Wiring Operating Environment Caution Caution Serial EX600 Precautions Series S0700 Specific Product Precautions 10 Be sure to read before handling. Refer to front matter 53 for Safety Instructions, Pages 3 to 8 for 3/4/5 Port Solenoid Valve Precautions. 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 a 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. 2. Provide adequate protection when operating in locations such as the following. 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 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 a malfunction or damage. 9. Mount the unit in such locations, where no vibration or shock is affected. This may cause a 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 a malfunction or damage. 12. Use this product within the specified ambient temperature range. This may cause a malfunction. 13. Do not use in places where there is radiated heat around it. Such a place is likely to cause a malfunction. 982
