5. Орнотуу жана орнотуу

The NLQ3-125/4P ATS is designed for track installation and is compatible with PZ30 power distribution boxes. Before proceeding with installation, ensure all power is disconnected at the main breaker.

Орнотуу кадамдары:

1. Текшерүү: Before installation, carefully inspect the ATS for any signs of damage. Use the operating handle to manually switch it on and off to check the flexibility of the transmission mechanism. Verify the generation and disconnection conditions of the load at each stage for both normal and standby power supplies.
2. Монтаждоо: Mount the ATS securely onto a DIN rail within your PZ30 power distribution box or suitable enclosure.
3. Wiring Main Power (Source A): Connect the main power supply (Normal Power) to the terminals labeled 'Source A'. Ensure correct phase (R, S, T) and neutral (N) connections for 4-pole systems.
4. Wiring Standby Power (Source B): Connect the standby power supply (Generator) to the terminals labeled 'Source B'. Ensure correct phase (R, S, T) and neutral (N) connections.
5. Wiring Load: Connect the load (your electrical system) to the output terminals of the ATS.
6. Башкаруу зымдары: Connect any necessary external control signals to the AR, AN, NC, C1, OFF (for Source A) and BR, BN, NC, C1, OFF (for Source B) terminals as per your system requirements.
7. Текшерүү: Double-check all wiring for correctness and tightness. Ensure no loose connections are present.

Экологиялык шарттар:

• Айлана-чөйрөнүн температурасы: Maximum 40°C, minimum -5°C. The average temperature within 24 hours should not exceed 35°C.
• Бийиктиги: Installation site altitude should not be higher than 2000m.
• Салыштырмалуу нымдуулук: At 40°C, relative humidity should not exceed 50%. At -5°C, higher humidity is permissible (e.g., 90% at 25°C). Special measures may be needed to address occasional condensation due to temperature changes.

6. Иштөө нускамалары

The NLQ3-125/4P ATS offers both automatic and manual operation modes.

Автоматтык режим:

• Set the selector switch to the 'Auto' position.
• In this mode, the ATS will continuously monitor the main power supply (Source A).
• If Source A fails or becomes abnormal, the ATS will automatically switch to the standby power supply (Source B) within milliseconds.
• When Source A is restored and stable, the ATS will automatically switch back to Source A.
• The indicator lights (A or B) will show which power source is currently active.

Кол режими:

• Set the selector switch to the 'Manual' position.
• In manual mode, the user can manually switch between Source A and Source B using the operating handle.
• This mode is typically used for testing, maintenance, or in situations where automatic switching is not desired.
• Эскертүү: Ensure the manual operation is performed carefully and safely, especially when power is connected.

7. Техникалык тейлөө
