Do not impose an excessive voltage on the E2A, otherwise it may be damaged. Do not impose AC current (100 to 240 VAC) on any DC Connection with No Load model, otherwise it may be damaged. Be sure to insert loads when wiring. Make sure to connect a proper Load Short-circuit load to the E2A in operation, otherwise it may damage internal ele- ments. Do not short-circuit the load, or the E2A may be damaged. Do not expose the product to flammable or explo- The E2A’s short-circuit protection function will be valid if the polarity sive gases. of the supply voltage imposed is correct and within the rated voltage range. Do not disassemble, repair, or modify the product. Power OFF Correct Use The Proximity Sensor may output a pulse signal when it is turned Designing OFF. Therefore, it is recommended that the load be turned OFF Power Reset Time before turning OFF the Proximity Sensor. The Proximity Sensor is ready to operate within 100 ms (160ms for Power Supply Transformer NO+NC -B3 / -C3 types) after power is supplied. If power supplies are connected to the Proximity Sensor and load respectively, be sure When using a DC power supply, make sure that the DC power sup- to supply power to the Proximity Sensor before supplying power to ply has an insulated transformer. Do not use a DC power supply with the load. an auto-transformer.
