What is the procedure for emergency shutdown of the EPP III?

Explanation:
In an emergency shutdown, the aim is to cut power quickly and prevent any re-energizing until it’s verified safe. For the EPP III, removing the key from the Master Switch provides a decisive, physical lockout: the master power cannot be re-enabled without the key. This ensures the entire system stays off and cannot be accidentally or unauthorizedly restarted, which is why this method is the best choice. Turning off the Master Switch without removing the key still allows someone with access to reinsert the key and turn power back on. Disconnecting the battery may not eliminate all power sources in the system and can be impractical or unsafe in an urgent situation. Engaging the Emergency Stop Button often halts a specific function or process but does not guarantee complete de-energization and can be reset without addressing the master power state. So, removing the key from the Master Switch is the most reliable way to secure a full emergency shutdown of the EPP III.
