Wiring

• The ends of the bus lines must be terminated between CAN_L and CAN_H for each physical bus
segment (see figure 9.9
• Typical CAN cables consist of a twisted-pair cable with a shield that is usually used as CAN_GND.
Only use cables recommended for DeviceNet or CANopen.
• The ground reference CAN_GND must only be connected to earth potential (PE) at one place on a
physical bus segment (see figure 9.9).
