2 3 + 1 DC circuit AC circuit Varistor SOL. Varistor Varistor SOL. 1. As a rule, use electrical wire with a cross sectional area of 0.5 to 1.25 mm2 for wiring. Furthermore, do not allow excessive force to be applied to the lines. 2. Use electrical circuits which do not generate chattering in their contacts. 3. Use voltage which is within ±10% of the rated voltage. In cases with a DC power supply where importance is placed on responsiveness, stay within ±5% of the rated value. The voltage drop is the value in the lead wire section connecting the coil. 4. When a surge from the solenoid affects the electrical circuitry, install a surge absorber, etc., in parallel with the solenoid. Or, adopt an option that comes with the surge voltage protection circuit. (However, a surge voltage occurs even if the surge voltage protection circuit is used. For details, please consult with us.)

Storage In the case of long term storage, thoroughly remove all moisture to prevent rust and deterioration of rubber materials, etc. 2. Exhaust the drain from an air filter periodically. Caution 1. Do not use the valves in an atmosphere having corrosive gases, chemicals, salt water, water, steam, or where there is direct contact with any of these. 2. Do not use in explosive atmospheres. 3. Do not use in locations subject to vibration or impact. 4. Do not use in locations where radiated heat will be received from nearby heat sources. 5. Employ suitable protective measures in locations where there is contact with water droplets, oil or welding spatter, etc. Operating Environment Warning 1. Removing the product 1) Shut off the fluid supply and release the fluid pressure in the system. 2) Shut off the power supply. 3) Dismount the product. 2. Low frequency operation Switch valves at least once every 30 days to prevent malfunction. Also, in order to use it under the optimum state, conduct a regular inspection once a half year.
