The following diagram shows a CQM1H PC consisting of a Power Supply
Unit, Communications Unit, CPU Unit, and I/O Units. Be sure to connect an
End Cover to the right side of the Unit on the opposite end of the PC from the
CPU Unit.

The following table lists the total width, W, of the PC.
n = No. of I/O Units + No. of Dedicated I/O Units.
Note For example, if a CQM1-CPU51/61 Power Supply Unit is used and there is a
total of four I/O Units and Dedicated I/O Units, the width would be 347 mm.
W = 32
× 4 + 219 = 347 mm
If a Communications Unit is connected to the CQM1-CPU51/61, add 32 mm
to obtain the total width.
