with a hexagon socket head screw (4) and a washer (3) to the shaft stump.
2. Insert the plastic washer (5) in the rotary magnet (6) and snap the rotary magnet

3. Push the clamping ring (7) over the rotary magnet (6) so that the spring elements
(7a) are opposite the hook (6a) on the rotary magnet and snap in. The clamping
ring and the rotary magnet are now hard to turn.

between the top edge of the rotary magnet and the top edge of the console is set
automatically to 3 mm.
5. If you use a console which deviates from the standard, you have to leave
appropriate space underneath the NCS with a suitable extension for the shaft
stump or washers.
