IMPORTANT INFORMATION and CAUTION
【CAUTION】
These products (pressure sensors, pressure switches, pressure gauges, pressure indicators, leakage sensors, etc.) are designed and manufactured as general
industrial parts. Therefore, a person with sufficient knowledge and experience shall confirm the conditions and environments described in the catalog, specifications,
and instruction manual of each product, check the suitability of the product for the machine, device, or system which you use, and ensure safety before use.
These products are not intended to be used for applications particularly requiring high reliability (These include, but are not limited to, nuclear power
control, aerospace and military purposes).
The details of warranty shall be as per the descriptions in this document and we shall not be liable for any damage on you resulting from the use of any equipment
or device (including control systems) which is not in accordance with this document (hereinafter referred to as "use in violation"). In the case where you resell our
products, we shall not be liable for any damage on a third party resulting from use in violation by the third party, and even if we make payment to the third party
in connection with such use in violation regardless of the name by which such payment may be called, we may demand the whole amount thereof from you.
①The product is neither drip proof nor dust proof structure. Never use it under the condition where water or oil drips, dust rises, or corrosion occurs.
②Never apply corrosive gases nor liquids for pressure media.
③Never take in the over-pressure exceeding the maximum pressure.
④Never short-circuit the switch output to the other terminals, nor them connect to the low impedance load that would allow the output
current over 80mA. These conduct might damege the internal circuitry.
⑤Use the stable DC power supply for the power source. Surge absorbing circuit
（diodes, varistor, etc.）is necessary if inductive load such as relay or solenoid
was connected to the power line and/or to the switch output(s).
FG terminal on the unit power supply should be earthed.（Refer the diagrams.)
⑥When handling the product, be sure to pick up the body and not to give the
excessive force to the cable.
⑦Use the neutral detergent when cleaning the body, also do not use the solvents
like lacquer thinner.
