of the traction cable for manual release ( ref.
3. Use XK 21 to mark the on-wall references of the holes,
as shown in Fig.4 ref.
IMPORTANT: Make sure that the hole for
routing the electric cables and the release
cable, has a diameter of not less than 20 mm
and is positioned as shown in Fig. 4 ref.
4. Secure the device on a wall;
5. Connect the electric cables coming from the
automated system to the relevant terminal-boards
of the microswitches (Fig.5) according to the type of
command:
NO = Normally OPEN
NC = Normally CLOSED
C = COMMON
ref. = EARTH cable fitting
IMPORTANT: It's forbidden to use the XK21 as

8. Using a pair of pincers, apply tension to the cable
WITHOUT RELEASING the connected OPERATOR, and
then tighten the release cable on the tensioning
device with the relevant screw;
9. Turning the head of the adjustment screw with a
hexagon wrench, move the tensioning device until
you release the operator, connected as shown in
Fig. 7 ref. ;
10. Cut excess cable at the exit of the tensioning
device;
11. If it is not present, fit the lock, conforming to standard
DIN 18252 on the front of the XK 21 device as shown
in Fig. 8;
To facilitate fitting the lock, push down
the top ends of the levers activating the
microswitches as shown in Fig. 8 ref.
12. Fasten the lock, inserted as above, with the supplied
plate and screws ( Fig.8 );
13. Join the front part to the part secured to the wall,
tightening the four self-forming screws as shown in
Fig. 9 ref. ;
14. Check activation of the microswitches, turning the key
in the lock according to the diagram in Fig.10:
A = activation of microswitch ref.
B = activation of microswitch ref.
C = detachment of release lever
IMPORTANT: Check if position C corresponds
to the disappearance of the piston
ref. in Fig.9, inside the body of the
);
device.
15. When you have checked the activation of the lock
release piston, remove the safety plug from the release
