Installation Guidelines

1. 1 Inspect the Panel PC for any signs of shipping damage. Do not install if damage is apparent. Verify the model number matches the order specifications.
2. 2 Prepare the panel cutout according to the device's mechanical drawings. Ensure sufficient clearance around the unit for ventilation and cable routing, especially at the rear.
3. 3 Mount the Panel PC securely into the cutout using all provided mounting clamps. Tighten clamps evenly to ensure a proper seal against the panel surface.
4. 4 Connect a reliable chassis ground to the designated grounding terminal on the Panel PC. A low-impedance ground connection is critical for noise immunity and safety.
5. 5 Connect the 24V DC power supply. Verify correct polarity (+/-) before energizing the circuit. Use appropriately sized wiring for the current draw and secure connections at the terminal block.
6. 6 Connect all required communication and peripheral cables (e.g., Ethernet, USB). Route cables away from high-voltage lines to prevent electrical noise interference. Power on the unit and verify correct system boot-up.
