5. Setup and Installation
Before installation, ensure the ATS unit is intact. Use the operating handle to manually turn it on or off to check its flexibility. Verify the generation and disconnection conditions of normal and backup power loads.
5.1 Installation Steps
- Power Disconnection: Crucially, ensure all power to the installation area is completely shut off at the main breaker before beginning any work.
- Mounting: Install the automatic transfer switch onto a standard 35mm DIN rail within a PZ30 distribution box. Ensure it is securely fastened.
- Wiring:
- Connect the normal power supply (Source A) to the designated terminals.
- Connect the backup power supply (Source B) to the designated terminals.
- Connect the load output terminals to your electrical system.
- Connect the control lines as per the wiring diagram.

6. Operating Instructions
The Eujgoov Mini ATS is designed for automatic operation, but also features a manual override.
6.1 Automatic Mode
In automatic mode, the switch will continuously monitor the normal power supply (Source A). If the normal power supply deviates or fails, the switch will automatically transfer the load to the backup power supply (Source B) within milliseconds. Once the normal power supply is restored and stable, the switch will automatically transfer the load back to Source A.
- Ensure the selector switch on the unit is set to "Auto".
- The unit will automatically manage power transfer based on the availability of Source A and Source B.
6.2 Manual Mode
For testing or specific scenarios, the switch can be operated manually.
- Set the selector switch on the unit to "Manual".
- Use the red operating handle to manually switch between "Normal Power A" and "Reverse Power B".
- Caution: Always ensure the load can handle the manual switchover and that power sources are stable before manual operation.
7. Maintenance
Regular maintenance ensures the longevity and reliable operation of your automatic transfer switch. Always disconnect power before performing any maintenance.
- Periodic Inspection: Visually inspect the unit periodically for any signs of damage, loose connections, or overheating.
- Cleaning: Keep the unit clean and free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners.
- Terminal Check: Periodically check all terminal connections to ensure they are tight. Loose connections can lead to overheating and malfunction.
- Functional Test: It is recommended to periodically test the automatic transfer function by simulating a power outage (if safe and feasible) to ensure the switch operates correctly.
8. Troubleshooting
If you encounter issues with your automatic transfer switch, refer to the following common troubleshooting steps. For complex issues, contact a qualified electrician or the manufacturer.
| Problem | Possible Cause | Solution |
|---|---|---|
| Switch does not transfer automatically. | Unit is in manual mode; Normal power source failure not detected; Control wiring issue. | Ensure selector is in "Auto" mode. Verify normal power source is truly off. Check control wiring connections. |
| No power to load after transfer. | Backup power source failure; Loose load connections; Internal fault. | Verify backup power source is active. Check load wiring. If problem persists, consult a professional. |
| Unit feels hot. | Overload; Loose connections; Incorrect wiring. | Immediately disconnect power. Check load current against rated current. Tighten all connections. Verify wiring. |
| Manual switchover is stiff. | Dust/debris; Mechanical issue. | Clean the mechanism. Do not force. If still stiff, do not use manual mode and consult professional. |
