This section provides basic information on wiring the Power Supply Unit and I/O
Units, and on connecting Peripheral Devices.
The following diagram shows the proper connection to an AC power supply. The
AC voltage should be between 100 and 240 VAC. Refer to 2-2-3 Selecting a
Power Supply Unit for details on Power Supply Unit capacity.
Remove the seal from the top of the Power Supply Unit only after wiring is com-
pleted. This seal must be removed before operating the Unit to prevent over-
heating.
The cross-sectional area of each wire must be 2 mm
Be sure that the AC power supply voltage remains within the allowed fluctuation
range of 85 to 264 VAC.
CQM1-PA216 is switchable with an input voltage range of 80 to 138 VAC or 160
to 264 VAC.
The following diagram shows the terminal blocks for the two AC Power Supply
Units.
