5.1 Enable zone
The output is only enabled when damped in the enable zone� Outside this enable
zone the output remains switched off�
If damped with a standard target plate of 60 x 60 x 1 mm made of FE360 (= mild
steel) and non-flush installation to IEC 60947-5-2 the enable zone is in the range
of 10���20 mm�
The safe switch-off distance s
ar
is > 35 mm�
The enable zone is different if damping elements which deviate from the standard
target plate in terms of material, form and size are used�
