Pushing the E-Stop (Emergency Stop Switch)

The Emergency Stop (E-Stop) is a hardwired, manual shutdown mechanism that provides immediate isolation of the AES Cabinet battery system in the event of an emergency or unsafe operating condition.

The E-Stop is mounted on the exterior of the cabinet for easy access by operators or emergency responders.

1. Press the E-Stop button to cut off power to the Battery Control Unit (BCU) and open all contactors, including those within the battery packs and high-voltage box.

   • This action results in a complete shutdown of all charging, discharging, and thermal management operations.

2. The system remains in a latched-off state until the E-Stop is manually reset and commissioning procedures are followed.

3. To deactivate or turn system back on rotate following the direction arrows on the red E-stop button.

The E-Stop function is independent of software or inverter control and is considered a critical first-response tool in situations involving smoke, overheating, fire risk, or system malfunction. It also satisfies safety compliance requirements in accordance with industrial battery system standards.
