  • Page 3: Safety Instructions

    Safety Instructions These safety instructions are intended to prevent hazardous situations and/or equipment damage. These instructions indicate the level of potential hazard with the labels of "Caution", "Warning" or "Danger". They are all important notes for safety and must be followed in addition to International Standards (ISO/IEC) and other safety regulations.
  • Page 4 Safety Instructions Caution 1.The product is provided for use in manufacturing industries. The product herein described is basically provided for peaceful use in manufacturing industries. If considering using the product in other industries, consult SMC beforehand and exchange specifications or a contract if necessary. If anything is unclear, contact your nearest sales branch.
  • Page 5 Operator This operation manual is intended for those who have knowledge of machinery using pneumatic equipment, and have sufficient knowledge of assembly, operation and maintenance of such equipment. Only those persons are allowed to perform assembly, operation and maintenance. Read and understand this operation manual carefully before assembling, operating or providing maintenance to the product.
  • Page 6 Caution ■Do not touch the terminals and connectors while the power is on. Otherwise electric shock, malfunction or damage to the product can result. ■After maintenance is complete, perform appropriate functional inspections and leak tests. Stop operation if the equipment does not function properly or there is a leakage of fluid. When leakage occurs from parts other than the piping, the product might be faulty.
  • Page 7 ●Product handling Installation Tighten to the specified tightening torque. If the tightening torque is exceeded the mounting screws and brackets may damaged. If the tightening torque is insufficient, the product may be displaced and the mounting screws may come loose (Refer to page "Mounting and Installation".) Do not apply excessive stress to the product when it is mounted with a panel mount.
  • Page 8 Wiring Do not pull the lead wires. In particular, never lift a product equipped with fitting and piping by holding the lead wires. Otherwise damage to the internal parts can result, causing malfunction or disconnection of the connector. Avoid repeatedly bending or stretching the lead wire, or placing heavy loads on it Repeated bending stress or tensile stress can cause damage to the sheath, or breakage of the wires.
  • Page 9 Environment Do not use the product in area that is exposed to corrosive gases, chemicals, sea water, water or steam. Otherwise failure or malfunction can result. Do not use in a place where the product could be splashed by oil or chemicals. If the product is to be used in an environment containing oils or chemicals such as coolant or cleaning solvent, even for a short time, it may be adversely affected (damage, malfunction, or hardening of the lead wires) Do not use in an area where electrical surges are generated.
  • Page 10 Adjustment and Operation Connect load before turning on the power. Do not short-circuit the load. Although an error is displayed when the product load is short circuited, excess current may cause damage to the product. Do not press the setting buttons with a sharp pointed object. This may damage the setting buttons.
