ENGLISH
When using the suction cups you must check for correct fitting before each journey.
The service life of the suction cups is typically 6 months if the suction cups are used on
the windscreen.
Assembling the device and its holder
1. Close the gap between the Sitraffic Sensus Unit and holder until you hear a clicking
sound.
2. Check the connection by trying to tear apart the holder and the Sitraffic Sensus Unit.
Connecting the Sitraffic Sensus Unit to the external power supply
Connect the Sitraffic Sensus Unit power supply cable for temporary installation to the
cigarette lighter socket (or DIN socket) as shown in the figure.
It is recommended to use the DIN socket to plug in the cigarette lighter connector of the power ca-
ble. The DIN socket in the vehicle is recognizable by the smaller diameter of the socket compared to
a conventional one. To use this socket you have to remove the red cap of the connector by twisting
it to the left. Then plug the cigarette lighter connector into the DIN socket.
Don't remove the red cap if you use a conventional cigarette lighter socket. You can immediately
plug the cigarette lighter connector into the cigarette lighter socket.
The Sitraffic Sensus Unit may only be connected to voltages of between 8 and 32 V DC.
Ignoring this warning could lead to serious damages of the device and will cause a decline
of guarantee claims.
Fix the power supply cable in such a way that it cannot become disconnected while driving
the vehicle or otherwise negatively affects the vehicle operation.
