e3g-l1/l3 e3g-l1/l3 17 precautions j designing high-voltage lines do not place sensor power supply or signal lines within the same conduit as high-voltage power lines. voltage ratings do not exceed rated supply voltage, ripple percent (for dc models), or load current limits. ambient lighting do not install the sensor in direct sunlight or other sources of strong ambient light. environmental conditions do not install the sensor in areas $ with high humidity, or where condensation would result $ with corrosive gas. $ with high vibration or shock. power supply if a switching power supply is used, or when using an inverter or servomotor, you must ground the fg (frame ground) and g (ground) terminals on the power supply for proper operation and to avoid damaging the sensor. water exposure although conforming to ip67, do not use the sensor where it may be immsersed, is outdoors, or is exposed to rain. to ensure the water resistance of the sensor, tighten the screws of the operation panel cover to a torque of 0.2 to 0.3 n s m. cable $ the bending radius of the cable should be at least 25 mm. $ when using extended power and signal cable, total length must not exceed 100 m, with a minimum wire size of 0.3 mm 2 (22 awg). $ do not apply tensile force exceeding 50 n to cable (pre- leaded and connector models). avoiding malfunctions if using the photoelectric sensor with an inverter or servomotor, be sure to ground the fg (frame ground) and g (ground) terminals, otherwise the sensor may malfunction. proper mounting screws use m3 screws and washers to mount the sensor and bracket. mechanical shock avoid mechanical shock during installation which may amage the housing (see shock specifications) short--circuit protection if the load short--circuits, the output will be turned off. disconnect power and check the wiring. after correcting the shorted condition, turn power back on. the sensor will reset the short-circuit protection function. the short-circuit protection is activated when the current flow is at least 2.4 times the rated load current. when using an inductive load, the inrush current must not exceed this factor. connector $ when connecting or disconnecting the connector, hold the connector cover to avoid tension on the housoing. $ tighten the connector by hand only. do not use tools which may damage the connector. $ always disconnect power before connecting or disconnecting the connector. $ be sure that the connector is tightened securely. the sesnor enclosure rating may be reduced or the connector may get loosened. j maintenance and in spection cleaning $ solvents damage the casing of the sensor. do not use solvents to clean the sensor. eeprom writing error $ if a teaching data error occurs with the operation indicator flashing due to a power failure or static noise, perform the teaching operation of the sensor again.
