When a value of zero is given, the calculation of the minimum distance, S, should be made in accordance with chapter
3.3 Calculation of Minimum Distance for Installation, calculation point a).
NB! Electrosensitive protective equipment with a height of the:
–
upper edge of the detection zone below 900 mm is not included since they do not offer sufficient protection against
circumventing or stepping over
–
lower edge of the detection zone above 300 mm in relation to the reference plane does not offer sufficient protec
-
tion against crawling below.
a Approach to the hazard zone by reaching over is impossible
NB!
Values shall not be interpolated. Use nearest safer value.
