    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), Japan Industrial Standards (JIS) and other safety regulations *1) ISO 4414: Pneumatic fluid power - - General rules relating to systems.
  • Page 4 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 has been written for those who have knowledge of machinery and apparatus that use pneumatic equipment and have full knowledge of assembly, operation and maintenance of such equipment. ♦Please read this operation manual carefully and understand it before assembling, operating or providing maintenance to the product.
  • Page 6 ■NOTE ○Follow the instructions given below when designing, selecting and handling the product. ●The instructions on design and selection (installation, wiring, environment, adjustment, operation, maintenance, etc.) described below must also be followed. ∗Product specifications •The direct current power supply to combine should be UL approved as follows. Circuit (of class 2) which is of maximum 30Vrms (42.4 V peak) or less, with UL 1310 class 2 power supply unit or UL 1585 class 2 transformer.
  • Page 7 ∗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 to be off the connector. •Avoid repeatedly bending or stretching the lead wire, or placing heavy load on them. Repetitive bending stress or tensile stress can cause the sheath of the wire to peel off, or breakage of the wire.
  • Page 8 ∗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 surges are generated.
  • Page 9 ∗Adjustment and Operation •Turn the power on after connecting a load. Otherwise it can cause excess current causing instantaneous breakage of the product. •Do not short-circuit the load. Although error is displayed when the product load is short circuit, generated excess current lead to cause the damage of the product.

  • Page 18: Wiring

    ■Wiring Connection •Make connection after turning the power off. •Install the lead wire separately from the route for power cable or high-voltage cable. Otherwise, malfunction may potentially result due to noise. •Be sure to ground Terminal FG when using a switching regulator obtained on the commercial market. If analogue output is performed connecting to a switching regulator obtained on the market, switching noise will be superimposed and product specification can no longer be met.
