[. . . ] (For further information on connecting several units contact KEYENCE) Placing the amplifier cable together in the same conduit with power lines or high voltage lines may cause detection errors due to interference or sensor damage. For this reason, always isolate the amplifier cable from these lines. If using a commercial switching regulator, make sure to ground both the frame ground terminal and ground terminal. Do not use the LV Series outdoors, or in any location where extraneous light can directly enter the light receiving surface. [. . . ]
