To reassemble the device, proceed as follows:
Carefully insert the boards into the case. The installation locations of the boards are
shown in Figure 8-8 to 8-10.
For the model of the device designed for surface mounting, use the metal lever to
insert the processor circuit board C-CPU-2 board. The installation is easier with the
lever.
First plug the plug connectors of the ribbon cable into the input/output boards I/O and
then onto the processor module C-CPU-2. Be careful to not bend any of the
connecting pins! Do not use force!
Insert the plug connector of the ribbon cable between the processor module
C-CPU-2 and the front cover into the socket of the front cover.
For the version with detached operator panel the latter is to be ignored. Instead the
plug connector of the ribbon cable connected to a 68pole plug connector on the rear
side of the device must be plugged into the plug connector of the processor circuit
board C-CPU-2. The 7-pole plug connector X16 connected to the ribbon cable must
be plugged behind the D-subminiature female connector. Since the connection is
protected against polarity reversal, no particular plug-in position must be observed.
Press the latches of the plug connectors together.
Replace the front cover and secure to the housing with the screws.
Replace the covers.
Re-fasten the interfaces on the rear of the device housing.
This activity is not necessary if the device is designed for surface mounting.
