Installing the lock
At tention!
Prevent the door from closing accidentally: In the case of products with the suffix SV, the lock automati-
cally locks a closed door and can then only be unlocked again using the locking cylinder.
· Install a locking cylinder before closing the door with the lock installed.
1 Screw the lock into the lock recess.
2 Attach the lock fittings.
3 Check that the lock can be operated easily.

The lock is ready to use once the strike plate is assembled.
Installing the strike plate
The strike plate must be installed in the door frame in such a way that the lock latch and trip latch can
slide over a flat surface (“Profiles with thermal separation”, page 46). The trip latch must remain
depressed throughout this movement.
1 Create the strike plate recess and all drill holes.
2 Clean the strike plate recess and all drill holes by blowing out or vacuuming.
3 Screw the strike plate that matches the lock being installed into place.
