The OccuSwitch can be installed with either
conventional wiring or Wieland connectors. For
the second option, the Wieland cable (LCC1070) is
required. The OccuSwitch comes with a detachable
mains connector for easy installation. This connector
is removed if the Wieland cable is used. The mains
connection is protected by a retractable cover and
secured with a tie wrap.

Note
The connector of the OccuSwitch is capable of
accepting a wide range of cables (1.5 to 2.5mm
2
),
but when heavy ridged cables (especially single
core) are used it is strongly advised to make use of
the LCC1070 to prevent the OccuSwitch of being
pushed out of the ceiling due to the weight of
these ridged cables.
Parallel operation
Parallel operation is used to enlarge the covering area
of the OccuSwitch. This can be done in two ways;
either by parallel installation or by using the parallel
connection of the advanced OccuSwitch (LRM1080).
Parallel installation limits the total load to 6A and
restricts the application to one mains group. For
parallel connection the LRM1080 uses a bus signal to
indicate movement detection to other units. All units
can be used up to 6A each and with several mains
groups (or even phases). A short delay between the
different units during switch-off may occur. Max. 10
LRM1080 in parallel.
