Installation Guidelines

1. 1 Verify that the control panel or enclosure is fully de-energized and locked out. Use a calibrated multimeter to confirm zero energy state at the intended power connection point.
2. 2 Prepare the panel cutout according to the device's mechanical specifications. Ensure the mounting surface is clean, flat, and free of debris to guarantee a proper seal.
3. 3 Insert the Panel PC into the cutout from the front. Secure it from the rear using the provided mounting clamps, tightening them evenly to the manufacturer's specified torque to avoid warping the bezel.
4. 4 Connect the protective earth (PE) or chassis ground terminal to the enclosure's main ground bus using a low-impedance conductor. This is critical for electrical safety and noise immunity.
5. 5 Connect the AC mains power cable to the unit's power input. Ensure the source voltage matches the 115-230V AC rating. Route power cables separately from low-voltage signal and communication wiring.
6. 6 Connect all required communication and I/O cables. Ensure proper shielding and termination as required by the specific protocol (e.g., Ethernet, serial).
7. 7 After verifying all connections are secure and correct, remove the lockout/tagout devices and re-energize the main panel circuit to power on the Panel PC.
