5. تعليمات التشغيل

The DEWIN G2R 63A 2P ATS supports both automatic and manual operation modes.

5.1 الوضع التلقائي

In automatic mode, the switch will detect the presence of the common power supply (I) and the backup power supply (II). If the common power fails, the switch will automatically transfer the load to the backup power supply. When common power is restored, it will switch back.

• Set the 'Auto/Manual' switch to 'Auto'.
• The indicator lights (I and II) will show which power source is active.
• The 'Load ON' indicator will illuminate when power is supplied to the load.

5.2 الوضع اليدوي

To manually switch between power sources:

1. Set the 'Auto/Manual' switch to 'Manual'.
2. Use the operating handle to physically switch between position I (Common Power) and position II (Backup Power).
3. Ensure the desired power source is selected and the corresponding indicator light is on.

6. الصيانة

The DEWIN G2R 63A 2P ATS is designed for reliable operation with minimal maintenance. However, periodic checks are recommended:

• التفتيش البصري: Regularly inspect the device for any signs of physical damage, loose connections, or overheating.
• تنظيف: Keep the device free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquids or abrasive cleaners.
• فحص الجهاز الطرفي: Periodically verify that all terminal screws are tight to prevent arcing and ensure good electrical contact.
