NOTE: This equipment has been tested and found to comply w i th the limits for a Class A digi tal de vice, pursuant to P art 15 of the FCC Rules. These limits are designed to provide reasonable protection a g ainst harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequ ency energy and, if n ot installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. This can lead to incorrect maintenance, or misreading of the operation manual, w hi ch could cause damage or malfunction to the product. Some connected loads can apply an initial charge current which will activate the over current protection fun c tion, causing the unit to malfunction. If the tightening torque is exceeded the mounting screws may be broken. The stress may cause breakage of the connecting part. The unit may become very heavy depending on the combination. IP67 protection class is achieved when the following conditions are met. (1) The units a re connected properly with fieldbus cable with M 1 2 connector and power cable with M12 (M8) connector. (2) Suitable mounting of each unit and manifold valve. (3) Be sure to fit a waterproof cap on any unused connectors. If using in an environment that is exposed to water splashes, please take measures such as using a cover. Do not use in an environment where moisture or water vapor are present. If there is equipment generating large surge near the unit (magnetic typ e lifter, high frequency inductive furnace, welding machine, motor, etc.), this can cause deterioration of the internal circuitry element of the unit or result in damage. T ake measures against the surge sources, and pre vent the lines from coming into close contact. If using in a location directly exposed to sunlight, shade the product from the sunlight.S top operation if the equipment does not function properly.Use a soft cloth to remove st ains.

For heavy stains, use a cloth soaked w i th diluted neutral detergent and fully squeezed, then w i pe up the stains again with a dry cloth. For use in other countries, please co nsult SMC. SMC will not be res ponsible for an y secondary failure which may cause an accident or dam age to other devices or equ ipment. ?
