Environment
Do not use the product in an environment that is constantly exposed to the splash of water.
Otherwise failure or malfunction can result. Take measures such as using a cover.
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 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 electrical surges are generated.
If there is equipment generates a large electrical surge (solenoid type lifter, high frequency induction furnace, motor,
etc.) close to the product, damage or failure of the internal circuit may occur. Take measures against the surge
sources, and prevent the wires from coming into close contact.
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.
Do not use the product in areas that are 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 wire debris from entering the product.
Otherwise failure or malfunction can result.
Do not use the product in areas subject to large temperature cycle.
Heating/cooling cycles other than ordinary changes in temperature can adversely affect the internal structure of the
product.
Do not expose the product to direct sunlight.
If using in a location directly exposed to sunlight, use a suitable protective cover.
Otherwise failure or malfunction can result.
Keep within the operating fluid temperature and operation temperatures range.
The operating fluid temperature range is 0 to 50
operating temperature range is 0 to 50
If the fluid freezes, it may cause damage and malfunction of the product, so please take measures to prevent
freezing.
When a fluid at a lower temperature than the ambient temperature is supplied, the product can break due to
condensation and malfunction. Keep the product from having condensation.
Please be aware that water droplets may cause early deterioration/damage, particularly if the product is installed
vertically or upside-down.
Protection against freezing is necessary.
Avoid sudden temperature change even within specified temperature. Otherwise failure or malfunction can result.
Do not operate close to a heat source, or in a location exposed to radiant heat.
Otherwise malfunction can result.
