Close the cabinet door carefully the first time to check correct alignment between the 8UD
handle and the 3KF switch.
NOTICE
Material damage
Risk of damage to the device.
When the cabinet door is opened, the 8UD coupling head is deflected slightly downwards.
This deflection is caused by tolerances between the 8UD shaft and the mounting point on
the 3KF, as well as by tolerances between the 3KF and the mounting plate or standard
mounting rail in the cabinet.
In the usual applications, the taper on the rear plate of the handle ensures that the coupling
head engages in the handle even in the event of deflection.
If the 3KF is mounted on standard mounting rails and shafts that are longer than 300 mm,
the deflection of the coupling head may be so great that the cabinet door cannot be closed
or the 8UD may be damaged. In this case the 8UD shaft can be supported by an internal
structure of the cabinet (to eliminate deflection) or the accessory "shaft jack" for 8UD can
be used. See chapter Accessories for 8UD (Page 103)
