4. Setup and Installation
Follow these steps for proper installation of the ATS Dual-Power Transfer Switch:
- Mounting: Securely mount the transfer switch to a stable surface using the provided mounting holes on the steel frame base.
- Power Disconnection: Before making any electrical connections, ensure that all power sources (Normal Power and Backup Power) are completely disconnected and locked out.
- Wiring Connections: Refer to the wiring diagram below for correct connections.
- Connect the Common Incoming Line and Common Zero Line from your primary power source (e.g., City Power) to the "N Normal power" terminals.
- Connect the Backup Live Wire and Spare Neutral Line from your backup power source (e.g., Generator, Photovoltaic) to the "R Backup power" terminals.
- Connect the Load Output terminals to your electrical load.
- Connect the Common Control and Standby Control Line as indicated for automatic operation.
- Cable Verification: Double-check all wiring connections to ensure they are secure and correctly terminated.
- Initial Power-Up: Once all connections are verified, restore power to the primary source first, then the backup source.

It provides examples for connecting City Power, Generator, and Photovoltaic sources. Ensure all connections match the diagram for safe and correct operation.
5. Operating Instructions
The ATS transfer switch offers both automatic and manual operation modes:
5.1 Automatic Mode
In automatic mode, the switch will detect the presence of power from the primary source. If the primary power fails, it will automatically switch to the backup power source (if available). When primary power is restored, it will switch back.
- Ensure both primary and backup power sources are connected.
- Set the selector switch on the front panel to "Auto".
- The device will now automatically manage power transfer.
5.2 Manual Mode
Manual mode allows you to manually select between the primary and backup power sources.
- To switch manually, first turn the selector switch to the "O" (Off) position.
- Then, turn the selector switch to "Manual".
- Use the handle to select either "Normal power" (Source A) or "Backup power" (Source B).
- Important: Never switch power sources under load in manual mode. Always ensure the load is disconnected or the switch is in the "O" position before changing sources manually.

6. Maintenance
The ATS Automatic Transfer Switch is designed for durability and requires minimal maintenance. However, regular checks can ensure optimal performance and longevity:
- Visual Inspection: Periodically inspect the switch for any signs of physical damage, loose connections, or discoloration.
- Cleanliness: Keep the device clean and free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquids or abrasive cleaners.
- Connection Integrity: Ensure all terminal connections remain tight. Re-tighten if necessary, but only after disconnecting all power.
- Environmental Check: Ensure the operating environment remains dry and within specified temperature ranges.
7. Troubleshooting
If you encounter issues with your ATS Dual-Power Transfer Switch, refer to the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| Failure to switch power | Loose wiring connections. | Disconnect all power, then check and securely tighten all wiring connections. |
| Switch overheating | Excessive electrical load. | Reduce the connected load to within the switch's rated capacity (63A). Ensure proper ventilation around the device. |
| No power output | No power from either source; switch in "O" position; incorrect wiring. | Verify power supply from both sources. Check selector switch position. Review wiring diagram for correct connections. |
If the problem persists after attempting these solutions, please contact customer support.
