4 Information for electrically skilled persons
4.1 Fitting and electrical connection
Fitting the device
The 110° mounting bracket ensures an optimal mounting position at all times for mounting on
vertical walls. The mounting bracket can be installed on a mast using the supplied clamp.
o
Mount the precipitation sensor in such a way that rain can reach it in an unobstructed
manner.
Connecting the device
DANGER!
Electrical shock when live parts are touched.
Electrical shocks can be fatal.
Before working on the device, disconnect all the corresponding miniature
circuit breakers. Cover up live parts in the working environment.
Connected to the precipitation sensor are two PVC hose lines with numbered wires.
Control cable (4)
Wire 1: NC contact
Wire 2: centre contact
Wire 3: NO contact
Figure 2: Example for connection of precipitation sensor to blind/shutter controller (6)
o
Connect mains cable (3) and control cable (4) of the precipitation sensor (5) as shown in
the connection example (Figure 2). Wire 3 of the control cable should be connected to the
outer conductor so that no voltage is present on the free wire 1.
i
The change-over contact can be used for either 230 V or for safety extra-low voltage.
