equipment. Only those persons are allowed to perform assembly, operation and maintenance.
Read and understand this operation manual carefully before assembling, operating or providing
maintenance to the product.
■Safety Instructions
Warning
•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.
Caution
•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.

■NOTE
○Follow the instructions given below when designing, selecting and handling the product.
The instructions on design and selection
(installation, wiring, environment, adjustment, operation,
maintenance, etc.)
described below must also be followed.
Product specifications
•When conformity to UL is required, the SI unit should be used with a UL1310 Class 2 power supply.
The SI unit is a UL approved product only if it has a UL mark on the body.
•Use the specified voltage.
Otherwise failure or malfunction can result.
•Reserve a space for maintenance.
Allow sufficient space for maintenance when designing the system.
•Do not remove any nameplates or labels.
This can lead to incorrect maintenance, or misreading of the operation manual, which could cause damage or
malfunction to the product.
It may also result in non-conformity to safety standards.

Product handling
Installation
•Do not drop, hit or apply excessive shock to the SI unit.
Otherwise damage to the product can result, causing malfunction.
•Tighten to the specified tightening torque.
If the tightening torque is exceeded the mounting screws may be broken.
IP67 protection cannot be guaranteed if the screws are not tightened to the specified torque.
•Never mount a product in a location that will be used as a foothold.
The product may be damaged if excessive force is applied by stepping or climbing onto it.
Wiring
•Avoid repeatedly bending or stretching the cables, or placing heavy load on them.
Repetitive bending stress or tensile stress can cause breakage of the cable.
•Wire correctly.
Incorrect wiring can break the product.
•Do not perform wiring while the power is on.
Otherwise damage to the SI unit and/or I/O device can result, causing malfunction.
•Do not route wires and cables together with power or high voltage cables.
Otherwise the SI unit and/or I/O device can malfunction due to interference of noise and surge voltage from power
and high voltage cables to the signal line.
Route the wires (piping) of the SI unit and/or I/O device separately from power or high voltage cables.
•Confirm proper insulation of wiring.
Poor insulation (interference from another circuit, poor insulation between terminals, etc.) can lead to excess
voltage or current being applied to the product, causing damage.
•Take appropriate measures against noise, such as using a noise filter, when the SI unit is incorporated
into equipment.
Otherwise noise can cause malfunction.
Environment
•Select the proper type of protection according to the environment of operation.
IP67 protection is achieved when the following conditions are met.
(1) The units are connected properly with fieldbus cable with M12 connector and power cable with M12/M8 connector.
(2) Suitable mounting of each unit and manifold valve.
If using in an environment that is exposed to water splashes, please take measures such as using a cover.
•Do not use in a place where the product could be splashed by oil or chemicals.
If the product is to be used in an environment containing oils or chemicals such as coolant or cleaning solvent,
even for a short time, it may be adversely affected (damage, malfunction etc.).
•Do not use the product in an environment where corrosive gases or fluids could be splashed.
Otherwise damage to the product and malfunction can result.
•Do not use in an area where surges are generated.
If there is equipment which generates a large amount of surge (solenoid type lifter, high frequency induction
furnace, motor, etc.) close to the SI unit, this may cause deterioration or breakage of the internal circuit of the SI
unit. Avoid sources of surge generation and crossed lines.
•When a surge-generating load such as a relay or solenoid is driven directly, use an SI unit with a built-in
surge absorbing element.
Direct drive of a load generating surge voltage can damage the SI unit.
•The product is CE marked, but not immune to lightning strikes. Take measures against lightning strikes
in the system.
•Prevent foreign matter such as remnant of wires from entering the SI unit to avoid failure and malfunction.
Otherwise failure or malfunction can result.

Otherwise failure or malfunction can result.
•Do not use the product in an environment that is exposed to temperature cycle.
Heat cycles other than ordinary changes in temperature can adversely affect the inside of the product.
•Do not expose the product to direct sunlight.
If using in a location directly exposed to sunlight, shade the product from the sunlight.
Otherwise failure or malfunction can result.
•Keep within the specified ambient temperature range.
Otherwise malfunction can result.
•Do not operate close to a heat source, or in a location exposed to radiant heat.
Otherwise malfunction can result.

It may damage set switches.
•Perform settings suitable for the operating conditions.
Incorrect setting can cause operation failure.
For details of each setting, refer to page 15 of this manual.
•Please refer to the PLC manufacturer's manual etc. for details of programming and addresses.
For the PLC protocol and programming refer to the relevant manufacturer's documentation.
Maintenance
•Turn off the power supply, stop the supplied air, exhaust the residual pressure and verify the release of
air before performing maintenance.
There is a risk of unexpected malfunction.
•Perform regular maintenance and inspections.
There is a risk of unexpected malfunction.
•After maintenance is complete, perform appropriate functional inspections.
Stop operation if the equipment does not function properly.
Otherwise safety is not assured due to an unexpected malfunction or incorrect operation.
• Do not use solvents such as benzene, thinner etc. to clean the SI unit.
They could damage the surface of the body and erase the markings on the body.
Use a soft cloth to remove stains.
For heavy stains, use a cloth soaked with diluted neutral detergent and fully squeezed, then wipe up the stains
again with a dry cloth.
