To configure the Socomec ATI 250 A automatic changeover switch for a single-phase network:
1. Voltage Configuration: - Use the split-phase network/single-phase generator configuration. - Ensure the generator supplies two-phase networks feeding single-phase loads.
2. Wiring Adjustment: - Connect power wires from terminals 206 & 103 to terminals 205 & 104. - This provides the required 220/230V or 240V to power inputs 101/102 and 201/202.
3. Loss of Mains Automatic Sequence: - Ensure the switch is in automatic mode. - If mains power is lost, the switch will automatically transfer to the generator. - When mains power returns, the switch will transfer back.
4. Generator Sensing: - The generator sensing circuit is single-phase. - Ensure proper voltage measurement and display settings.
By following these steps, the ATI 250 A can be correctly set up for a single-phase network.

Questions and answers
a place where the mains is supply as a single phase network, how can you configure the settings on automatic changeover switch to suit
To configure the Socomec ATI 250 A automatic changeover switch for a single-phase network:
1. Voltage Configuration:
- Use the split-phase network/single-phase generator configuration.
- Ensure the generator supplies two-phase networks feeding single-phase loads.
2. Wiring Adjustment:
- Connect power wires from terminals 206 & 103 to terminals 205 & 104.
- This provides the required 220/230V or 240V to power inputs 101/102 and 201/202.
3. Loss of Mains Automatic Sequence:
- Ensure the switch is in automatic mode.
- If mains power is lost, the switch will automatically transfer to the generator.
- When mains power returns, the switch will transfer back.
4. Generator Sensing:
- The generator sensing circuit is single-phase.
- Ensure proper voltage measurement and display settings.
By following these steps, the ATI 250 A can be correctly set up for a single-phase network.
