• [In Use]
• Do not insert a foreign object such as a wire into the joint as it will damage the diaphragm inside.
• Tighten the cable wiring port firmly with the attached cable gland, and take measures to prevent water from entering.
• Depending on the operating environment, the cable gland or the cover of the main body may become loose, and the waterproof property may be lowered. Therefore, prevent the cable gland from becoming loose or tighten the cover periodically.
• Since this product introduces atmospheric pressure through a cable, it is recommended to use a cable with a built-in atmospheric pressure introduction tube.
• Wiring should be done with the power OFF. Please note that short-circuiting between terminals may damage the internal circuit. Also, be careful not to miswire.
