Installation Guidelines

1. 1 De-energize the control cabinet and implement lock-out/tag-out (LOTO) procedures before beginning installation.
2. 2 Verify the panel cutout dimensions match the Panel PC's mounting requirements. Ensure the mounting surface is clean, flat, and free of debris.
3. 3 Insert the Panel PC into the cutout and secure it evenly using all provided mounting clamps. Do not over-tighten the clamps to avoid deforming the bezel.
4. 4 Connect a dedicated protective earth (PE) or functional ground wire to the chassis grounding terminal. A low-impedance ground connection is essential for noise immunity and safety.
5. 5 Connect the 24 V DC power supply, ensuring correct polarity is observed. Use appropriately sized conductors for the load and distance from the power supply.
6. 6 Connect Ethernet, PROFIBUS, USB, and any other required communication or peripheral cables. Route cables to minimize strain and avoid interference from high-power lines.
7. 7 After verifying all connections, remove LOTO devices and re-energize the cabinet. Power on the Panel PC and confirm that the operating system boots correctly.
