17 e3x e3x 17 correct connection do not pull or press the fiber units. the fiber units have a withstand force of 1 kg or 3 kg (pay utmost attention because the fibers are thin). do not bend the fiber units beyond the permissible bending radius. do not bend the edge of the fiber units. incorrect do not apply excess force on the fiber units. 40 mm max. amplifier fiber unit 20 mm max. fiber unit nylon wireholder metal holder the fiber head could be broken by excessive vibration. to prevent this, the following is effective: a one-turn loop can absorb vibrations tape mounting 1. mount the front part on the mounting bracket (sold together) or a din rail. 2. press the back part onto the mounting bracket or the din rail. removal by pulling back the lock (yellow) on the bottom with a flat blade screwdriver, the amplifier can be removed with ease. in the case of side mounting, attach the mounting bracket on the amplifier first, and secure the amplifier with m3 screws and washers. the diameter of the washers should be 6 mm max. others when power is off: the moment power is turned off, the e3x could output a pulse signal which could affect the operation of the devices connected to it. this will happen more often if power is supplied to the e3x from an external power supply, thus affecting the connected timer and counter. use a built-in power supply as much as possible to avoid this. if power is supplied to a photoelectric sensor through a cord that is wired together with other power lines in the same duct, the cord will be influenced by the power lines and malfunctioning of the photoelectric sensor or damage could result. wire the cord separately or use a sealed cord to supply power to the photoelectric sensor. if the case of the cord is extended, use a wire with 0.3 mm 2 max.. the total length of the cord should be 100 m max. power supply: if a standard switching regulator is used as a power supply, the frame ground (fg) terminal and the ground (g) terminal must be grounded, or otherwise the e3x can malfunction, influenced by the switching noise of the power supply. the supplied voltage must be within the rated voltage range. unregulated full- or half-wave rectifiers must not be used as power supplies. do not use a hammer to hit the amplifier when mounting or the amplifier will loose watertightness. amplifier units correct incorrect power line din rail washers (6 dia. max.)
