4. Installation
4.1 Mounting
The ATS switch is designed for panel mounting. Ensure sufficient space for wiring and ventilation.
4.2 Wiring Diagram
Refer to the following diagram for correct wiring connections. Ensure all connections are tight and secure.
Wiring Steps:
- Connect the Normal Power live line to the "N" live terminal and the Normal Power neutral line to the "N" neutral terminal.
- Connect the Emergency Power live line to the "R" live terminal and the Emergency Power neutral line to the "R" neutral terminal.
- Connect the Load live line to the output live terminal and the Load neutral line to the output neutral terminal.
- Ensure proper grounding for all connected circuits.
Important Note from Product Label:
The label indicates specific instructions for normal and reserve power off conditions, particularly for 220V systems. Always refer to the detailed label on your specific unit for precise wiring and operational details.
5. Operation
5.1 Automatic Mode
In Automatic mode, the switch will automatically transfer the load between the Normal Power Supply and the Backup Power Supply based on their availability.
- Set the mode selector switch to "Automatic".
- When Normal Power is present, the switch will connect to it. The "Normal Power Supply" and "Normal Closing" indicators will illuminate.
- If Normal Power fails, the switch will automatically transfer to the Backup Power Supply (if available). The "Backup Power Supply" and "Backup Closing" indicators will illuminate.
- When Normal Power is restored, the switch will automatically transfer back to Normal Power (if configured for automatic retransfer).
5.2 Manual Mode
In Manual mode, you can manually switch between power sources using the operating handle.
- Set the mode selector switch to "Manual".
- To connect to Normal Power, rotate the handle towards the "N" side.
- To connect to Emergency Power, rotate the handle towards the "R" side.
- To disconnect from both power sources, rotate the handle to the central "0" position.
- Always ensure the handle is fully engaged in the desired position.
6. Maintenance
- Regularly inspect the switch for any signs of damage, loose connections, or overheating.
- Keep the switch clean and free from dust and debris. Use a dry cloth for cleaning.
- Do not use abrasive cleaners or solvents.
- Periodically check terminal screws for tightness.
- Ensure proper ventilation around the switch.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Switch does not transfer power. | No power from either source; incorrect wiring; switch in manual mode. | Check power sources; verify wiring according to diagram; ensure switch is in "Automatic" mode for automatic transfer. |
| Indicator lights are off. | No power to the switch; faulty indicator. | Check incoming power; contact support if power is present but indicators remain off. |
| Switch makes unusual noises or smells. | Overload; loose connection; internal fault. | Immediately disconnect power. Do not operate. Contact qualified electrician or support. |

9. User Tips
- Understanding "2P" and "4P": "2P" refers to a 2-pole switch, typically used for single-phase systems where both the live and neutral lines are switched. "4P" refers to a 4-pole switch, commonly used in three-phase systems where all three live phases and the neutral line are switched. Ensure you select the correct pole configuration for your electrical system.
- Always double-check the voltage and current ratings of your power sources and load to ensure compatibility with the ATS switch.
- For critical applications, consider having a qualified electrician perform the installation and initial setup.
