Mounting/Installation (continued )
Layout of the Input Block
Position the Input Block on the left side of the SI Unit.
Layout of the EX9 series Output Block / Power Block
Position the Output Block / Power Block on the right side of the SI Unit and between
the SI Unit and solenoid valve or End Plate R (on the Output Block side).
1) Output Block for high wattage load
The Output Block for high wattage load cannot be used independently.
Be sure to combine with the Power Block for use.
2) Position of Output Block for high wattage load
The Output Block for high wattage load cannot be mounted at the place nearer to
the SI Unit than the Power Block. However, that place is acceptable if the Power
Block is located between SI Unit and the Output Block for high wattage load.
3) Output Block for low wattage load
The Output Block for low wattage load cannot be mounted at the right side of the
Power Block. Mount to the place nearer to the SI Unit than the Power Block.
Position of End Plate
Be sure to connect the End Plate (on the Input Block side) at the left end of the
manifold.
When the valve is not connected, be sure to connect the End Plate R (on the
Output Block side) at the right end of the manifold.

[mm]
* Each dimension shows the unit without solenoid valves connected and with an End Plate
R (on the Output Block side) connected. Standard settings of L dimensions are with 10
or less m blocks. Ask SMC sales for the setting with over 10 blocks mounted.
Refer to the individual specifications for the dimensions when the solenoid valves are
connected.
Wiring (power supply, communication, input/output) and piping are all in one direction.
Space for wiring and piping is required in that direction.
