WARNING This product is not designed or rated for ensuring safety of persons either directly or indirectly. Do not use it for such purposes. Never use this product with an AC power supply. Otherwise, explosion may result. ● Design Influence of Surrounding Metal When mounting the Sensor within a metal panel, ensure that the clearances given in the following table are maintained. ｌ The following precautions must be observed to ensure safe operation. (1) Do not use the Sensor in an environment where inflammable or explosive gas is present. (2) Do not attempt to disassemble, repair, or modify any Sensors. (3) Power Supply Voltage Do not use a voltage that exceeds the rated operating voltage range. Applying a voltage that is higher than the operating voltage range may result in explosion or fire. (4) Incorrect Wiring Be sure that the power supply polarity and other wiring is correct. Incorrect wiring may cause explosion or fire. (5) Connection without a Load If the power supply is connected directly without a load, the internal elements may explode or burn. Be sure to insert a load when connecting the power supply. (6) This Sensor received UL Standard certification under the assumption that the Sensor will be used in a Class 2 circuit. When using the Sensor in the United States or Canada, be sure to use it in a Class 2 circuit. n m d dia.
