-The 3.2 mm recess is for preventing rotation and is not necessary when a nameplate
or anti-rotation ring is not used.
-When using the safety lever lock, determine the vertical spacing in consideration
of convenience for installing and removing
the safety lever lock.
-Recommended vertical spacing: 100 mm
-The minimum mounting centers are
applicable to switches with one layer of
contact blocks (two contact blocks). When
two layers of contact blocks are mounted,
determine the minimum mounting centers
for ease of wiring.
