Installation Guidelines

1. 1
   De-energize Equipment: Before installation, disconnect all power sources to the control cabinet. Follow all applicable Lockout/Tagout (LOTO) procedures to prevent accidental energization.
2. 2
   Panel Mounting: Ensure the panel cutout dimensions are correct for the MP 377 12" chassis. Insert the HMI into the cutout from the front and secure it evenly using all provided mounting clamps. Do not overtighten the clamps, as this can warp the bezel and damage the display.
3. 3
   Protective Earth (PE) Connection: Connect the functional earth terminal on the HMI chassis to the control cabinet's main protective earth bus using a short, low-impedance conductor. A secure ground connection is essential for noise immunity and safety.
4. 4
   Power Supply Connection: Connect the 24V DC power supply to the designated terminals on the rear of the HMI. Verify correct polarity (+/-) before applying power. Use a dedicated, regulated power supply for optimal performance.
5. 5
   Commissioning: After all connections are secure, remove LOTO devices and re-energize the cabinet. Verify the HMI powers on and loads the correct application project. Test all screen functions and communication links before returning the machine to service.
