Cautions
●
This product has been developed / produced for industrial use only.
●
Make sure that the power supply is off while wiring.
●
If the power is supplied from a commercial switching regulator, ensure
that the frame ground (F.G.) terminal of the power supply is connected
to an actual ground.
●
Ensure that an isolation transformer is utilized for the DC power
supply. If an autotransformer is utilized, the main body or power supply
may be damaged.
●
If the used power supply generates a surge, connect a surge absorber
to the power supply to absorb the surge.
●
Short-circuiting the load or wrong wiring may burn or damage the
product.
●
Do not run the wires together with high-voltage lines or power lines
or put them in the same raceway. This can cause malfunction due to
induction.
● Avoid using the product where there are strong magnetic fields as they
may prevent the product from working according to the specification.
●
Verify that the supply voltage including the ripple is within the rating.
●
In case noise generating equipment (switching regulator, inverter
motor, etc.) is used in the vicinity of this product, connect the frame
ground (F.G.) terminal of the equipment to an actual ground.
●
Do not apply stress directly to the sensor cable joint by forcibly
bending or pulling.
●
Do not use the product in dusty or dirty places or in places that are
exposed to steam.
●
Protect the sensor from water, oil, grease, organic solvents such as
thinner, etc., strong acid, and alkaline.
● This product cannot be used in an environment containing inflammable
or explosive gasses.
●
Never disassemble or modify the product.
●
Make the cable length as short as possible to avoid noise.
