Installation Guidelines

1. De-energize System: Ensure all power to the control cabinet or system is disconnected before beginning installation.
2. Mounting: Secure the Panel PC into the designated panel cutout or mounting frame according to the system's mechanical specifications. Ensure adequate ventilation space around the unit.
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 and current requirements.
4. Grounding: Establish a proper protective earth (PE) connection to the Panel PC chassis to ensure electrical safety and minimize electromagnetic interference.
5. Ethernet Connections: Connect Ethernet cables to the RJ45 ports for network communication. Use shielded cables in industrial environments to reduce noise.
6. USB and Serial Connections: Connect peripheral devices (e.g., keyboard, mouse, barcode scanner, external serial devices) to the appropriate USB V2.0 and COM1 ports.
7. PROFIBUS/MP Connection: If utilizing PROFIBUS/MP, connect the bus cable to the designated interface. Ensure proper termination of the bus segment.
8. Cable Management: Route all cables to prevent strain, interference, and damage. Secure cables with appropriate ties or conduits.
9. Re-energize and Test: After all connections are made and verified, re-apply power to the system and perform functional tests to ensure proper operation of the Panel PC and connected peripherals.
