handle was locked in the OFF position, the 3KF switch disconnector cannot be closed and
the cabinet door cannot be opened. Door interlocking cannot be overridden.
The rotary operating mechanisms can be locked with up to three padlocks with a shackle
diameter of 4.5 to 9.5 mm. The padlocks are not included in the scope of supply.

Enabling interlocking in the ON position

8UD handles can be modified in a way to allow interlocking in the OFF and ON position.
Note
• This modification is not reversible.
• Enabling of interlocking in the ON position is only possible as long the handle has not
been mounted on the cabinet door. If you want to enable interlocking in the ON position,
please take care to do so before installation of the handle.
Remove the operating lever from the front cover.
