Installation Guidelines

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 and secure it evenly using all provided mounting clamps to maintain the specified ingress protection rating.
2. Protective Earth (PE) Connection: Connect the chassis ground terminal to the control cabinet's protective earth bus bar using a low-impedance conductor. This connection is critical for operator safety and electromagnetic compatibility (EMC).
3. Power Connection: After confirming the supply voltage matches the unit's rating (115-230V AC), connect the mains cable to a properly fused and protected power source. Ensure the power cable is routed away from high-noise sources like VFDs or large contactors.
4. Peripheral and Network Cabling: Connect all required peripheral devices (keyboard, mouse) and network cables. Use shielded cables for all data communication lines and ensure shields are properly terminated to ground at one end to minimize electrical noise interference.
