Safety Instructions
This manual contains essential information for the protection of users
and others from possible injury and/or equipment damage.
•Read this manual before using the product, to ensure correct handling,
and read the manuals of related apparatus before use.
•Keep this manual in a safe place for future reference.
•These instructions indicate the level of potential hazard with the labels
of "Caution", "Warning" or "Danger", followed by important safety
information which must be carefully followed.
•To ensure safety of personnel and equipment the safety instructions in
this manual and the product catalogue must be observed, along with
other relevant safety practices.
WARNING indicates a hazard with a medium level
of risk which, if not avoided, could result in death or
serious injury.
DANGER indicates a hazard with a high level of risk
which, if not avoided, will result in death or serious
injury.
CAUTION indicates a hazard with a low level of risk
which, if not avoided, could result in minor or
moderate injury.

Summary of Product element
This product is class A equipment that is intended for use in an industrial
environment.
There may be potential difficulties in ensuring electromagnetic
compatibility in other environments due to conducted as well as radiated
disturbances.
NOTE
•
When conformity to UL is necessary the SI unit must be used with a
UL 1310 Class2 power supply.

•Do not disassemble, modify (including changing the printed circuit
board) or repair.
An injury or failure can result.
•Do not operate the product outside of the specifications.
Do not use for flammable or harmful fluids.
Fire, malfunction, or damage to the product can result.
Verify the specifications before use.
•Do not operate in an atmosphere containing flammable or
explosive gases.
Fire or an explosion can result.
This product is not designed to be explosion proof.
•If using the product in an interlocking circuit:
•
Provide a double interlocking system, for example a mechanical
system.
•
Check the product regularly for proper operation.
Otherwise malfunction can result, causing an accident.
•The following instructions must be followed during maintenance:
•
Turn off the power supply.
•
Stop the air supply, exhaust the residual pressure and verify that the
air is released before performing maintenance.
Otherwise an injury can result.
•After maintenance is complete, perform appropriate functional
inspections.
Stop operation if the equipment does not function properly.
Safety cannot be assured in the case of unexpected malfunction.
•Provide grounding to assure the safety and noise resistance of the
Fieldbus system.
Individual grounding should be provided close to the product with a
short cable.
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.

Tightening torque 0.6 Nm
Valve manifold
∗
: Thread size: M3×30
Replacement of the SI unit
•Remove the M3 hexagon screws from the SI unit and release the
SI unit from the valve manifold.
•Replace the SI unit.
•Tighten the screws with the specified tightening torque. (0.6 Nm)
Precautions for maintenance
•Be sure to switch off the power.
•Check there is no foreign matter inside the SI unit.
•Check there is no damage and no foreign matter being stuck to the
gasket.
•Be sure to tighten the screws with the specified torque.
If the SI unit is not assembled properly, inside PCBs may be damaged or
liquid and/or dust may enter into the unit.
