TAXNELE TXATS3-63A/4P Din Rail Automatic Transfer Switch User Manual

1. Introduction

This manual provides essential information for the safe and efficient installation, operation, and maintenance of the TAXNELE TXATS3-63A/4P Din Rail Automatic Transfer Switch (ATS). The TXATS-3 is a PC class infrequent change-over switch designed for AC systems with 50-60Hz frequency and a rated current of 6A-63A. Its primary function is to automatically switch to a backup power supply (Power B) when the main power (Power A) fails, ensuring an uninterrupted power supply with a switching speed of less than 50 milliseconds. When both power sources are available, Power A is prioritized.

2. Safety Information

Please read and understand all safety instructions before installing, operating, or performing maintenance on the ATS. Failure to follow these instructions may result in electric shock, fire, serious injury, or death.

• Installation and maintenance should only be performed by qualified electricians.
• Ensure all power sources are disconnected before beginning any installation or wiring work.
• Use appropriate personal protective equipment (PPE) such as insulated gloves and safety glasses.
• Verify correct wiring connections to prevent damage to the device and connected equipment.
• Do not operate the ATS if it appears damaged or malfunctions.
• The device must be installed in an enclosure that provides adequate protection against environmental factors.

5. Installation (Setup)

The TAXNELE TXATS3-63A/4P ATS is designed for 35mm standard DIN rail installation. Ensure all power is off before proceeding with installation.

5.1 Mounting

1. Select a suitable location within an electrical cabinet or distribution panel that provides adequate ventilation and protection.
2. Align the ATS with the 35mm DIN rail.
3. Press the ATS firmly onto the DIN rail until it clicks into place, ensuring it is securely mounted.

The ATS units are shown mounted inside a household lighting distribution box, demonstrating how they integrate into an existing electrical setup. The text overlay highlights "35MM STANDARD RAIL INSTALLATION."

5.2 Wiring

Refer to the wiring diagram below for proper connection of common power, backup power, and load outputs. Ensure all connections are tight and secure.

Image Description: A simplified wiring diagram for the ATS. It shows the connections for "Common power" (input I) and "Backup power" (input II) leading to the respective terminals. The "Load" output is shown connected from the bottom terminals. Blue lines indicate neutral connections, and red lines indicate live connections for both input sources and the load.

• Connect the main (common) power supply to terminals N1 A1 (neutral) and C1 B1 (live) under section 'I'.
• Connect the backup power supply to terminals N2 A2 (neutral) and C2 B2 (live) under section 'II'.
• Connect the load to terminals NA (neutral) and BC (live) at the bottom of the ATS.
• Double-check all wiring for correctness and tightness before restoring power.

6. Operation

The TXATS3-63A/4P ATS can operate in both automatic and manual modes.

6.1 Automatic Mode

1. Set the Auto/Manual switch to the "AUTO" position.
2. When the common power supply (Power A) is present, the ATS will automatically connect the load to Power A. The green "Common power supply" indicator will illuminate.
3. If Power A fails, the ATS will detect the outage and automatically switch the load to the backup power supply (Power B) within 50 milliseconds. The red "Backup power supply" indicator will illuminate.
4. When Power A is restored, the ATS will automatically switch the load back to Power A, prioritizing the common power source.

Image Description: This image highlights the automatic switching capability of the ATS, stating "AUTOMATIC SWITCHING AFTER POWER OFF <50MS". It visually represents the rapid transfer function, ensuring minimal interruption to power supply.

6.2 Manual Mode

In manual mode, the power source can be selected using the manual operation handle.

1. Set the Auto/Manual switch to the "MANU" position.
2. Use the manual operation handle to select between Power I (Common Power) and Power II (Backup Power).
3. The corresponding indicator light (green for Power I, red for Power II) will illuminate.
4. Caution: Ensure the load can handle the selected power source when operating in manual mode.

7. Maintenance

Regular maintenance helps ensure the longevity and reliable operation of your ATS.

• Periodic Inspection: Visually inspect the ATS and its connections periodically for any signs of damage, loose wiring, 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.
• Connection Check: Ensure all terminal connections remain tight. Loose connections can lead to overheating and malfunction.
• Function Test: Periodically test the automatic transfer function by simulating a main power failure (if safe to do so and permitted by your electrical setup).
• Professional Service: For any complex issues or internal repairs, contact a qualified electrician or the manufacturer's support.
