Page 3: Safety Precautions
！ Always read this section before starting use. When designing and manufacturing a device using CKD products, the manufacturer is obligated to check that device safety mechanical mechanism, pneumatic control circuit, or water control circuit and the system operated by electrical control that controls the devices is secured. - Page 4 Items Related to Design and Selection Specification check Never use for flammable fluids. ！ DANGER: Use within the specification range characteristic to the product. ！ WARNING: The product is designed for use only in the compressed air system. Fracture and malfunction will be caused at pressures or temperatures outside the specification range.

Page 5: Operating Environment
Operating environment Never use in the explosive gas atmosphere. Because the ！ DANGER: product does not have an explosion-proof structure, explosion and fire may be caused. If the product is used for nitrogen gas, there is danger of oxygen deficiency. Follow the precautions below and take sufficient care of handling. - Page 6 Items Related to Installation and Adjustment Installation Use at specification source voltage and output. ！ DANGER: If voltages exceeding the specification voltage limit are added, malfunction, sensor breakage and electric shock and fire will be caused. Do not use loads exceeding the output rating. Otherwise breakage in the output circuit and/or fire will be caused.
- Page 7 CAUTION: ！ The product is designed to have no resistance against lightning surges. Though the product complies with CE marking, no resistance against lightning surges is designed. Take protective measures against lightning surges on the equipment side if necessary. Do not allow repetitive bending forces or tension applied on lead wires.
