Notes
¾
As delivered, the brake is held together by the clamping disks on the screw threads. The
pressure springs of the brake then press on the flange via the armature plate and the ro-
tor, thus pushing it away from the stator until the flange is in contact with the clamping
disks. This "pre-tensions" the screws. Thus, the screw heads have contact with the stator
(or the flange when mounted on the housing side) before, during and, of course, after the
assembly. During assembly, only the gap between the spacers and the flange of the brake
is reduced. This gap is zero when the brake is mounted.
¾
In order to avoid tilting the armature plate during assembly, the fastening screws must be
screwed in evenly and alternately. The air gap between the armature plate and the pole
face only corresponds to s
LN
after the fastening screws have been screwed in completely.
¾
During assembly, make sure that the connecting cable for the brake is not located be-
tween the armature plate and the pole face. Otherwise, the insulation of the connecting ca-
ble would be damaged when the fastening screws are tightened and the housing closes.
¾
The connecting cable must be routed in such a way that it is ensured for all operating con-
ditions that the cable cannot be damaged by the moving parts of the brake (such as the ro-
tor or armature plate).
