Installation Of The Hand Release (29) (Brake Types With Hand Release); Electrical Connection And Operation - Kendrion EEX Series Operating Instructions Manual

3.2 Installation of the hand release (29) (brake types with hand release)

Insert the hand release handle (29) into the square socket of the two cams (29.1) that are firmly fitted to the
circumference of the solenoid housing (1.1). Ensure that the handle is correctly positioned. The mechanical
release forces F and the maximum permissible release forces (actuation forces) F
Table 11/1.
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 (open) the brake
during normal operation.
Caution!
The brake torque can be neutralized manually by means of the hand release (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. 9/1) 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 release handle in its
central position (see Fig. 9/1) has been ensured.

3.3 Electrical connection and operation

Connect the spring-
applied brake to an AC
power source via
terminals 1 (BA1) and 2
(BA2) of the terminal
block (19) (see Fig. 11/2).
Connect the customer-
specific connecting cable
to the terminal block (19)
by means of a cable
gland (30) (M20x1.5). Remove the cover (26) of the
junction box (25) so that the individual strands of the
connecting cable can be connected to the terminal block
(19). The connector sleeve (30.2) of the cable gland (30)
is firmly screwed to the solenoid housing (1.1) when
delivered (see Fig. 11/1, M
(30.1) to a tightening torque of M
(clamping range 7...13 mm) and strain-relieve the
customer-specific connecting cable. After completion of
these steps, reinstall the cover (26) of the junction box
(25).
