4.8 Coupling with motor drive UEMC 41
Description of drive, coupling and adjustment can
be found in a separate manual enclosed to the
UEMC 41 drive.
Additional information:
Depend on application and version of drive one of
the following exemplary coupling need to be done.
General requirements for assembly:
– the disconnector must be correctly installed on
the supporting structure on the wall
– the NRK2/1 bevel gear must be mounted on the
shaft of the disconnector (or shaft extension)
and fixed by tightening screws on its housing
– connection rods need to be cut to the appropri-
ate length and a hole ø10 must be drilled for
fixing in the cardan joint, rod connectors or bevel
gears
– all connections should be secured with ø10 bolts
and cotters or by tightening the screws.

Drive on the front door, connection at 90° angle
The support [pos. 7, Fig. 7] together with fixed
inside bevel gear [pos. 6, Fig. 7] should be mount-
ed in a way that the axis of the smaller wheel
coincides with the axis of the smaller gear on the
disconnector shaft. The axis of the output shaft of
the drive should lie in the axis of the larger wheel
of the bevel gear.

shaft
The drive should be mounted on the right side of
the disconnector so that closing the disconnector
is clockwise. Coupling the drive shaft with the dis-
connector is done with two intermediate elements.
