In case of installation near power lines, the detector units should be placed no closer than 16.40 ft.
(5 m) to lines of a voltage up to 35 kV, and no closer than 32.81 ft. (10 m) to lines of a higher
voltage up to 500 kV. It is also recommended that, if practical, any cabling connected to the
detector units be buried underground in such circumstances.
Note: If the above requirements are not strictly observed, the operating performance of the
detector may not be optimal. In the absence of such compliance with said requirements, the
determination of whether the continued use of the detector under the existing conditions is
appropriate should be dictated by the actual performance experienced.
