Setup and Installation
Follow these steps for proper installation of your deleyCON network socket set. Ensure power is disconnected before beginning any electrical work.
1. Prepare the Keystone Module

- Carefully detach the wiring block from the keystone module.
- Strip approximately 2-3 cm of the outer jacket from your network raw cable (e.g., CAT6a). Do not strip the individual wire insulation.
- Following the color code diagram on the wiring block (T568A or T568B, typically T568B for most installations), insert each individual wire into its corresponding slot. Ensure the wires are fully seated.
- Use a punch-down tool to secure the wires and trim any excess. If a punch-down tool is not available, some keystone modules allow for tool-less termination by pressing the cover firmly.
- Once all wires are terminated, reattach the wiring block to the keystone module. Ensure it clicks securely into place.
- Use the provided cable tie to secure the network cable to the keystone module, providing strain relief.
2. Assemble the Network Socket

- Insert the prepared keystone module into the metal mounting frame. It should snap into place.
- Attach the front cover plate to the mounting frame. Ensure it aligns correctly and snaps securely.

- Carefully push the assembled network socket into a standard flush-mounted wall box.
- Secure the socket to the wall box using appropriate screws (not included). Ensure it is firmly seated and level.
- Attach the outer decorative frame (if applicable and separate) to complete the installation.
Operating Instructions
Once the deleyCON CAT6a Network Socket is installed, its operation is straightforward:
- Connect one end of a standard RJ45 patch cable (e.g., CAT6a) to the RJ45 port on the installed network socket.
- Connect the other end of the patch cable to your network device (e.g., computer, router, switch).
- Verify network connectivity on your device.

Maintenance
The deleyCON CAT6a Network Socket requires minimal maintenance:
- Keep the RJ45 port clean and free from dust. Use compressed air if necessary.
- Avoid applying excessive force when inserting or removing patch cables to prevent damage to the port.
- Periodically check the physical connection for any signs of wear or damage.
Troubleshooting
If you experience issues with your network connection, consider the following troubleshooting steps:
- No Network Connectivity:
- Ensure both ends of the patch cable are securely connected.
- Test the patch cable with another device or replace it to rule out a faulty cable.
- Verify that the network raw cable was correctly terminated in the keystone module according to the T568A or T568B standard. Incorrect wiring is a common cause of connectivity issues.
- Check your network equipment (router, switch) to ensure it is powered on and functioning correctly.
- Slow Network Speed:
- Ensure all components in your network chain (cables, switches, router) are rated for CAT6a or higher to achieve optimal speeds.
- Check for any kinks or damage in the network raw cable or patch cable.
- Verify that the keystone module's shielding is properly grounded if applicable, to minimize interference.
