Specific Product Precautions 2
Be sure to read this before handling the products.
EX430
Series
Wiring
Caution
6. When the product is installed in machinery/equip-
ment, provide adequate protection against noise by
using noise filters, etc.
Noise in signal lines may cause a malfunction.
7. When connecting wires, prevent the entry of water,
solvent, or oil from the connector section.
Failure to do so may result in damage, equipment failure, or
malfunction.
8. Avoid wiring patterns in which excessive stress is
applied to the connector.
Failure to do so may result in equipment failure or malfunction
due to contact failure.
Operating Environment
Warning
1. Do not use in atmospheres containing inflammable
or explosive gases.
Use in such atmospheres is likely to cause a fire or explosion.
This product is not explosion proof.
Caution
1. Provide adequate protection when operating in lo-
cations such as the following.
Failure to do so may cause a malfunction or equipment failure.
The effect of countermeasures should be checked in individu-
al equipment and machines.
1) Where noise is generated by static electricity, etc.
2) Where there is a strong electric field
3) Where there is a danger of exposure to radiation
4) When in close proximity to power lines or high-voltage lines
2. Do not use in environments where oil and chemi-
cals are used.
Operating in environments where coolants, cleaning solvents,
various oils, or chemicals are present may cause adverse ef-
fects (damage, malfunction, etc.) to the product even within a
short period of time.
3. Do not use in environments where the product
could be exposed to corrosive gases or liquids.
Use in such environments may cause product damage or mal-
function.
Operating Environment
Caution
4. Select the proper type of enclosure according to
the operating environment.
IP69K is achieved when the following conditions are met.
1) Provide appropriate wiring using communication cables
with M12 connectors.
2) Appropriately mount the SI unit and the manifold valve.
5. Do not use in locations with sources of surge gen-
eration.
Installation of the product in an area around equipment
(electromagnetic lifters, high-frequency induction furnaces,
welding machines, motors, etc.) which generates large surge
voltages could cause an internal circuitry element of the
product to deteriorate or result in damage. Implement coun-
termeasures against the surge from the generating source,
and avoid contact between the lines.
6. When directly driving a load which generates a
surge voltage by relay, solenoid valve, or lamp,
use a load that has an integrated surge-absorption
element.
When a surge generating load is directly driven, the product
may be damaged.
7. The product is CE marked but not immune to light-
ning strikes. Take measures against lightning
strikes in your system.
8. Keep dust, wire scraps, and other foreign matter
from entering the product.
Such materials may cause equipment failure or malfunction.
9. Mount the product in a location, which is not af-
fected by vibration or shock.
Failure to do so may cause equipment failure or malfunction.
10. Do not use in direct sunlight.
This may cause equipment failure or malfunction.
11. Use within the ambient temperature range.
Failure to do so may cause a malfunction.
12. Do not use in places where radiated heat may af-
fect the product.
Such places are likely to cause a malfunction.
