Steps for component replacement system
Replacing the frame
1. Cut off the AC power supply; If equipped with a programmer, unplug the programmer.
2. Remove the plastic cover from the wiring terminal board at the right end of the frame and remove the power wiring.
3. Unplug all I/O modules. If there were multiple working circuits during installation, do not mess up the IU/O wiring and note the position of each module in the frame, so as not to make mistakes when reinstalling.
4. If the CPU framework is used, remove the CPU components and filler modules. Place it in a safe place for future reinstallation.
5. Remove the screws securing the bottom two frames and loosen the upper two screws, but do not remove them.

If the module is inserted in the wrong position, it will cause dangerous or incorrect operation of the control system, but it will not damage the module.
10. Insert the removed CPU and filler module.
11. Reconnect the power wiring to the wiring terminal on the right side of the frame, and then cover the plastic cover of the power wiring terminal.

5. Firstly, align the printed circuit board with the bottom guide slot. Insert the new CPU module into the bottom guide slot.
6. Gently shake the CPU module to align it with the top guide slot.
7. Insert the CPU module into the frame until the two elastic locks snap into the slots.
8. Plug in the programmer again and power it on.
