4. Setup and Installation
This section outlines the general steps for assembling the cable mount plug. Specific wiring diagrams may vary based on your application and should be consulted separately.
- Prepare the Cable: Strip the outer jacket of the cable to the appropriate length, exposing the individual insulated wires. Strip the insulation from the ends of the wires according to the screw terminal requirements.
- Thread Components: Slide the coupling nut and cable gland nut onto the cable in the correct order.
- Wire Termination: Connect each wire to its corresponding screw pin contact within the connector insert. Ensure proper polarity and secure tightening of the screws. The 3+PE configuration typically includes three power contacts and one protective earth contact.
- Assemble Insert: Carefully insert the wired contact assembly into the main plug body, ensuring proper alignment and seating.
- Secure Cable: Tighten the cable gland nut onto the plug body to provide strain relief and environmental sealing for the cable.
- Final Assembly: Ensure all components are securely fastened.
5. Operating Instructions
To connect the C01620H00310012 plug to a compatible receptacle:
- Alignment: Align the keyways or polarization features of the plug with those of the receptacle.
- Insertion: Gently push the plug into the receptacle until the contacts engage.
- Coupling: Rotate the threaded coupling nut clockwise until it is fully tightened. This ensures a secure mechanical and electrical connection and maintains environmental sealing. Do not overtighten.
To disconnect:
- Disconnect Power: Ensure power to the circuit is OFF before attempting to disconnect.
- Unscrew Coupling: Rotate the threaded coupling nut counter-clockwise until it is loose.
- Withdraw Plug: Gently pull the plug straight out from the receptacle. Avoid twisting or yanking the cable.
6. Maintenance
Regular maintenance helps ensure the longevity and reliability of the connector.
- Inspection: Periodically inspect the connector for signs of wear, damage, corrosion, or loose connections. Check the cable entry for proper sealing.
- Cleaning: If necessary, clean the connector contacts and housing with a dry, lint-free cloth. For stubborn dirt, use a contact cleaner specifically designed for electrical components, ensuring it is non-conductive and leaves no residue. Ensure the connector is completely dry before re-energizing.
- Tightness: Verify that the coupling nut and cable gland nut remain securely tightened.
7. Troubleshooting
If you encounter issues with your connector, consider the following common troubleshooting steps:
- No Electrical Connection:
- Check if the plug is fully inserted and the coupling nut is securely tightened.
- Inspect for damaged or bent contacts.
- Verify proper wire termination at the screw pins.
- Ensure power supply is active.
- Intermittent Connection:
- Tighten the coupling nut.
- Inspect for loose wire connections at the screw pins.
- Check for corrosion or debris on contacts and clean if necessary.
- Difficulty Connecting/Disconnecting:
- Ensure proper alignment of keyways.
- Check for physical damage or deformation of the connector housing or pins.
If problems persist, contact a qualified electrician or Amphenol technical support.
