Power Supply Do not impose an excessive voltage on the E2A3, otherwise it may be damaged. Do not impose AC current (100 to 240 VAC) on any DC Model, otherwise it may be damaged. Load Short-circuit Do not short-circuit the load, or the E2A3 may be damaged. The E2A3’s short-circuit protection function will be valid if the polarity of the supply voltage is correct and within the rated voltage range. Wiring Be sure to wire the E2A3 and load correctly, otherwise it may be damaged. Connection with No Load Be sure to insert a load when wiring. Make sure to connect a proper load to the E2A3 during operation, otherwise it may damage internal elements. Do not expose the product to flammable or explo- sive gases. Do not disassemble, repair, or modify the product. Precautions for Correct Use Designing Power Reset Time The Proximity Sensor is ready to operate within 100 ms after power is supplied. If separate power supplies are connected to the Proxim- ity Sensor and load, be sure to supply power to the Proximity Sensor before supplying power to the load. Effects of Surrounding Metal When mounting the E2A3 within a metal panel, ensure that the clearances given in the following tables are maintained. (Unit: mm) (Unit: mm) * Using the nuts provided with the E2A3 allows mounting in the way shown be- low. Power OFF The Proximity Sensor may output a pulse signal when it is turned OFF. Therefore, it is recommended that the load be turned OFF before turning OFF the Proximity Sensor. Power Supply Transformer When using a DC power supply, make sure that the DC power sup- ply has an insulated transformer. Do not use a DC power supply with an auto-transformer. Mutual Interference When installing two or more Sensors face-to-face or side-by-side, ensure that the minimum distances given in the following table are maintained. (Unit: mm) This product is not designed or rated for ensuring safety of persons. Do not it for such purposes.

If there is a power or high-tension line near the cable of the Proximity Sensor, wire the cable through an independent metal conduit to pre- vent against Proximity Sensor damage or malfunctioning. Cable Extension The standard cable length is less than 200 m. The tractive force is 50 N. Mounting The Proximity Sensor must not be subjected to excessive shock with a hammer when it is installed, otherwise the Proximity Sensor may be damaged or lose its water-resistance. Do not tighten the nut with excessive force. A washer must be used with the nut. Maintenance and Inspection Periodically perform the following checks to ensure stable operation of the Proximity Sensor over a long period of time. 1. Check for mounting position, dislocation, looseness, or distortion of the Proximity Sensor and sensing objects. 2. Check for loose wiring and connections, improper contacts, and line breakage. 3. Check for attachment or accumulation of metal powder or dust. 4. Check for abnormal temperature conditions and other environ- mental conditions. 5. Check for proper lighting of indicators (for models with a set indi- cator). Never attempt to disassemble or repair the Sensor. Environment Water Resistivity The Proximity Sensors are tested intensively on water resistance, but to ensure maximum performance and life expectancy, avoid immer- sion in water and provide protection from rain or snow. Operating Environment Store and operate the Proximity Sensor only within the given specifi- cations. Inrush Current A load that has a large inrush current (e.g., a lamp or motor) will damage the Proximity Sensor. Connect the load to the Proximity Sensor through a relay.
