Note
8UD with illumination
The lock hasp diameter of 3 mm is only required when the illuminated version of the 8UD is
used.
Note
Shaft positioning
You will find the assignment of the center hole in the cabinet door (shaft) to the position of
the 3KF switch disconnector in the cabinet in the dimensional drawings of the 3KF. See
chapter Drilling templates (Page 116).
The clearance between the center hole in the cabinet door (shaft) and the hinge of the
cabinet door must be at least 80 mm.
Note
Hinge clearance
The smaller the hinge clearance compared with the total width of the cabinet door, the
smaller the force required to prevent unintended opening of the cabinet door while the switch
disconnector is in the closed state.
We therefore recommend increasing the hinge clearance to at least 1/3 of the total width of
the cabinet door.
