    Mount the CAN-DP/2, CANopen-DP/2 module and connect the interfaces (CAN, PROFIBUS-DP, power supply voltage). Please note that the CAN bus has to be terminated at both ends! esd offers special T- connectors and termination connectors. Additionally the CAN_GND signal has to be connected to earth at exactly one point in the CAN network.
