Warning 1. Check the product specifications before use. If the product is used outside of the specifications, it may cause malfunction, failure or damage to the product, leading to an electric shock, explosion or fire. 2. Do not modify the product. Do not disassemble, modify (including changing the printed circuit board) or repair the product. An injury or failure can result. 3. The product should be mounted correctly. If the product is not mounted correctly, malfunction, failure or damage may occur. For the handling of fittings (including One-touch fittings), refer to the Precautions for Fittings and Tubing. Refer to the operation manual for the products in item 3 below. ・Use the appropriate tool. ・Tighten with the required torque. ・If the mounting direction is specified, mount the product in accordance with the direction. 4.Perform regular maintenance and confirm normal operation. If maintenance is not performed, malfunction or failure may occur. Turn off the power supply and stop the fluid supply before performing maintenance. Otherwise, it may cause an injury. After maintenance is complete, perform appropriate functional inspections and leak tests. Safety cannot be assured in the case of unexpected malfunction. Cut off the power supply and stop supplying fluid if the equipment does not function properly or there is leakage of fluid. 5. Do not apply vibration, impact or loads. If vibration, impact or loads are applied, malfunction, failure or damage may occur. In particular, never mount a product in a location that will be used as a foothold. 6. Do not expose the product to direct sunlight. If the product is exposed to direct sunlight, malfunction, failure or damage may occur. If the product is exposed to direct sunlight, provide a suitable protective cover. 7.Do not use the product in an environment where the product may be corroded. If the product is used in a corrosive environment, malfunction, failure or damage may occur. Check the product materials before use. 8. Do not use products other than ATEX compliant products in an environment where the product is exposed to explosive or flammable gas or dust. ATEX (explosion proof) compliant products should be used in an environment which is correspondent to ATEX compliance. If products other than ATEX compliant products are used in an explosive or flammable environment, an explosion or fire may occur. 9.Ensure that the product is used within the enclosure specifications. If the product is used outside of the specifications, malfunction or failure may occur. Use the product in accordance with the protection level with reference to IEC60529. 10. Use the product within the operating temperature, humidity and fluid temperature. Do not use the product outside of these specifications. Even when the product is used within the specifications, do not use in a location where there are rapid temperature changes, or in a location where there are heating/cooling cycles, or in a location where there is freezing or condensation. It may result in malfunction or failure. If the product is to be used in under low temperature, protection against freezing is necessary. 11. Do not use fluids other than applicable fluids. If fluids other than applicable fluids are used, malfunction, failure or breakage may occur. 12. Do not use for flammable or poisonous fluids. If flammable or poisonous fluids are used, an explosion or fire may occur. 13. Do not let foreign matter or condensate get inside the piping of the product. If foreign matter or condensate enters the product, malfunction, failure or damage may occur. Mount an appropriate filter on the fluid inlet side (IN side). 14. Use the product within the specified operating pressure range. If the product is used outside of the rated pressure range, malfunction may occur. 15. Do not apply pressure which exceeds the proof pressure. If pressure exceeding the proof pressure is applied, malfunction, failure or damage may occur. 16. Ensure that the product is used within the power supply specifications. If the product is used outside of the specifications, malfunction or failure may occur, leading to an electric shock or fire. 17. Ensure that the FG terminal is connected to ground when using a commercially available switch-mode power supply. When a switch-mode power supply is connected to the product, switching noise will be superimposed and the product specification can no longer be met. This can be prevented by inserting a noise filter, such as a line noise filter and ferrite core, between the switch-mode power supply and the product, or by using a series power supply instead of a switch-mode power supply. 18. Do not use a load exceeding the maximum load voltage or current. If the product is used outside of the specifications, it may cause malfunction or damage, leading to a reduction in the life of the product. 19. Wire the product correctly. Incorrect wiring could cause malfunction or failure, leading to an electric shock or fire. Pressure Switches/Flow Switches Precautions 1 Be sure to read this before handling.
