6. Installation and Setup
Follow these steps carefully to ensure a safe and watertight connection. Refer to the installation diagram (Figure 3) for visual guidance.
- Prepare Cables: Ensure the power supply is disconnected. For each cable, strip the outer insulation to expose the inner conductors (Live, Neutral, Earth). Strip approximately 8-10mm of insulation from the ends of the individual conductors.
- Disassemble Connector: Unscrew the glands and locking nuts from each of the three entry points of the connector. Remove the internal seals and set them aside.
- Insert Cables: Thread each cable through the gland, locking nut, and then through the corresponding entry point of the connector body. Ensure the cable passes through the internal seals correctly.
- Connect Wires: Insert the stripped ends of the Live, Neutral, and Earth wires into their respective screw terminals within the connector body. Ensure no stray strands are present and that the insulation reaches the terminal block. Tighten the terminal screws securely.
- Reassemble and Seal: Push the internal seals firmly into place around the cables at each entry point. Screw the locking nuts back onto the connector body, ensuring they are tight. Finally, screw the glands onto the locking nuts.
- Tighten Glands: Using an appropriate tool, tighten the glands to a torque of 2.5 Nm. This is crucial for maintaining the IP68 waterproof rating. Do not overtighten.

7. Operation
Once correctly installed and sealed, the Knightsbridge JB003 connector operates passively by providing a secure and waterproof junction for your electrical cables. There are no user-operable controls or settings on the connector itself. Ensure the connected electrical system is functioning as intended after installation.
8. Maintenance
To ensure the longevity and continued performance of your Knightsbridge JB003 connector, consider the following maintenance guidelines:
- Periodic Inspection: Regularly inspect the connector for any visible signs of damage, cracks, or degradation of the seals. Check for any signs of water ingress or corrosion.
- Gland Tightness: Periodically check that all cable glands remain securely tightened to maintain the IP68 rating.
- Cleaning: If necessary, clean the exterior of the connector with a damp cloth. Do not use abrasive cleaners or solvents.
- Environmental Factors: While designed for outdoor use, extreme environmental conditions (e.g., prolonged exposure to direct sunlight, extreme temperatures) can affect material lifespan.
9. Troubleshooting
If you encounter issues with your Knightsbridge JB003 connector, consider the following:
- No Power to Connected Device:
- Ensure the main power supply is active.
- Verify that all wire connections within the connector are secure and terminals are tightened.
- Check for continuity in the cables leading to and from the connector.
- Signs of Water Ingress:
- Immediately disconnect power.
- Carefully disassemble the connector and inspect all seals for proper seating and damage.
- Ensure the cable outer diameter falls within the specified range (5mm-14mm) for effective sealing.
- Reassemble, ensuring glands are tightened to the specified torque (2.5 Nm).
- Loose Connections:
- Disconnect power.
- Open the connector and re-tighten all screw terminals.
- Ensure sufficient conductor length is inserted into the terminals.
If problems persist, consult a qualified electrician or contact Knightsbridge customer support.
