SMC Networks JSXF Series Operation Manual page 5

1. Precautions for Design
Warning
1. Confirm the specifications.
Give careful consideration to the operating conditions such as the applications, fluids, voltage and
environment, and use within the specified operating range.
If the product is used outside the specification range, it could lead to damage and malfunction.
SMC does not guarantee against any damage if the product is used outside of the specification range.
2. Cannot be used as an emergency shutdown valve, etc.
This product is not designed for safety applications such as an emergency shutdown valve.
If the valves are used in this type of system, other reliable safety assurance measures should also be
adopted.
3. Cannot be used for holding pressure (including vacuum).
Since the valves are subject to air leakage, they cannot be used for applications such as holding pressure
(including vacuum) in a pressure vessel.
4. Energizing valves continuously for an extended period of time
The solenoid coil generates heat if continuously energized. Do not use the product in sealed containers.
Install the product in a ventilated location. Do not touch the valves with bare hand during or after
energization.
5. Dual pressure
If there is a possibility that reverse pressure will be applied, take countermeasures such as mounting a
check valve on the outlet side of the valve.
6. Disassembly and modification prohibited
Do not disassemble the product and replacement parts or make any modifications, including additional
machining. It may cause human injury and/or an accident.
2. Precautions for Operating Environment
Warning
1. Do not use this product under any of the following conditions. It may lead to a malfunction or failure.
1) An environment containing corrosive gases, chemicals, sea water, water, steam, or locations where there
is direct contact with any of these
2) Locations with explosive environment
3) Locations subject to direct sunlight
4) Locations subject to an excessive vibration or impact
5) Locations where radiant heat will be received from nearby heat sources
2. Take protective measures such as installing an enclosure (waterproof cover) in an environment where
the product becomes wet with water.
The protection grade of this product is IP67 (IEC60529), but if water enters the product from a minute gap, it
may lead to a malfunction or failure. Take protective measures when using the product in any of the following
environments.
<Examples of environments where the product becomes wet with water>
1) Underwater
2) Locations where steam is generated
3) Locations where the product is exposed to water for a long time
4) Locations where water or oil splashes from the surrounding equipment
5) Locations where sea water is present
3. Use of the product outdoors
When using the product outdoors, take appropriate protective measures.
1) Provide a protective cover, etc. so that the product will not be exposed to direct sunlight.
2) Cover the product with an enclosure so that the product will not be exposed to rain or wind.
Even if you provide only a roof-type cover on top of the product, the product may become wet with water
due to crosswind or rebounding of rain water from the ground. When covering the product with an
enclosure, also take ventilation measures so that it will not be filled with heat due to long time
energization.
