4. Postavljanje i instalacija

Before proceeding, ensure power is disconnected as per Section 2, "Safety Information."

4.1 Montaža

1. Locate an appropriate position on a standard DIN rail within an electrical enclosure.
2. Clip the contactor onto the DIN rail. Ensure it is securely fastened.

4.2 Ožičenje

The contactor features screw terminals for secure electrical connections. Refer to the markings on the device for correct wiring.

• Coil Terminals (Control Circuit): Povežite kontrolni voltage (230V AC) to terminals A1 i A2. A1 is typically for the phase/live wire, and A2 for the neutral.
• Main Contacts (Power Circuit):
  • Connect the incoming power supply to terminals 1 i 3.
  • Connect the load to terminals 2 i 4.
• Provjerite da su svi spojevi čvrsti i sigurni kako biste spriječili labave kontakte i pregrijavanje.
• Double-check all wiring against the electrical diagram of your installation before restoring power.

5. Uputstvo za upotrebu

Once installed and wired correctly, the contactor operates by applying voltage to its control coil (A1-A2).

• Automatski rad: Kada se kontrolni voltage (230V AC) is applied to terminals A1 and A2, the contactor coil energizes, closing the main contacts (1-2 and 3-4). This allows power to flow to the connected load. When the control voltage is removed, the coil de-energizes, and the contacts open, disconnecting the load.
• Ručno poništavanje: The contactor is equipped with a manual override lever on the front panel.
  • Move the lever to the 'AUTO' position for normal automatic operation via the control circuit.
  • Move the lever to the 'O' (Off) position to manually open the contacts, regardless of the control circuit status. This can be used for maintenance or to ensure the load remains off.
  • Some models may also feature a manual 'ON' position for continuous closure of contacts, independent of the control circuit. Refer to the specific markings on your device.

6. Održavanje

The Legrand 412544 CX3 Contactor is designed for reliable, long-term operation with minimal maintenance. However, periodic checks are recommended.

• Vizuelni pregled: Povremeno provjeravajte kontaktor na bilo kakve znakove fizičkog oštećenja, promjene boje ili labavih spojeva.
• Zategnutost terminala: Ensure all screw terminals remain tight. Loose connections can lead to overheating and potential failure.
• čišćenje: If necessary, gently clean the exterior of the contactor with a dry, lint-free cloth. Do not use liquids or abrasive cleaners.
• Provjera funkcionalnosti: With power disconnected from the load circuit, test the manual override function to ensure smooth operation.

Važno: Uvijek isključite napajanje prije bilo kakvog održavanja.
