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.
CAUTION indicates a hazard with a low level of
Caution risk which, if not avoided, could result in minor or
moderate injury.

serious injury.
DANGER indicates a hazard with a high level of
Danger risk which, if not avoided, will result in death or seri-
ous injury.
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.
Warning
• Do not disassemble, modify (including change of printed circuit
board) or repair the product.
An injury or product failure may result.
•
Do not operate the product beyond the specification range.
Fire, malfunction or equipment damage may result. Use the product
only after confirming the specifications.
•
Do not use the product in the presence of flammable, explosive or
corrosive gas.
Fire, explosion or corrosion may result. This product does not have an
explosion proof construction.
• When using the product as part of an interlocking system:
1) Provide a double interlocking system, for example a mechanical
system.
2) Check the product regularly to ensure proper operation.
•
Before performing maintenance, be sure of the following:
1) Turn off the power supply.
2) Stop the air supply, exhaust the residual pressure and verify the
release of air from the system.
Caution
•
Always perform a system check after maintenance.
Do not use the product if any error occurs.
Safety cannot be assured if caused by un-intentional malfunction.
•
Provide grounding to ensure correct operation and to improve
noise resistance of the product.
This product should be individually grounded using a short cable.
• Follow the instructions given below when handling the product.
Failing to do so may result in product damage.
• Maintenance space should always be provided around the product.
• Do not remove labels from the product.
• Do not drop, hit or apply excessive shock to the product.
• Follow all specified tightening torques.
Safety Instructions (continue)
•
Do not bend, apply tensile force, or apply force by placing heavy
loads, on the cables.
•
Connect wires and cables correctly, and do not connect while the
power is ON.
•
Do not route wires and cables together with power or high-voltage
cables.
•
Check the insulation of wires and cables.
• Take proper measures against noise, such as noise filters, when the
product is incorporated in equipment or devices.
• Select the required protection (IP) rating according to the environment
of operation.
• Take sufficient shielding measures when the product is to be used in the
following conditions:
(1) where noise due to static electricity is generated.
(2) where electro-magnetic field strength is high.
(3) where radioactivity is present.
(4) where power lines are located.
• Do not use the product in a place where electric surges are generated.
•
Use suitable surge protection when a surge generating load such as a
solenoid valve are to be directly driven.
•
Prevent any foreign matter from entering this product.
• Do not expose the product to vibration or impact.
•
Use the product within the specified ambient temperature range.
• Do not expose the product to any heat radiation.
•
Use a precision screwdriver with flat blade to adjust the Rotary switch.
• Close the cover over the switches before power is applied.
•
Do not clean the product with chemicals such as benzene or thinners.
NOTE
•When conformity to UL is necessary the SI unit must be used with a UL
1310 Class2 power supply.
