WARNING
- The product is neither drip proof nor dust proof structure. Do not use it under the condition where water or oil drips, dust rises, or corrosion occurs
- Do not use corrosive gases or liquids as pressure media.
- Do not apply pressure exceeding the maximum pressure as shown in the specs.
- Do not short-circuit the output terminal (switch terminal) to the other terminals. Also, do not connect the load that would allow the current over the rated current. Otherwise, the internal circuitry may be damaged.
- When handling the product, be sure to pick up the body and not to give an excessive force to the cable.
- When piping, do not use a wrench to any other part than the port section, and tighten the fitting with torque less than the specified torque.
- When setting the pressure-setting trimmer (PS20), do not to apply too much force to them. The allowable torque for the pressure-setting trimmer should be no more than 0.02N-m.
- For stability, use a regulated DC power supply. Surge absorbing circuits (diodes, varistors, etc.) are necessary if inductive loads such as relays and solenoids are connected to the same power line as the products. IF using a DC power supply unit such as a switching power supply, the FG terminal should be earthed.
- Use PH neutral detergents to clean the body. Do not use lacquer thinner and other solvents for cleaning.
