Caution
•To prevent damage, all power for the SI Unit and modules must be turned
off (i.e. de-energized) before the modules are installed or removed.
•For a protection rating of IP65 to be ensured, sockets which are not used
must be closed with M12 covering caps.
•For a protection rating of IP65 to be ensured, all covering caps must be
screwed down correctly after all wiring and settings have been completed.

this manual and the product catalogue must be observed, along with
other relevant safety practices.
Operator error could result in serious injury or loss
of life.
In extreme conditions, there is a possibility of
serious injury or loss of life.
Operator error could result in injury or equipment
damage.
•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
SI unit.
Individual grounding should be provided close to the product with a
short cable.
Warning
•Do not disassemble, modify (including changing of 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.
