Installation Guidelines

1. 1 Verify that the panel cutout dimensions match the HMI's physical requirements. Ensure the mounting surface is clean, flat, and free of debris.
2. 2 Insert the HMI into the panel cutout from the front. Ensure the gasket provides a uniform seal against the enclosure surface to maintain the IP rating.
3. 3 From the rear, install all mounting clamps provided with the unit. Tighten the clamp screws sequentially and evenly to the manufacturer's specified torque to prevent warping the bezel.
4. 4 Connect the functional earth (ground) terminal on the HMI to the control cabinet's main ground point using a low-impedance conductor.
5. 5 Connect the DC power supply cable to the power terminal block, observing correct polarity. Connect communication cables (e.g., PROFIBUS, Ethernet) to their respective ports.
6. 6 After verifying all connections, remove the lockout/tagout device and re-energize the cabinet to commission the HMI panel.
