EX600 Precautions Wiring Caution 7. When a reduced wiring system is installed in machinery/equipment, provide adequate protection against noise by using noise filters, etc. Noise in signal lines may cause malfunction. 8. When connecting wires of input/output device or handheld terminal, prevent water, solvent or oil from entering inside from the connecter section. This can cause damage, equipment failure, or malfunction. 9. Avoid wiring patterns in which excessive stress is applied to the connector. This may cause malfunction or damage to the unit due to contact failure. Operating Environment Warning 1. Do not use in an atmosphere containing an inflammable gas or explosive gas. Use in such an atmosphere is likely to cause a fire or explosion. This system is not explosion-proof. Operating Environment Caution 3. Do not use in an environment where oil and chemicals are used. Operating in environments with coolants, cleaning solvents, various oils or chemicals may cause adverse effects (damage, malfunction) to the unit even in a short period of time. 4. Do not use in an environment where the product could be exposed to corrosive gas or liquid. This may damage the unit and cause it to malfunction. 5. Do not use in locations with sources of surge generation. Installation of the unit in an area around the equipment (electromagnetic lifters, high frequency induction furnaces, welding machine, motors etc.), which generates the large surge voltage could cause to deteriorate an internal circuitry element of the unit or result in damage. Implement countermeasures against the surge from the generating source, and avoid touching the lines with each other. 6. Use the product type that has an integrated surge absorption element when directly driving a load which generates surge voltage by relay, solenoid valves or lamp. When a surge generating load is directly driven, the unit may be damaged. 7. The product is CE marked, but not immune to lightning strikes. Take measures against lightning strikes in your system. 8. Keep dust, wire scraps and other extraneous material from getting inside the product. This may cause malfunction or damage. 9. Mount the unit in such locations, where no vibration or shock is affected. This may cause malfunction or damage. 10. Do not use in places where there are cyclic temperature changes. In case that the cyclic temperature is beyond normal temperature changes, the internal unit is likely to be adversely effected. 11. Do not use in direct sunlight. Do not use in direct sunlight. It may cause malfunction or damage. 12. Use this product within the specified ambient temperature range. This may cause malfunction. 13. Do not use in places where there is radiated heat around it. Such a place is likely to cause malfunction. Caution 1. Select the proper type of enclosure according to the environment of operation. IP65/67 protection class is achieved when the following conditions are met. 1) The units are connected properly with wiring cable for power supply, communication connector, and cable with M12 connector. 2) Suitable mounting of each unit and manifold valve. 3) Be sure to mount a seal cap on any unused connectors. If using in an environment that is exposed to water splashes, please take measures such as using a cover. For IP40 protection class, do not use in atmospheres with corrosive gas, chemicals, sea water, water, steam, or where there is direct contact with any of these. When EX600-D�ｮ�ｮE or EX600-D�ｮ�ｮF are connected, the enclosure of the manifold should be IP40. Also, the Handheld Terminal confirms to IP20, so prevent foreign matter from entering inside, and water, solvent or oil from coming in direct contact with it. 2. Provide adequate protection when operating in locations such as follows. Failure to do so may cause damage or malfunction. The effect of countermeasures should be checked in individual equipment and machine. 1) Where noise is generated by static electricity, etc. 2) Where there is a strong electric field 3) Where there is a danger of exposure to radiation 4) When in close proximity to power supply lines Series VQC4000 Specific Product Precautions 5 Be sure to read before handling.
