5. Setup and Installation

5.1 Installation Guidelines

The TOQ7 ATS is designed for easy installation due to its compact size. However, given its electrical nature, professional installation by a certified electrician is strongly recommended to ensure safety and compliance with all electrical standards.

• Choose a suitable mounting location that is dry, well-ventilated, and free from excessive vibration or extreme temperatures.
• Ensure adequate clearance around the device for ventilation and future maintenance.
• Mount the ATS securely using appropriate fasteners.

5.2 Wiring Diagram

Refer to the wiring diagram below for correct connection of the primary power source (Source A), backup power source (Source B), and the load. Pay close attention to the common incoming lines, standby incoming lines, common control lines, and zero line inputs.

Figure 5: Detailed wiring diagram for the FPBIGCHA TOQ7 ATS, illustrating connections for common incoming lines, standby incoming lines, control lines, zero lines, and load output.

• Source A: Connect your primary power supply (e.g., utility grid) to the 'Source A' terminals (R, S, T).
• Source B: Connect your backup power supply (e.g., generator) to the 'Source B' terminals (R, S, T).
• Load Output: Connect your electrical load to the 'Load output' terminals.
• Control and Zero Lines: Ensure correct connection of common control lines, common zero line input, standby incoming line, and standby zero line input as indicated in the diagram.
• Double-check all connections for tightness and correct polarity before applying power.

6. Operating Instructions

6.1 Operating Modes

The TOQ7 ATS features a selector switch on the front panel to choose between 'Manual' and 'Auto' operation.

• Auto Mode: In this mode, the switch will automatically transfer the load from Source A to Source B if Source A fails, and automatically transfer back to Source A when it is restored. This is the recommended mode for continuous, uninterrupted power.
• Manual Mode: In this mode, the power transfer must be initiated manually. This mode is typically used for testing, maintenance, or specific operational requirements.

Important Note: For manual operation, ensure the selector switch is firmly in the 'Manual' position before attempting to switch power sources.

6.2 Automatic Transfer Function

When the ATS is in 'Auto' mode:

1. The device continuously monitors the primary power source (Source A).
2. If Source A's voltage or frequency falls outside acceptable limits, the ATS will initiate a transfer.
3. After a brief delay, the load will be disconnected from Source A and connected to Source B (backup power).
4. When Source A is restored and stable, the ATS will automatically transfer the load back to Source A, ensuring the continuity of power supply.

7. Maintenance

Regular maintenance helps ensure the longevity and reliable operation of your ATS. Always disconnect all power sources before performing any maintenance.

• Visual Inspection: Periodically inspect the ATS for any signs of physical damage, loose connections, or overheating.
• Cleaning: Keep the device clean and free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners.
• Terminal Check: Ensure all terminal connections remain tight. Loose connections can lead to overheating and device failure.
• Functional Test: Periodically test the automatic transfer function by simulating a primary power failure (if safe to do so and with proper precautions).

8. Troubleshooting

If the ATS is not functioning as expected, consider the following basic troubleshooting steps. For complex issues, contact a qualified electrician.

• No Power to Load:
  • Check if both Source A and Source B are active.
  • Verify the ATS is in 'Auto' mode if automatic transfer is desired.
  • Inspect all wiring connections for looseness or damage.
• Failure to Transfer:
  • Ensure the backup power source (Source B) is operational and providing stable power.
  • Confirm the ATS is in 'Auto' mode.
  • Check for any error indicators on the device (if present).
• Overheating:
  • Ensure proper ventilation around the unit.
  • Check for loose connections, which can cause resistance and heat.
  • Verify the load does not exceed the rated current of the ATS.
