●Product handling
∗Installation
•Do not drop, hit or apply excessive shock to the SI unit.
Otherwise damage to the product can result, causing malfunction.
•Tighten to the specified tightening torque.
If the tightening torque is exceeded the mounting screws may be broken.
IP67 protection cannot be guaranteed if the screws are not tightened to the specified torque.
•If a large manifold valve is mounted, lift the unit so that stress is not applied to the connecting part while
transporting.
The stress may cause breakage of the connecting part. The unit may become very heavy depending on the
combination. Transportation/installation shall be performed by multiple operators.
•Never mount a product in a location that will be used as a foothold.
The product may be damaged if excessive force is applied by stepping or climbing onto it.
∗Wiring
•Avoid repeatedly bending or stretching the cables, or placing heavy load on them.
Repetitive bending stress or tensile stress can cause breakage of the cable.
•Wire correctly.
Incorrect wiring can break the product.
•Do not perform wiring while the power is on.
Otherwise damage to the Fieldbus system and/or input or output device can result, causing malfunction.
•Do not route wires and cables together with power or high voltage cables.
Otherwise the Fieldbus system and/or input or output device can malfunction due to interference of noise and surge
voltage from power and high voltage cables to the signal line.
Route the wires (piping) of the Fieldbus system and/or input or output device separately from power or high voltage
cables.
•Confirm proper insulation of wiring.
Poor insulation (interference from another circuit, poor insulation between terminals, etc.) can lead to excess
voltage or current being applied to the product, causing damage.
•Take appropriate measures against noise, such as using a noise filter, when the Fieldbus system is
incorporated into equipment.
Otherwise noise can cause malfunction.
∗Environment
•Select the proper type of protection according to the environment of operation.
IP67 protection is achieved when the following conditions are met.
(1)The units are connected properly with fieldbus cable with M12 connector and power cable with M12 (M8)
connector.
(2)Suitable mounting of each unit and manifold valve.
(3)Be sure to fit a waterproof cap on any unused connectors.
If using in an environment that is exposed to water splashes, please take measures such as using a cover.
Do not use in an environment where moisture or water vapor are present. Otherwise failure and malfunction can
result.
•Do not use in a place where the product could be splashed by oil or chemicals.
If the product is to be used in an environment containing oils or chemicals such as coolant or cleaning solvent, even
for a short time, it may be adversely affected (damage, malfunction etc.).
•Do not use the product in an environment where corrosive gases or fluids could be splashed.
Otherwise damage to the product and malfunction can result.
•Do not use in an area where surges are generated.
If there is equipment generating large surge near the unit (magnetic type lifter, high frequency inductive furnace,
welding machine, motor, etc.), this can cause deterioration of the internal circuitry element of the unit or result in
damage. Take measures against the surge sources, and prevent the lines from coming into close contact.
