13.1.3. IP20 terminating circuit
When installing a CANopen system, ensure that the terminating circuit of the data lines is correct. The circuit pre-
vents the occurrence of interference caused by signal reflection in the data lines. The trunk line must be terminated
at both ends with resistors of 120 Ω each and 1/4 W power loss.
For the IP20 variant a terminal resistance of 120 Ohm between the two bus connections CAN High and
CAN Low can be added using a bridge in the 9-pole D-SUB field bus connection between pin 4 and pin 8.
