1. INTENDED USE

The intended use of the device is the detection of changes in water level with
the help of the accessory water sensor. If the sensor comes in contact with
water the relay will switch and activate a warning signal, a solenoid valve or
start a pump. Any other use of the device is not permitted.

2. SAFETY

served, in particular VDE 0100, VDE 0550/0551, VDE 0700, VDE 0711 and
VDE 0860.
– Before opening the device, make sure that the device is disconnected from
the power supply.
– Tools may only be used on the device and/or its components, if the unit is
disconnected from the power supply and when any electric charge stored in
the components of the unit has been discharged.
– Cables and wires, with which components or device are connected, must
always be checked for insulation faults or fractures in the insulation.
– If a fault is found in the power cable, the device must immediately be deacti-
vated until the faulty cable has been replaced.
– When using components or modules the requirements, values and the de-
scription of these components for use are to be strictly followed.
– If, for a private user, the installation and the electrical requirements of the ex-
ternal components or accessories are not clear or understandable, or it Is not
clear which external devices can or may be connected to this device, consult
a trained expert for advice.
– Before installation and use, make sure that the device or module is the correct
device for the intended application and installation. If there is any doubt,
consult a trained expert or the manufacturer for advice
Please note that operation and connection errors are beyond our control. Liabi-
lity cannot be taken for consequential damages.

3. OPERATION

has been designed for wall mounting and must be mounted in such a way, that
it cannot fall down. A correctly installed 230 V mains outlet must be installed
nearby the device.
14 | Intended use
DANGER! When opening the device, live electrical components are
accessible. Make sure that you pull the mains plug out of the socket
before opening the device.
– Avoid direct water contact (spray or rain), dust and direct sunlight with the main unit.
– Electrical components do not belong into the hands of children.
– All persons using, handling, installing, servicing and maintaining this device
must be trained and qualified for handling and repairing this device and
follow this user guide!
– When used in commercial facilities, the safety regulations of the professional
trade association for electrical installations and equipment must be followed.
– The use in schools, training centres, hobby-self-help workshops and the opera-
tion of components is to be supervised by trained personnel.
– Only original spare parts may be used, if the device is in need of repair. The
use of other components can be hazardous and can cause damage.
SENSOR ASSEMBLY
Mount the water level sensors at the points that you want to monitor. Plug the RJ45
plug into the appropriate input socket of the unit. The sensor responds to water
contact at the two metal contacts. The sensor circuit is then closed. The mounting
height of the sensor defines the response point when the functions of the main unit
are activated. The sensor cable can be extended up to 25 m with a double wire.
NOTE: Install all cables securely, so that they do not become a hazard and
that they cannot be tripped over.
