Installation Guidelines

1. 1 Prepare Panel Cutout: Ensure the mounting cutout in the enclosure or panel matches the dimensions specified for the PC 677B. Verify that the mounting surface is clean, flat, and free of debris.
2. 2 Mount the Unit: 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 recommended torque to ensure a proper seal.
3. 3 Establish Ground Connection: Connect the chassis ground terminal on the Panel PC to the main protective earth (PE) busbar of the enclosure using a low-impedance grounding conductor. This is critical for safety and noise immunity.
4. 4 Connect Power Supply: Connect a stable, correctly rated 24 V DC power source to the power input terminals. Ensure correct polarity is observed. Use appropriately sized wiring for the current draw.
5. 5 Connect Peripherals and Networks: Connect Ethernet, PROFIBUS, USB, and serial cables as required by the application. Ensure all cables are properly shielded and routed away from high-voltage lines to prevent interference.
