Installation Guidelines

1. 1 Panel Mounting: Prepare the control cabinet cutout according to the manufacturer's dimensional drawings. Ensure the mounting surface is clean, flat, and rigid. Install the Panel PC using all provided mounting clamps and tighten them evenly to the specified torque to ensure a proper seal (IP rating).
2. 2 Power Connection: Connect a stable, filtered 24V DC power source to the designated power terminals. Use appropriately sized conductors for the load and distance. Ensure correct polarity is observed. The power supply should be a Safety Extra-Low Voltage (SELV) or Protective Extra-Low Voltage (PELV) type.
3. 3 Protective Earth (PE) Grounding: Connect the chassis grounding terminal to the main protective earth bus bar of the control cabinet using a low-impedance conductor. A reliable ground connection is critical for operator safety and electromagnetic compatibility (EMC).
4. 4 Ventilation and Clearance: Ensure adequate ventilation around the unit's heat sink and vents. Maintain the minimum clearance distances specified by the manufacturer on all sides to prevent overheating and ensure reliable operation. Do not block airflow with cables or other components.
