6 Electrical connection
WARNING
CAN line - Interferences
Faulty communication due to unshielded CAN lines resulting in extreme cases in
personal injury due to malfunction of the device.
►
Connect termination resistors of 120 ohms at both ends of the CAN bus.
►
Alternatively wire the internal terminating resistor (see Pin assignment).
NOTICE
Improving electromagnetic compatibility
Improper implementation of the wiring harness may impair electromagnetic com-
patibility.
►
Keep the cables as short as possible.
►
Lay power lines and signal lines separated from each other.
NOTICE
Damages to material or functional impairment
Improper implementation of the wiring harness may cause mechanical stress.
►
Protect the cables from bending, twisting or chafing.
►
Install strain reliefs for the connecting cables.
NOTICE
Surges resulting from missing protection or fusing
Surges may cause malfunctions or damage to the product.
►
Protect the voltage inputs from surges according to the requirements.
►
Ensure that the device is handled in accordance with ESD regulations.
NOTICE
Incorrect measurement due to differences in potential
Wiring only from sensor signal to device and from supply voltage to battery can
lead to incorrect measurements due to differences in potential.
►
For accurate analog measurements, the sensor supply, sensor signal and
sensor ground must be wired together in a star configuration from the device
to the sensor.
