Wiring
Warning
1. When electric power is connected to a solenoid valve, be careful to apply the proper
voltage. Improper voltage may cause malfunction or coil damage.
2. Excessive force applied to the cable connector may cause disconnection. Do not apply
repetitive bending, tensile, or heavy loads to the cable.
3. Tighten the connector with hand. Use of tools may damage the connectors.
4. Do not unnecessarily pull on connectors or cables.
Air Source
Warning
1. Use clean air. Do not use compressed air containing chemicals, organic solvent, synthetic
oil or corrosive gas as it may be cause of breakage of components or operation failure.
2. Air containing too much moisture may cause malfunction. Install an air drier or aftercooler before
the regulator.
Caution
1. Install an air filter at the upstream side of this product. Select an air filter with a filtration
degree of 5
μ
m or finer.
2.
If an excessive amount of carbon powder is present, install a mist separator on the
upstream side. If excessive carbon dust is generated by the compressor, it may adhere to
the inside of this product and cause it to malfunction.
Refer to SMC’s “Air Cleaning Equipment” catalog for further details on compressed air quality.
Operating Environment
Warning
1. Do not use in atmospheres contacting corrosive gases, chemicals, sea water, water, water
steam, or where there is direct contact with any of these.
2. Do not use in explosive atmosphere.
3. Do not use in locations subject to vibration or impact.
4. Do not expose to direct sunlight for an extended period of time. Protective cover should be used
to shield.
5. Do not mound in locations where is nearby heat source. Radiated heat should be also prevented.
6. Implement suitable protective measures in locations where there is contact with water droplets,
oil, or welding spatter.
7. Install a silencer into exhaust port to prevent the dust ingress if there is a lot of dust in
atmosphere, as dust may cause air leakage.
