Product Features
- Conductors: 24k Gold-plated α (Alpha) pure-copper for optimal signal transfer.
- Earth (Ground) Jumper System: Patented design (US Patent No.: 6,669,491) for enhanced grounding.
- Body Material: Nylon/fiberglass incorporating carbon particles to absorb vibration and resonance.
- Cable Compatibility: Specified for cable diameters from 6.6mm to 17.5mm.
- Cable Clamp: Metal cable clamp designed to improve grip and reduce mechanically and electrically induced distortion.
Setup and Installation
Proper installation is crucial for optimal performance and safety. It is recommended that installation be performed by a qualified technician if you are unfamiliar with electrical wiring.
Required Tools (Not Included):
- Wire strippers
- Screwdriver set (appropriate for terminal screws)
- Multimeter (for continuity testing, optional but recommended)
Installation Steps:
- Safety First: Ensure the power cable is disconnected from any power source before beginning installation.
- Prepare Cable: Carefully strip the outer jacket of your power cable to expose the internal conductors (Live, Neutral, Ground). Strip approximately 10-15mm of insulation from each conductor.
- Disassemble Connector: Unscrew and remove the rear housing and the internal assembly from the main body of the FI-28(G) connector.
- Insert Cable: Thread the prepared power cable through the rear housing and the metal cable clamp.
- Connect Conductors: Securely attach each conductor to its corresponding terminal on the internal assembly. Typically, Live (brown/black) to the 'L' terminal, Neutral (blue/white) to the 'N' terminal, and Ground (green/yellow) to the 'E' (Earth) terminal. Ensure no stray strands of wire are present.
- Secure Cable Clamp: Tighten the screws on the metal cable clamp to firmly grip the outer jacket of the power cable, preventing strain on the internal connections.
- Reassemble Connector: Carefully slide the internal assembly back into the main body and secure the rear housing. Ensure all parts are tightly fastened.
- Final Check: Visually inspect all connections for proper seating and ensure no bare wires are exposed.
Operating Instructions
Once the Furutech FI-28(G) IEC Connector is properly installed on a power cable, its operation is straightforward.
- Connect to Device: Insert the FI-28(G) connector firmly into the IEC inlet of your compatible electrical device (e.g., amplifier, AV receiver, speaker, high-end audio equipment).
- Connect to Power Source: Plug the other end of your power cable into a suitable AC power outlet.
- Power On: Turn on your electrical device as per its own operating instructions.
The connector is rated for 10A 250V AC or 15A 125V AC. Ensure that the connected device's power requirements do not exceed these ratings.
Maintenance
The Furutech FI-28(G) IEC Connector is designed for durability and requires minimal maintenance. Regular inspection can help ensure continued performance.
- Cleaning: Periodically wipe the exterior of the connector with a soft, dry cloth to remove dust and debris. Avoid using harsh chemicals or abrasive cleaners.
- Inspection: Regularly check the connector and the attached cable for any signs of physical damage, such as cracks, frayed wires, or loose connections.
- Connection Integrity: Ensure the connector remains firmly seated in the device's IEC inlet and the power outlet.
Troubleshooting
If you experience issues with your electrical device after installing the FI-28(G) connector, consider the following troubleshooting steps:
- No Power to Device:
- Verify that the power cable is securely plugged into both the FI-28(G) connector and the wall outlet.
- Ensure the FI-28(G) connector is fully inserted into the device's IEC inlet.
- Check the wall outlet with another device to confirm it is supplying power.
- Inspect the power cable and the connector for any visible damage.
- Intermittent Power:
- Ensure all internal wire connections within the FI-28(G) connector are tight and secure.
- Check for any loose connections at the wall outlet or device inlet.
If problems persist, consult a qualified electrician or contact Furutech customer support.
