9. Establish the electrical connection and energize the brake (
10. Use a torque key to re-tighten the supplied fixing screws (10) with the required tightening torque
( 16).
11. Switch off the power.

12. Check the air gap using a feeler gauge and correct it if necessary (s
Figures 11 and 12.
4.5.4 Setting the manual release
Carry out steps 13 and 14 separately for each side of every lever
13. Tighten the lock nuts (pos. 12.8) on the clips (12.11) evenly until the nuts of the tension rod are in contact
with the armature plate of the second stator (1A) (there should be noticeable resistance). While tighten-
ing, make sure that the clips (12.11) are parallel to the rear of the stator (1A). (Check using a caliper
gauge.) If there are dimensional differences where X > 0.1 mm (see Figure 19), this should be corrected
by loosening the lock nut (12.8) at the smaller dimension and tightening the lock nut (12.8) at the larger
dimension until the clips (12.11) are adjusted in parallel to the back of the brakes (as shown in Figure
19).
14. Evenly tighten the lock nuts on the motor end shield side up to the point where the nuts of the tension
rod are in contact with the armature plate of the first stator (1) (tangible resistance).
15. Loosen the lock nuts (12.8) at the clips (12.11) by a ¾ revolution (270°).
Carry out steps 16 and 17 separately for each side of every lever.

NOTICE
For setting the manual release, always lock the pre-assembled hexagon nut of the tension rod
(12.14) against rotation and rotate the lock nuts at the ends of the tension rod only.
