Installation Guidelines

1. 1 De-energize Equipment

   Ensure the main power supply to the installation panel or cabinet is completely shut off and locked out before beginning installation.

2. 2 Prepare Panel Cutout

   Verify the panel cutout dimensions match the requirements for the Panel PC 677B. Ensure the mounting surface is clean, flat, and free of debris.

3. 3 Mount the Unit

   Insert the Panel PC into the cutout from the front. Secure it from the rear using the provided mounting clamps, tightening them evenly to the specified torque to ensure a proper seal.

4. 4 Connect Protective Earth

   Connect the protective earth (PE) terminal on the unit to the cabinet's main ground point using a low-impedance conductor. This connection is critical for safety and noise immunity and must be made first.

5. 5 Connect Power and I/O

   Connect the 110/230V AC power supply cable. Connect Ethernet, PROFIBUS/MPI, USB, and serial cables as required by the application. Ensure proper cable routing and strain relief.

6. 6 Final Checks and Power-Up

   After all connections are secure, remove LOTO devices and restore power to the cabinet. Verify that the Panel PC boots correctly into the Windows operating system.
