4. सेटअप आणि स्थापना
Before proceeding, ensure power is disconnected as per Section 2, "Safety Information."
4.1 माउंटिंग
- Locate an appropriate position on a standard DIN rail within an electrical enclosure.
- Clip the contactor onto the DIN rail. Ensure it is securely fastened.
4.2 वायरिंग
The contactor features screw terminals for secure electrical connections. Refer to the markings on the device for correct wiring.
- Coil Terminals (Control Circuit): नियंत्रण व्हॉल्यूम कनेक्ट कराtage (230V AC) to terminals A1 आणि 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 आणि 3.
- Connect the load to terminals 2 आणि 4.
- संपर्क सैल होणे आणि जास्त गरम होणे टाळण्यासाठी सर्व कनेक्शन घट्ट आणि सुरक्षित असल्याची खात्री करा.
- Double-check all wiring against the electrical diagram of your installation before restoring power.
5. ऑपरेटिंग सूचना
Once installed and wired correctly, the contactor operates by applying voltage to its control coil (A1-A2).
- स्वयंचलित ऑपरेशन: जेव्हा नियंत्रण व्हॉल्यूमtage (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.
- मॅन्युअल ओव्हरराइड: 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. देखभाल
The Legrand 412544 CX3 Contactor is designed for reliable, long-term operation with minimal maintenance. However, periodic checks are recommended.
- व्हिज्युअल तपासणी: शारीरिक नुकसान, रंगहीनता किंवा सैल कनेक्शनच्या कोणत्याही लक्षणांसाठी कॉन्टॅक्टरची वेळोवेळी तपासणी करा.
- टर्मिनल घट्टपणा: Ensure all screw terminals remain tight. Loose connections can lead to overheating and potential failure.
- स्वच्छता: If necessary, gently clean the exterior of the contactor with a dry, lint-free cloth. Do not use liquids or abrasive cleaners.
- कार्यक्षमता तपासणी: With power disconnected from the load circuit, test the manual override function to ensure smooth operation.
महत्त्वाचे: कोणतीही देखभाल करण्यापूर्वी नेहमी वीज खंडित करा.
