1. These products are intended for use in general factory
automation equipment.
Avoid using these products in machinery/equipment which
affects human safety, and in cases where malfunction or failure
can result in extensive damage.
2. Do not use in explosive environments, in the presence of
inflammable gases, or in corrosive environments. This can
cause injury or fire.
3. Work such as transporting, installing, piping, wiring,
operation, control and maintenance should be performed
by knowledgeable and qualified personnel only. As
handling involves the risk of a danger of electrocution,
injury or fire.
4. Install an external emergency stop circuit that can promptly
stop operation and shut off the power supply.
5. Do not modify these products. Modifications done to these
products carry the risk of injury and damage.
1. Read the instruction manual carefully, strictly observe the
precautions and operate within the range of the
specifications.
2. Do not drop these products or submit them to strong
impacts. This can cause damage, failure or malfunction.
3. In locations with poor electrical conditions, take steps to
ensure a steady flow of the rated power supply. Use of a
voltage outside of the specifications can cause malfunction,
damage to the unit, electrocution or fire.
4. Do not touch connector terminals or internal circuit
elements when current is being supplied. There is a danger
of malfunction, damage to the unit or electrocution if
connector terminals or internal circuit elements are
touched when current is being supplied.
Be sure that the power supply is OFF when adding or removing
manifold valves or input blocks or when connecting or
disconnecting connectors.
5. Operate at an ambient temperature that is within the
specifications. Even when the ambient temperature range
is within the specifications, do not use in locations where
there are rapid temperature changes.
6. Keep wire scraps and other extraneous materials from
getting inside these products. This can cause fire, failure or
malfunction.
7. Give consideration to the operating environment
depending on the type of enclosure being used.
To achieve IP65 and IP67 protection class, provide appropriate
wiring between all units using electrical wiring cables,
communication connectors and cables with M12 connectors.
Also, provide waterproof caps when there are unused ports, and
perform proper mounting of input units, input blocks, SI units and
manifold valves. Provide a cover or other protection for
applications in which there is constant exposure to water.
8. Use the proper tightening torques.
There is a possibility of damaging threads if tightening exceeds
the tightening torque range.
9. Provide adequate protection when operating in locations
such as follows:
• Where noise is generated by static electricity
• Where there is a strong electric field
• Where there is a danger of exposure to radiation
• When in close proximity to power supply lines
10. When these products are installed in equipment, provide
adequate protection against noise by using noise filters.
11. Since these products are components whose end usage
is obtained after installation in other equipment, the
customer should confirm conformity to EMC directives for
the finished product.
12. Do not remove the name plate.
13. Perform periodic inspections and confirm normal
operation, otherwise it may be impossible to guarantee
safety due to unexpected malfunction or erroneous
operation.
14. Do not use in places where there are cyclic temperature
changes.
In case that the cyclic temperature is beyond normal
temperature changes, the inside product is likely to be
adversely effected.
15. Do not use in direct sunlight.
Do not use in direct sunlight. It may cause malfunction or
damage.
16. Do not use in places where there is radiated heat around
it.
Such a place is likely to cause malfunction.
Safety Instructions on Power Supply
1. Operation is possible with a single power supply or a
separate power supply. However, be sure to provide two
wiring systems (one for solenoid valves, and one for input
and control units).
2. When it is UL compliant, use a class 2 power supply unit in
accordance with UL1310 for a combined direct current
power supply.
Safety Instructions on Cable
1. Avoid miswiring, as this can cause malfunction, damage
and fire in the unit.
2. To prevent noise and surge in signal lines, keep all wiring
separate from power lines and high-voltage lines.
Otherwise, this can cause malfunction.
3. Check wiring insulation, as defective insulation can cause
damage to the unit when excessive voltage or current is
applied.
4. Do not bend or pull cables repeatedly, and do not place
heavy objects on them or allow them to be pinched. This
can cause broken lines.
