands.
- Lift Control Valve: Gently lift the transparent control valve on the connector.
- Insert Wire: Insert the stripped wire into the connector's opening. Ensure the wire is fully seated.
- Secure Connection: Press the control valve down firmly with flat-mouth clips or pliers until it locks into place, securing the wire.
- Connect Halves: Align the two connector halves and push them together until they click, forming a secure connection.

Adjusting for Thicker Wires
If you encounter a slightly thicker wire that does not fit easily, you can adjust the connector:
- Locate the small plastic ring inside the wire entry point.
- Carefully cut this ring with scissors to create more space for the wire.

6. Operation
Once installed, the connectors provide a secure and reliable electrical connection. The locking buckle mechanism ensures the connection remains stable. Each connector is designed with independent shrapnel for different wires, allowing for quick and efficient wiring.

7. Maintenance
These connectors are designed for durability and require minimal maintenance. To ensure optimal performance and longevity:
- Periodically inspect connections for any signs of damage or loosening.
- Keep connectors clean and free from dust, dirt, and debris.
- Avoid exposing connectors to harsh chemicals or solvents.
- Store unused connectors in a dry, cool place.
8. Troubleshooting
If you encounter issues with your SAVITA Double-Wire Plug-In Connectors, consider the following:
- Loose Connection: Ensure the control valve is fully pressed down and locked. Re-insert the wire if necessary, ensuring it is stripped to the correct length and fully seated.
- Wire Not Fitting: Verify the wire's AWG and diameter are within the specified range (22-20 AWG, ID 0.025-0.04in, OD 0.062-0.08in). If slightly thicker, refer to the 'Adjusting for Thicker Wires' section (Image 5.2).
- No Power Flow: Double-check all connections in the circuit. Ensure the power source is active and the wires are correctly inserted into the connectors. Verify that the wire insulation is not interfering with the connection.
- Connector Damage: If a connector appears physically damaged, replace it immediately. Do not attempt to repair damaged connectors.
9. Wide Application
These wire connectors are versatile and widely used in various low-voltage applications, including but not limited to:
- Ceiling fans
- Sockets and switches
- Speakers
- LED lighting (e.g., strip lights, decorative lights)
