5.2 Wiring Connections

CAUTION: Ensure all power sources are disconnected and locked out before making any electrical connections.

1. Main Power Input: Connect the utility power lines (A, B, C, N) to the designated 'MAIN POWER' terminals on the ATS.
2. Standby Power Input: Connect the generator power lines (A, B, C, N) to the designated 'STANDBY POWER' terminals on the ATS.
3. Load Output: Connect the electrical load lines (A, B, C, N) to the load output terminals of the ATS.
4. Control Wiring: Connect the generator start/stop control wires to the ATS as per the generator manufacturer's instructions and the ATS wiring diagram (not provided in this manual, refer to product packaging or manufacturer's website).
5. Grounding: Connect the ATS to a reliable earth ground.

After all connections are made, double-check all wiring for correctness and tightness before restoring power.

6. Operating Instructions

The ATS can operate in automatic or manual mode.

6.1 Automatic Mode

1. Ensure both main power and standby generator are connected and ready.
2. Set the selector switch on the control panel to the 'Automatic' position (if available, otherwise ensure 'ON' is selected for automatic operation).
3. When main power fails, the ATS will automatically detect the outage, initiate the generator start sequence, and transfer the load to the generator once stable.
4. When main power is restored, the ATS will automatically transfer the load back to the main power and shut down the generator after a cool-down period.

6.2 Manual Mode

Manual operation allows for direct control over the power source selection.

1. Press the 'Manual' button on the control panel.
2. Use the 'ON' and 'OFF' buttons or the selector switch to manually choose between 'MAIN POWER' and 'STANDBY POWER'.
3. Always ensure the selected power source is stable before transferring the load.

6.3 LED Indicators

Refer to the ATS unit's specific LED indicator legend for detailed status information. Generally, LEDs indicate:

• Power availability (Main/Standby)
• Current power source connected to load
• System status or fault conditions
