Installation Guidelines

1. 1 Verify the panel cutout dimensions are correct for the OP77B housing. Ensure the mounting surface is clean, flat, and free of debris.
2. 2 Insert the operator panel into the prepared cutout from the front of the enclosure.
3. 3 From the rear, install the mounting clips into the designated slots on the HMI housing. Tighten the clips evenly to secure the panel against the enclosure gasket, ensuring a proper seal. Do not overtighten.
4. 4 Connect the 24V DC power supply to the designated terminals, verifying correct polarity. Use appropriate wire gauges for the load and distance.
5. 5 Connect the MPI/PROFIBUS-DP communication cable to the corresponding port. Ensure the cable shield is properly terminated at one end to prevent ground loops.
6. 6 After all connections are verified, remove LOTO devices and re-energize the control panel to begin configuration and commissioning.
