Installation Guidelines

1. 1
   Pre-Installation Inspection: Visually inspect the Mobile Panel for any signs of shipping damage. Verify the model number 6AV6645-0CB01-0AX0 matches the project requirements. Ensure the connection cable is undamaged and correct for the application.
2. 2
   Connecting the Panel: With the system de-energized, connect the system cable to the Mobile Panel and the corresponding connection box or controller interface. Ensure connectors are fully seated and locked. Provide adequate strain relief for the cable to prevent stress on the connectors during movement.
3. 3
   Power Application: After verifying all connections, remove the LOTO and apply power to the system. The Mobile Panel requires a stable, regulated 24V DC SELV/PELV power source. Observe the panel for a successful boot sequence.
4. 4
   Project Download: Connect the programming device and download the configured HMI project from TIA Portal or WinCC flexible. Confirm successful transfer and that the correct application screen is displayed.
5. 5
   Functional Safety Test: Before enabling machine operation, perform a thorough functional test in a safe, controlled state. Verify communication with the PLC, test all screen objects, and critically, test the functionality of the stop pushbutton and acknowledgment button to ensure they perform as required by the system's safety risk assessment.
