Connecting the power supply cable to the vehicle electrical system
Connection of the Sitraffic Sensus Unit power supply cable to the vehicle electrical
system (as shown in the related figure) has to be done by authorised staff only!
Working on a vehicle (and especially on a vehicle electrical system) can cause danger.
All work must be carried out by authorised staff!
Always observe the instructions and recommendations of the vehicle manufacturer when
working on a vehicle electrical system!
Connecting the Sitraffic Sensus Unit to the external power supply cable
1. Remove the connector panel cover of the device.
2. In case of already mounted cable for temporary
installation: Make sure that the cable is not connected
to the vehicle electrical system and that the plug’s snap
catch is released when pulling out the connector of the
power supply cable.
3. Plug the provided power supply cable into the power
socket and make sure that the plug’s snap catch has
engaged.
4. Make sure that the corrugated tube of the provided
power supply cable is located at the right position.
5. Close the device again with the connector panel cover.
Danger of fire and malfunction!
Always protect the power cable against mechanical forces
and other negative factors (e.g. extensive heat, aggressive chemicals) which could lead to
destruction of isolation and short circuits. Replace damaged cables immediately!
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.
