4. سيٽ اپ ۽ تنصيب
Before proceeding, ensure power is disconnected as per Section 2, "Safety Information."
4.1 چڙهڻ
- 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 وائرنگ
The contactor features screw terminals for secure electrical connections. Refer to the markings on the device for correct wiring.
- Coil Terminals (Control Circuit): ڪنٽرول حجم سان ڳنڍيوtage (230V AC) to terminals A1 ۽ 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 ۽ 3.
- Connect the load to terminals 2 ۽ 4.
- پڪ ڪريو ته سڀئي ڪنيڪشن تنگ ۽ محفوظ آهن ته جيئن رابطن کي ڍلو ٿيڻ ۽ گرم ٿيڻ کان روڪيو وڃي.
- Double-check all wiring against the electrical diagram of your installation before restoring power.
5. آپريٽنگ هدايتون
Once installed and wired correctly, the contactor operates by applying voltage to its control coil (A1-A2).
- خودڪار آپريشن: جڏهن ڪنٽرول 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.
- دستي اوور رائڊ: 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. سار سنڀال
The Legrand 412544 CX3 Contactor is designed for reliable, long-term operation with minimal maintenance. However, periodic checks are recommended.
- بصري چڪاس: جسماني نقصان، رنگ بدلجڻ، يا ڍڪيل ڪنيڪشن جي ڪنهن به نشاني لاءِ وقتي طور تي ڪانٽيڪٽر جو معائنو ڪريو.
- ٽرمينل سختي: Ensure all screw terminals remain tight. Loose connections can lead to overheating and potential failure.
- صفائي: If necessary, gently clean the exterior of the contactor with a dry, lint-free cloth. Do not use liquids or abrasive cleaners.
- ڪارڪردگي چيڪ: With power disconnected from the load circuit, test the manual override function to ensure smooth operation.
اهم: ڪنهن به سار سنڀال ڪرڻ کان اڳ هميشه بجلي بند ڪريو.
