5 Information for electricians
5.1 Installation and electrical connection
DANGER!
ç
Touching live parts in the installation environment can result in
an electric shock.
The device could get damaged!
Disconnect the connecting cables before working on the device
and cover all live parts in the area!
Selecting installation location
As a display and operating panel, the device should be mounted in a place
that is easily accessible. The user habits are decisive when determining the
installation height. We recommend an installation height of approx. 1.50 m.
Direct sunlight or powerful light sources could impair the proximity sensor.
Connecting and installing the device
Observe the layout requirements for SELV installations.
To avoid EMC interference, do not lay input cables parallel to mains ca-
bles.
„ Fasten the enclosed supporting ring (12) over the oblong-shaped holes
onto at least 2 opposing screw domes of the wall box.
Alternatively, the supporting ring has 4 additional fi xing holes for
other mounting systems.
„ Guide the bus and auxiliary cable out of the wall box.
The second wire pair (yellow/white) of the KNX bus coupling unit may be
used for connection of auxiliary voltage.
„ Connect the bus cable via the connecting terminal (6). Be sure that the
polarity is correct.
„ Connect auxiliary voltage using a connecting terminal (7) independent of
polarity.
After connecting the operating voltage, the device initialises itself for a few
seconds. Message
device cannot receive any information via the KNX bus during this time.
If the device should also be used for temperature control, lay an external
temperature sensor (see Accessories) in a ductwork and guide out the sensor
head at the measurement point.
