CAN bus termination for CAN- (for bus termination,
Term- must be connected with CAN-)

Term-
CAN bus termination for CAN- (connecting alterna-
tive for terminal 1.6)
1.8

CAN-GND
Ground potential of the CAN bus
At the line ends of a bus segment, terminating resistors must be connected. If TU517 or TU518
is used, the bus terminating resistors can be enabled by connecting the terminals Term+ and
Term- to the data lines CAN+ and CAN- (no external terminating resistors are required, see
figure below).
The following figures show the different connection options for the CANopen communication
interface module:
