Operating Environment Serial EX510 Precautions Mounting Series S0700 Specific Product Precautions 7 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. 1. Do not drop, bump, or apply excessive impact. Otherwise, the unit can become damaged, malfunction, or fail to function. 2. Hold the body while handling this product. Otherwise, the unit can become damaged, malfunction, or fail to function. 3. Observe the tightening torque range. Tightening outside of the allowable torque range will likely damage the product. 4. Do not install a unit in a place where it can be used as a scaffold. Applying any excessive load such as stepping on the unit by mistake or placing a foot on it, will cause it to break. Caution Wiring 1. Avoid miswiring. If miswired, there is a probability of damaging units or connecting devices. 2. Do not wire while energizing the product. It is likely to damage the units or connecting devices. 3. Avoid wiring the power line and high pressure line in parallel. Noise or surge produced by signal line resulting from the power line or high pressure line could cause a malfunction. Wiring of the reduced wiring system and the power line or high pressure line should be separated from each other. 4. Check the wiring insulation. Inferior insulation (contact with other circuit, insulation between terminals, etc.) will likely cause damage to the units or connecting devices due to excessive voltage or the influx of current. 1. Take measures to avoid applying repeated bending force or pulling force to the cable. Also, pay attention not to place any heavy matter on the cable or clipping. It is likely to cause a broken wire. 2. Check the grounding to maintain the safety of the reduced wiring system and for anti-noise performance. Grounding should be close to units and keep the grounding distance short. Warning Caution 1. Do not use this product in the presence of dust, particles, water, chemicals, and oil. Use with such materials is likely to cause a malfunction or breakage. 2. Do not use this product in the presence of a magnetic field. Use in such an environment is likely to cause a malfunction. 3. Do not use this product in an atmosphere containing an inflammable gas, explosive gas, or corrosive gas. Use in such an atmosphere is likely to cause a fire, explosion, or corrosion. This wire-reduced system is not explosion-proof. 4. Do not use this product 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 affected. 5. Do not use this product in places where there is radiated heat around it. Such a place is likely to cause a malfunction or breakage. 6. Do not use this product near sources that generate a surge which exceeds the benchmark test, even though this product is CE-marked certified. The internal circuit components are likely to deteriorate or become damaged when there are equipment (solenoid type lifter, high frequency guided furnace, motor, etc.) which generate a large surge around the reduced wiring system. Take measures to prevent an electrical surge and avoid having the wires touch each other. 7. Use the product type that has an integrated surge absorption element when directly driving a load which generates surge voltage by relay or solenoid valves. 8. The reduced wiring system should be installed in places with no vibration or shock. Such a place is likely to cause a malfunction or breakage. 9. Do not use in direct sunlight. Do not use in direct sunlight. It may cause a malfunction or damage. 10. Use this product within the specified ambient temperature range. This may cause a malfunction.
