Installation
General instructions on installation and maintenance
Connect valve manifold to the SI unit.
Connectable valve manifolds are the same as for EX250 series SI unit.
Refer to the EX250 series valve manifold section in the valve catalogue for valve
manifold dimensions.
M3 hexagon screw
Tightening torque: 0.6 Nm
Tie rod
Tightening torque: 0.6 Nm
End plate SI unit Valve manihold
Addition of input block
•Remove the screws from the end plate to remove the plate.
•Mount the additional tie rods (supplied with the input block).
•Connect additional input block.
•Re-mount the end plate that was removed, and tighten the screws to the specified
tightening torque. (0.6 m)
Replacing the SI unit
•Remove the screws from the end plate and release the connection with the valve unit.
•Replace the SI unit. (There is no need to remove the tie rod.)
•Re-mount the input block and end plate that was removed, and tighten the screws to
the specified tightening torque. (0.6 m)
Precautions for maintenance
(1)Turn off the power supply completely.
(2)Check that there is no foreign matter inside the unit.
(3)Check that there is no damage and no foreign matter on the gasket.
(4)Tighten the screws to the specified torque.
If the unit is not assembled correctly, this may cause product failure due to foreign
matter such as liquid and dust which may get into the unit.
Connecting cables
Select the appropriate cables to mate with the connectors mounted on the SI unit.
