3.1.2.5 Reassembly
The device is assembled in the following steps:
• Carefully insert the boards into the case. The mounting locations are shown in figure 3-3. For the model of
the device designed for surface mounting, use the metal lever to insert the processor circuit board A-CPU.
The installation is easier with the lever.
• First, plug the plug connector of the ribbon cable onto the input/output board I/O and then onto the A-CPU
processor board. Do not bend any connector pins! Do not use force!
• Insert the plug connector of the ribbon cable between the processor board A-CPU and the front cover in the
socket on the front cover.
• Press the latches of the plug connectors together.
• Replace the front cover and secure to the housing with the screws.
• Mount the covers again.
• Re-fasten the interfaces on the rear of the device housing. This activity is not necessary if the device is de-
signed for surface mounting.
