5.4 CAN Bus

The two wires of the CAN bus are connected to the appropriate 
terminals.

To 

Note

reduce the influence of EMI please take care that the CAN bus 

cable does not cross the wires of the signal lines.

The CAN bus line with positive potential must be connected to 
the terminal 

CAN_H

. The CAN bus line with negative potential 

must be connected to the terminal 

CAN_L

.

shield of the CAN bus may not lead into the hou-

sing and may not be connected to a terminal inside the housing. 
Cable shields have to be connected to the terminals outside the 
housing.

If you use a Sub-D connector with 9 pins (according to CiA stan-
dard), the
