●Product handling
Mounting
Do not drop, hit or apply excessive shock to the product.
The product will be damaged, leading to failure and malfunction.
Tighten to the specified tightening torque.
If the tightening torque is exceeded, the mounting screws can be broken.
Never mount the 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 (Including connecting/disconnecting of the connectors)
Avoid repeatedly bending or stretching the cables, or placing a heavy load on them.
Applying repeated bending and tensile stress to the cable can break the circuit.
Wire correctly.
Incorrect wiring can cause damage the product.
Do not perform wiring while the power is on.
Incorrect wiring can damage the SI unit and/or input/output equipment and malfunction can result.
Do not route wires and cables together with power or high voltage cables.
The product can malfunction due to interference of noise and surge voltage from power and high voltage cables to
the signal line.
Wiring of the SI unit and the input/output device and the power cable or high voltage cable should be separated
from each other.
Confirm correct insulation of wiring.
Poor insulation (interference with other circuits, poor insulation between terminals etc.) can apply excessive
voltage or current to the SI unit and input/output device causing damage to them.
When an SI unit is installed in machinery/equipment, provide adequate protection against noise by
using noise filters, etc.
Noise in signal lines may cause malfunction.
Operating environment
Select the correct type of enclosure according to the operating environment.
For reduced wiring for IP20, do not use it in an environment where it is subject to water or oil splashes.
IP65/67 protection class is achieved when the following conditions are met.
(1) The units are connected correctly using a fieldbus cable with M12 connector and power cable with M12 (M8)
connector.
(2) Suitable mounting of each unit and manifold valve.
If using in an environment that is exposed to water splashes, please take protective measures, such as using a
cover.
Do not use the product in an environment where corrosive gases or fluids can be splashed.
Otherwise damage to the SI can result, causing malfunction.
Do not use the product in an area where surges are generated.
If there is equipment generating large surge near the SI unit (magnetic type lifter, high frequency inductive furnace,
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.
When a surge-generating load such as a relay or solenoid is directly driven, use the product with built in
surge protection.
When a surge generating load is directly driven, the SI unit may be damaged.
The product is CE marked, but not immune to lightning strikes. Take measures against lightning strikes
in the system.
Do not let foreign matter, such as wire debris, get inside the product.
Otherwise it can cause damage or malfunction.
