5.1 Wiring Diagram
Follow the wiring diagram carefully. Incorrect wiring can lead to device malfunction or electrical hazards. Use appropriate wire gauges for the rated current.
Figure 5.2: Wiring connections for Main Power, Backup Power, and Load.
- Connect the Main Power (utility) to terminals labeled (I) N1/A1.
- Connect the Backup Power (generator) to terminals labeled (II) N2/A2.
- Connect the Load to the terminals labeled LOAD N|L1 at the bottom of the switch.
- Ensure all connections are tight and secure.
6. Operating Instructions
The ATS switch offers both automatic and manual operation modes.
6.1 Automatic Mode
- Set the Hand/Automatic switch to "AUTO".
- In this mode, the switch will automatically detect the presence of Main Power. If Main Power is available, it will connect the load to Main Power.
- If Main Power fails, the switch will automatically transfer the load to Backup Power (if available).
- When Main Power is restored, the switch will automatically transfer the load back to Main Power.
6.2 Manual Mode
- Set the Hand/Automatic switch to "MANU".
- Use the Operating Switch (lever) to manually select between power source 1 (Main Power) or power source 2 (Backup Power).
- Ensure the desired power source is stable before manually switching.

7. Maintenance
The ATS switch is designed for minimal maintenance. However, regular checks are recommended:
- Periodically inspect all wiring connections for tightness and signs of corrosion.
- Keep the device clean and free from dust and debris.
- Ensure the operating environment remains within the specified temperature and humidity ranges.
- Test the automatic transfer function periodically by simulating a main power outage (e.g., by temporarily disconnecting the main power source, if safe to do so).
8. Troubleshooting
If you encounter issues with your ATS switch, consider the following:
- No Power Transfer: Check if both main and backup power sources are active. Verify all wiring connections are correct and secure. Ensure the switch is in "AUTO" mode for automatic transfer.
- Load Not Receiving Power: Check the "Load ON" indicator. If off, verify power input from both sources and check the operating switch position. Inspect the load wiring.
- Overheating: Ensure the device is not overloaded beyond its rated current (63A). Check for proper ventilation around the unit.
For persistent issues, consult a qualified electrician or contact customer support.
9. User Tips
While this device is designed for automatic operation, understanding its manual functions can be beneficial:
- Familiarize yourself with the manual override switch for situations where you might need to control power transfer directly.
- Consider labeling your power sources clearly at the input terminals for easier identification during installation or troubleshooting.
