Installation Guidelines

1. De-energization: Ensure all power to the installation area is disconnected and locked out before beginning any work.
2. Mounting: Securely mount the panel PC into a suitable panel cutout or enclosure, ensuring adequate clearance for ventilation and cable routing.
3. Power Connection: Connect the 110/230 V AC power supply cable to the designated power input terminal. Verify correct voltage and grounding.
4. Grounding: Establish a proper protective earth (PE) connection to the panel PC chassis to ensure safety and minimize electromagnetic interference.
5. Interface Connections: Connect Ethernet cables to the RJ45 ports, USB devices to the USB ports, and serial devices to the COM1 port as required by the application. Ensure proper cable routing to prevent strain and interference.
6. PROFIBUS/MP Connection: If utilizing PROFIBUS/MP, connect the appropriate bus cable to the designated interface, observing correct termination and shielding practices.
7. Ventilation: Ensure that the panel PC's ventilation openings are not obstructed to maintain proper operating temperature and prevent overheating.
8. Power Up: After all connections are verified, re-energize the system and observe for proper boot-up and operation.
