Operation- and
Assembly Instructions
1 Safety instructions
Electrical equipment may only be installed and fitted by electrically skilled persons.
Failure to observe the instructions may cause damage to the device and result in fire and
other hazards.
Danger of electric shock. Risk of injury from automatic movement of blinds/shutters.
Always disconnect before carrying out work on the devise or load.
Danger of electric shock. Insulate unused wires.
Risk of injury from hot surfaces. The integrated heater can cause the sensor surface to
reach high temperatures. Do not touch the sensor surface.
The sensor surface is delicate; protect it when handling the device. Clean the sensor
surface only with mild cleaning agents. Sensor surface can be damaged.
These instructions are an integral part of the product, and must remain with the end
customer.

- Integrated heater speeds up the drying of the sensor surface and melts snow and ice.
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.
