3.2 Installation of the hand release (29) (brakes types with hand release)
The lever of the hand release (29) must be inserted into the square socket of the two cams (29.1) which are
firmly fitted to the circumference of the solenoid housing (1.1). Make sure the lever is correctly positioned.
The mechanical release forces F and the maximum permitted release forces (actuation forces) F
max
are
specified in Table 8/1.
Note!
Machinery-specific regulations and requirements (e.g. for hoists, cranes and elevators) must be observed
when using brakes with hand release (29). The hand release (29) must not be used to release the brake
during normal operation.
Caution!
The brake torque can be neutralised manually by means of the hand release feature (29). Consequently, the
brake must be installed in such a way that any unintentional actuation of the hand release (29) is excluded
and reliable brake operation is ensured.

Warning!
Check that the mechanical hand release (29) is in a central position (see Fig. 6/1) when not in use. This is
crucial to ensure reliable brake engagement. Otherwise, the full braking effect of the spring-applied single-
disc brake may not be reached. In this case, the machine (e.g. motor) must be stopped immediately and
must not be restarted until correct operation of the hand release (29) and automatic return of the hand
release lever in its central position (see Fig. 6/1) has been ensured.
