EX260
Specific Product Precautions 2
Be sure to read this before handling the products. Refer to back page 50 for Safety
Instructions and pages 3 to 9 for 3/4/5 Port Solenoid Valve Precautions.
Caution
8. When connecting wires of output device, prevent
water, solvent or oil from entering inside the
connector section.
This can cause damage, equipment failure or malfunction.
9. Avoid wiring patterns in which excessive stress is
applied to the connector.
This may cause malfunction or damage to the unit due to
contact failure.
10 . Select connectors that are ø16 or less if mounting
manifolds directly using fieldwireable connectors
for SI unit power supply wiring.
Using large diameter connectors causes interference with the
mounting surface.
The following cables with connectors are recommended.

Operating Environment

Warning
1. D o n o t u s e i n a n a t m o s p h e r e c o n t a i n i n g a n
inflammable gas or explosive gas.
Use in such an atmosphere is likely to cause a fire or
explosion. This system is not explosion-proof.
Caution
1. Select the proper type of enclosure according to the
environment of operation.
IP67 is achieved when the following conditions are met.
1) Provide appropriate wiring between all units using electrical
wiring cables, communication connectors and cables with
M12 connectors.
2) Suitable mounting of each unit and manifold valve.
3) Be sure to mount a seal cap on any unused connectors.
If using in an environment that is exposed to water splashes,
please take measures such as using a cover.
When the enclosure is IP40, do not use in an operating
environment or atmosphere where it may come in contact with
corrosive gas, chemical agents, seawater, water, or water vapor.
When connected to the EX260-SPR5/6/7/8, manifold
enclosure is IP40.

Wiring Operating Environment
Caution
2. Provide adequate protection when operating in
locations such as the following.
Failure to do so may cause damage or malfunction.
The effect of countermeasures should be checked in individual
equipment and machine.
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
3. Do not use in an environment where oil and chemicals
are used.
Operating in environments with coolants, cleaning solvents,
various oils or chemicals may cause adverse effects (damage,
malfunction) to the unit even in a short period of time.
4. Do not use in an environment where the product
could be exposed to corrosive gas or liquid.
This may damage the unit and cause it to malfunction.
5. Do not use in locations with sources of surge
generation.
Installation of the unit in an area around the equipment
(electromagnetic lifters, high frequency induction furnaces,
welding machine, motors, etc.), which generates the large
surge voltage could cause to deteriorate an internal circuitry
element of th e un it o r res ult in d amag e. Imp leme nt
countermeasures against the surge from the generating
source, and avoid touching the lines with each other.
6. The product is CE marked, but not immune to
lightning strikes. Take measures against lightning
strikes in your system.
7. Keep dust, wire scraps and other extraneous
material from getting inside the product.
This may cause malfunction or damage.
8. Mount the unit in such locations, where no vibration
or shock is affected.
This may cause malfunction or damage.
9. Do not use in places where there are cyclic
temperature changes.
In case that the cyclic temperature is beyond normal
temperature changes, the internal unit is likely to be adversely
effec-ted.
10. Do not use in direct sunlight.
Do not use in direct sunlight. It may cause malfunction or
damage.
11. Use this product within the specified ambient
temperature range.
This may cause malfunction.
12. Do not use in places where there is radiated heat
around it.
Such a place is likely to cause malfunction.
