Installation Guidelines

1. 1
   De-energize the entire control cabinet and verify the absence of voltage before beginning installation. Apply appropriate LOTO devices.
2. 2
   Prepare the panel cutout according to the manufacturer's dimensional drawings. Ensure the mounting surface is clean, flat, and free of debris.
3. 3
   Insert the Panel PC into the cutout from the front. Secure it from the rear using all provided mounting clamps, tightening them evenly to the specified torque to ensure a proper seal.
4. 4
   Connect the Protective Earth (PE) terminal to the cabinet's main ground bus using a low-impedance conductor of the appropriate gauge. This is critical for safety and noise immunity.
5. 5
   Connect the 110/230 V AC power supply cable to a properly rated and protected power source.
6. 6
   Connect all required communication cables, such as Ethernet and PROFIBUS. Ensure proper shielding and grounding practices are followed for all data cables.
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.
