The CPU of the C200HS has no I/O points built in. So, in order to complete the
PC it is necessary to mount one or more I/O Units to the Backplane. Mount the
I/O Unit to the Backplane by locking the top of the I/O Unit into the slot on the
Backplane and rotating the I/O Unit downwards as shown in the following dia-
gram.

Press down on the yellow lock lever at the bottom of the slot, press the I/O Unit
firmly into position, and then release the yellow lock lever.
(To remove a Unit, hold down the lock lever with an implement such as a screw-
driver.)
