Installation Guidelines

1. 1 Panel Cutout: Prepare the control cabinet panel cutout according to the manufacturer's dimensional drawings. Ensure all metal shavings are removed from the enclosure to prevent short circuits.
2. 2 Mounting: Insert the HMI into the cutout from the front of the panel. Secure it evenly using all provided mounting clamps, tightening them to the specified torque to ensure a proper seal (IP rating).
3. 3 Grounding: Connect the functional earth (FE) terminal on the HMI chassis to the main protective earth busbar of the control cabinet using a low-impedance conductor. This is critical for noise immunity and safety.
4. 4 Power Connection: Connect the 24V DC power supply to the designated terminals. Ensure correct polarity. Use a dedicated, regulated power supply unit (PSU) rated for industrial environments.
5. 5 Network Connection: Connect the PROFINET or PROFIBUS cables to the corresponding ports. Use shielded cables and ensure proper shield termination at one end to minimize electromagnetic interference (EMI).
