Installation
4.1 Installation of the Presence Detector
The Presence Detector is clipped onto the FM Insert chosen. The FM Insert chosen is
installed in a standard flush-mounted box in accordance with DIN 49073, Part 1, or in the ABB
surface-mounted housing, Art. No. 6885-500.
4.2 Installation Site
When choosing the installation site, the following factors are to be taken into consideration:
- Mounting height
- Distance to controlling light source
- Objects such as movable partitions, tall flowers, etc.
- Daylight incidence
If possible, the Presence Detector should be mounted directly above the workplace in each
case. The recommended mounting height is 2.5 m. With mounting heights > 2.5 m, the
detection range increases - at the same time, the detection density and sensitivity are
reduced.
The distance to the lighting should, in the case of lamps which generate a high degree of heat,
be at least 1.5 m. High objects such as, e.g., movable partitions in open-plan offices, can
