Installation Guidelines

1. De-energization: Ensure all power to the Panel PC and connected systems is disconnected before beginning installation.
2. Mounting: Mount the Panel PC securely into a control cabinet or panel cutout, ensuring proper ventilation and access to ports.
3. Power Connection: Connect the 24 V DC power supply to the designated terminals, observing correct polarity. Verify the power source meets the specified voltage requirements.
4. Grounding: Establish a reliable protective earth (PE) connection to the Panel PC chassis to ensure electrical safety and minimize electromagnetic interference.
5. Ethernet Connections: Connect standard Ethernet cables to the RJ45 ports for network integration.
6. USB and Serial Connections: Connect peripheral devices or external communication modules to the USB and serial (COM1) ports as required.
7. PROFIBUS/MP Connection: If utilizing PROFIBUS/MP, connect the appropriate fieldbus cable to the dedicated interface.
8. Cable Management: Route all cables to prevent strain, interference, and damage, ensuring they do not obstruct cooling airflow.
9. Re-energization: After all connections are secure and verified, restore power to the Panel PC and connected systems.
