supply voltage is galvanically isolated from the supply voltage for the device. The device is
supplied with voltage via the "PWR IN" connection.

Wiring the CAN interface
Framework Conditions for the CAN Interface
The SICK-specific CAN-SENSOR network is based on the CAN bus. The CAN bus is set
up in line topology.
Data transmission rate
The maximum allowable length of cable between the device and the host computer
depends on the selected physical type of the host interface and the data transmission
rate set in the device.

The required wire cross-section for the data cable depends on the total length of the
network. The table shows the overview as per ISO 11898.
