4 Electrical connection
4.1 Wiring
Pin connection (→ 5 Technical data)
If a prewired connection cable is used, remove the cores with unused signal
inputs and outputs.
Unused cores, in particular core loops, lead to interference coupling that
can influence the connected controller.
4.2 Ground connection
To ensure the protection of the device against electrical interference and the
safe function of the device, the housing must be connected to the ground of
the vehicle.
1: Drill hole for ground connection
► Establish a connection between the device and the ground of the vehicle using
M5 screws.
Screws to be used (→ 3.1 Fixing)
4.3 Fuses
► The individual electric circuits must be protected in order to protect the whole
system.
Designation
Supply voltage sensors/module
Supply voltage outputs
Supply voltage via relay
4.4 Laying the supply and signal cables
► Basically all supply and signal cables must be laid separately.
► Screen signal cables in EMC critical applications.
