Installation Guidelines

1. 1
   Panel Cutout and Mounting: Prepare the control cabinet panel cutout according to the device's mechanical drawings. Ensure the mounting surface is clean, flat, and rigid. Insert the Panel PC into the cutout from the front and secure it evenly from the rear using all provided mounting clamps. Do not overtighten the clamps.
2. 2
   Protective Earth (PE) Connection: Connect the chassis grounding terminal to the control cabinet's main protective earth busbar using a low-impedance conductor. This connection is critical for operator safety and electromagnetic compatibility (EMC).
3. 3
   Power Supply Connection: Connect a stable, filtered 24V DC power source to the designated power input terminals. Verify correct polarity (+/-) before energizing the circuit. Use appropriately sized wiring and ensure the power supply is adequately rated for the PC's load.
4. 4
   Ventilation and Clearance: Ensure adequate clearance around the rear of the unit for heat dissipation. Do not block ventilation openings. Verify that the ambient operating temperature inside the cabinet remains within the specified limits to prevent overheating.
5. 5
   Interface Cabling: Connect all required communication and I/O cables. Route cables to avoid interference from high-voltage lines and ensure proper strain relief. Use shielded cables for all data communication lines and connect shields to ground as specified.
