Tighten the screws on the terminal block of the AC Power Supply Unit to the torque specified in the operation manual. The loose screws may result in burning or malfunction. Always turn OFF the power supply to the PC before attempting any of the following. Performing any of the following with the power supply turned ON may lead to electrical shock:
· Mounting or removing any Units (e.g., I/O Units, CPU Unit, etc.) or memory cassettes.
· Assembling any devices or racks.
Take measures to stabilize the power supply to conform to the rated supply if it is not stable. Provide reinforced insulation or double insulation for the DC power source connected to the DC I/O Unit and for the Power Supply Unit. Use a separate power source for the DC I/O Unit from the external power supply for the Relay Output Unit.


An Expansion I/O Rack can be thought of as an extension of the PC because it provides additional slots to which other Units can be mounted. It is built onto an Expansion I/O Backplane to which a Power Supply and up to ten other Units are mounted.

RUN mode is the mode used for normal program execution. When the switch is set to RUN and the START input on the CPU Power Supply Unit is ON, the CPU Unit will begin executing the program according to the program written in its Program Memory. Although monitoring PC operation from the Programming Console is possible in RUN mode, no data in any of the memory areas can be input or changed.
