■Precautions for Use
● Apply leakage protection with a leakage breaker installed upstream from the power system of the equipment to be protected.
∙ Do not use with voltage exceeding the maximum continuous use voltage.
∙ The product is designed for indoor use. Do not use for outdoor applications.
● Do not use in areas exposed to direct sunlight or areas exceeding the usage temperature range such as near heat sources.
● Do not use in areas exposed to wind and rain, areas where there is steam, or areas of high humidity.
● Do not use in areas with large amounts of dust or salt, or subject the product to acid, alkali, corrosive gases, solvents, cutting fluid, lubricant, etc.
● Do not apply strong vibration, impact (fall, etc.), or pressure to the product as it may cause cracking.
