5. Installation

Before beginning installation, ensure that the main power supply to the circuit is disconnected and secured against accidental re-energization.

1. Mounting: Mount the remote switch onto a standard DIN rail within an appropriate electrical enclosure. Ensure it is securely clipped into place.
2. Wiring - Power Circuit: Connect the main power circuit wires to the designated screw terminals for the power contacts. Refer to the wiring diagram provided with the product packaging for specific terminal assignments. Ensure all connections are tight and secure.
3. Wiring - Control Circuit: Connect the 230V control circuit wires to the designated control terminals. This circuit will provide the impulse to operate the remote switch.
4. Verification: Double-check all wiring connections for correctness and tightness. Ensure no bare wires are exposed.
5. Restore Power: Once installation is complete and verified, restore power to the circuit.

6. Operating Instructions

The Legrand CX³ Standard Remote Switch 412412 operates by receiving an electrical impulse from a control device (e.g., a push button or timer). Each impulse will toggle the state of the switch's contacts.

• Switching ON: Apply a brief 230V impulse to the control terminals. The switch contacts will close, allowing current to flow through the power circuit.
• Switching OFF: Apply another brief 230V impulse to the control terminals. The switch contacts will open, interrupting the current flow in the power circuit.
• Manual Operation: This specific model is designed for remote (impulse) control. There is no direct manual override on the device itself.

7. Maintenance

The Legrand CX³ Standard Remote Switch is designed for long-term, reliable operation with minimal maintenance. However, periodic checks are recommended.

• Cleaning: Ensure the device is free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners or solvents.
• Connection Check: Periodically, with power disconnected, check the tightness of all screw terminals to ensure secure connections.
• Visual Inspection: Inspect the device for any signs of physical damage, discoloration, or overheating. If any issues are observed, disconnect power and consult a qualified electrician.

Always disconnect power before performing any maintenance.

8. Troubleshooting

If you experience issues with your remote switch, consider the following common troubleshooting steps:

• Switch Not Responding:
  • Verify that the control voltage (230V) is present at the control terminals when an impulse is sent.
  • Check the wiring connections for the control circuit for any loose or incorrect connections.
  • Ensure the control device (e.g., push button) is functioning correctly.
• No Power to Load:
  • Confirm that the main power supply to the circuit is active.
  • Check the power circuit wiring connections to the switch and to the load.
  • Ensure the remote switch has been successfully toggled to the 'ON' state by sending an impulse.
• Overheating/Burning Smell:
  • Immediately disconnect power. This indicates a serious issue. Do not attempt to operate the device. Contact a qualified electrician.

If problems persist after performing these checks, contact a qualified electrician or Legrand customer support.
