Installation Guidelines

1. Safety First: Ensure all power to the installation area is de-energized before beginning any work. Follow all local safety regulations and lockout/tagout procedures.
2. Mounting: Securely mount the Panel PC into a suitable control cabinet or panel cutout. Ensure adequate space for ventilation and cable routing.
3. Power Connection: Connect the 110/230 V AC power supply to the designated terminals. Verify correct voltage and polarity before applying power.
4. Grounding: Establish a proper protective earth (PE) connection to the chassis of the Panel PC to ensure electrical safety and minimize electromagnetic interference.
5. Ethernet Connections: Connect industrial Ethernet cables to the 10/100/1000 Mbit/s Ethernet ports for network communication.
6. USB and Serial Connections: Connect peripheral devices (e.g., keyboard, mouse, barcode scanner) to the USB ports and any serial devices to the COM1 port as required.
7. PROFIBUS/MP Connection: If utilizing PROFIBUS/MP, connect the appropriate bus cable to the designated interface, ensuring correct termination.
8. Cable Routing: Route all cables to prevent strain, interference, and damage. Use cable ties and conduits where necessary.
9. Initial Power-Up: After all connections are verified, apply power to the Panel PC. Monitor for proper boot-up and system status.
