CAUTION!
The Litz wires [1] [2] for the temperature sensor and the encoder
must not be damaged or crushed. The Litz wires have only small excess length.
Remove the encoder cover carefully. To reduce the stress on the Litz wires, it is
recommended to temporarily attach the encoder cover to the drive (see following
figure).

5. Insert the stud (for information on sizes and tightening torques, refer to chapter
"Recommendations for studs" (→
99)) into the holes of the manual brake re-
lease [3] of the brake.
6. Connect the brake to the voltage supply.
7. Release and apply the brake electrically. Measure the motion ΔH of the pressure
plate at the studs. This motion ΔH corresponds to the working air gap.
8. If the dimension ΔH is >
0.6 mm
, the brake lining carrier or the brake must be re-
placed. The working air gap cannot be adjusted.
9. Remove the studs from the holes of the manual brake release [3].

Important!
Check the Litz wires [1] [2] for possible damages.
