CANopen field bus
For CANopen, only bus cables with characteristics as recommended in ISO 11898 are to be
used. The requirements for the bus cables depend on the length of the bus segment. Regarding
this, the following recommendations are given by ISO 11898:

NOTICE!
Risk of telegram and data errors!
The use of wrong cable type and quality could lead to limitations in cable length,
causing telegram and data errors.
NOTICE!
Risk of damaging the terminating resistor!
A bus-line short-circuit to the 24 V DC power supply can cause damage by
exceeding the power rating of the terminating resistor.
