∗Environment
•Do not use the product in area that is exposed to corrosive gases, chemicals, sea water, water or steam.
Otherwise failure or 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, or hardening of the lead wires)
•Do not use in an area where surges are generated.
If there is equipment which generates a large amount of surge (solenoid type lifter, high frequency induction furnace,
motor, etc.) close to the product, this may cause deterioration or breakage of the internal circuit of the product.
Avoid source.
•Do not use a load which generates surge voltage.
When a surge-generating load such as a relay or solenoid is driven directly, use a 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.
•Mount the product in a place that is not exposed to vibration or impact.
Otherwise failure or malfunction can result.
•Do not use the product in the presence of a magnetic field.
This may lead to the malfunction of the product.
•Prevent foreign matter such as remnant of wires from entering the product.
Take proper measures for the remnant not to enter the product in order to prevent failure or malfunction.
•Do not use the product in an environment that is exposed to temperature cycle.
Heat cycles other than ordinary changes in temperature can adversely affect the inside of the product.
•Do not expose the product to direct sunlight.
If using in a location directly exposed to sunlight, shade the product from the sunlight.
Otherwise failure or malfunction can result.
•Keep within the specified fluid and ambient temperatures range.
Ambient temperature range is 0 to 50 °C.
Operation under low temperature leads to cause damage or operation failure due to frozen moist in the fluid or air.
Protection against freezing is necessary.
Avoid sudden temperature change even within specified temperature.
•Do not operate close to a heat source, or in a location exposed to radiant heat.
Otherwise malfunction can result.
