Safety Instructions (continued)
Note
•When conformity to UL is required, the SI unit should be used
with a UL1310 Class 2 power supply.
Follow the instructions given below when handling your product.
Or, it will have a risk of being damaged and operating failure.
•Operate product with the specified voltage.
•Reserve a space for maintenance.
•Do not remove labels.
•Do not drop, hit or apply excessive shock to the product.
•Follow the specified tightening torque.
•Never mount a product in a location that will be used as a
foothold.
•Do not bend or apply tensile force to cables, or apply force by
placing heavy load on them.
•Connect wires and cables correctly.
•Do not connect wires while the power is on.
•Do not lay wires or cables with power line or high-voltage line in
the same wiring route.
•Verify the insulation of wiring.
•Separate power line for solenoid valves from power line for
Input and control unit.
•Take appropriate measures against noise, such as using a
noise filter, when the product is incorporated into equipment.
•Select the proper type of protection according to the
environment of operation.
•Take sufficient shielding measures when installing at the
following place.
(1) A place where noise due to static electricity is generated
(2) A place where electric field strength is high
(3) A place where there is radioactive irradiation
(4) A place near power line
•Do not use the product near by a place where electric surges
are generated.
•When a surge-generating load such as a relay or solenoid is
driven directly, use an product with a built-in surge absorbing
element.
•The product is CE marked, but not immune to lightning strikes.
Take measures against lightning strikes in the system.
•Prevent foreign matter such as remnant of wires from entering
the product to avoid failure and malfunction.
•Mount the product in a place that is not exposed to vibration or
impact.
•Do not use the product in an environment that is exposed to
temperature cycle.
•Do not expose the product to direct sunlight.
•Keep the specified ambient temperature range.
•Do not expose the product to heat radiation from a heat source
located nearby.
•Set the switches by using a sharp-pointed screwdriver etc.
•Turn off the power supply, stop the supplied air, exhaust the
residual pressure and verify the release of air before performing
maintenance.
•Perform maintenance and check regularly.
•Perform a proper functional check.
•Do not use solvents such as benzene, thinner etc. to clean the
product.
