5.1 Enable zone
The outputs (OSSD) are only enabled when a damping target is present in the
enable zone� Outside this enable zone the outputs remain switched off�
If damped with a standard target plate of 18 x 18 x 1 mm made of FE360 (= mild
steel) and flush installation to IEC 60947-5-2 the enable zone is in the range of
≤ 1 ��� ≥ 5 mm�
The safe switch-off distance s
ar
is > 7 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�

* Typical values for damping with a reference target plate of 18 x 18 x 1 mm and flush
installation to IEC 60947-5-2 at an ambient temperature of 20°C�
