SAFETY ( continued )
Follow the instructions given below when handling your reduced wiring system.
Otherwise a damage or failure to cause a malfunction can result.
Operate the reduced wiring system at the specified voltage.
Reserve space for maintenance.
Do not remove any name plate or label.
Do not drop, hit or apply an excessive shock to the unit.
Follow the specified tightening torque.
Do not apply any excessive force to cables by repeated bending, tensioning or placing a
heavy object on the cables.
Connect wires and cables correctly.
Do not perform any wiring work while the power is on.
Do not use the reduced wiring system on the same wiring route as the power line or high
voltage line.
Confirm the insulation of wiring.
Perform the power supply wiring by dividing into two lines ---- one is for power supply for output
and the other is for power supply for input and controlling.
Take sufficient measures against noise such as noise filter when incorporating the reduced
wiring system into a machine or equipment.
Mount a Waterproof Cap on each unused M12 connector for input/output.
Take sufficient shielding measures when operating the product in any of the following places.
( 1 ) A place where noise due to static electricity etc. is generated
( 2 ) A place of high electric field strength
( 3 ) A place where exposure to radioactivity is possible
( 4 ) A place near power cable
Do not operate the product in a place where there is a source of surge.
Use a surge absorbing element built-in type to directly drive the load that generates surge
voltage such as solenoid valve.
Prevent any foreign matter such as remnant of wires from getting inside the product when
opening the station number switch protective cover.
Install the reduced wiring system in a place free from vibration and impact.
Operate the product in the specified ambient temperature range.
Do not use in a place to be affected by the radiant heat from a surrounding heat source.
Set the DIP switch by using a sharp-pointed watchmakers screwdriver etc.
Perform the maintenance regularly.
Conduct an appropriate functional inspection after completing the maintenance.
Do not use chemicals such as benzin and thinner to clean the product.

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.

*1 : Remote control (SW1 Dip Switches 1 to 4 off)
SMC's EX250 SI Unit will respond to the following Rockwell Automation BOOTP/DHCP
Server commands.
Enable DHCP
Selecting this function will enable the EX250 SI Unit to retrieve its boot information from
the BOOTP/DHCP Server. If DHCP is enabled the EX250 SI Unit will retrieve its boot
information during the next power up.
Disable BOOTP/DHCP
Selecting this function will disable the EX250 to retrieve its boot information from the
BOOTP/DHCP Server, and causes the EX250 to retain its current configuration during
the next power up.
*2 : DHCP Mode (SW1 Dip Switches 1 to 4 on)
The IP address is acquired via DHCP Server. The IP address is not saved and lost if the
power to the EX250 unit is cycled.
*3 : Hardware Addressing
The IP address range is 192.168.0.1-192.168.0.14.
Default settings
At the time of factory shipment, the product is in "Remote Control Mode" and set to
"Enable DHCP".
Switch setting
Open the switch protective cover and set the switches with a
sharp-pointed watchmakers screwdriver etc.
NOTE
1. Be sure to turn off the power before setting the switches.
2. Be sure to set these switches before use.
3. After setting the switch, close the switch protective cover and tighten the screws
with the proper tightening torque. (Tightening torque : 0.6N m)

Display
The EX9 series General Purpose Output Block is the unit to operate various output
(solenoid valve, relay, etc.) in combination with valve and SI Unit.
There are two types ---- one type is for low wattage load (EX9-OET1) receiving power
supply from SI Unit, and the other type is for high wattage load (EX9-OEP1) receiving
power supply from an external source.
NOTE)
The type for high wattage load is used in combination with the Power Block (EX9-PE1)
connected with external power supply.
As the low wattage load type is powered from SI Unit, the wattage of load is limited to
1.5W
NOTE)
. For a load up to 12W, use the Power Block and the high wattage load type.
