Wiring
ƒ Only use cables which correspond to the listed specifications, see ( ^ 48).
ƒ Provide connection to the controllers by means of the bus connector. The bus system
will not be interrupted if the bus connector is removed from the controller.
ƒ Observe the notes and wiring regulations given in the documentation for the control
system.
ƒ Adapt baud rate to the bus cable length.
ƒ Check bus terminating resistors and activate them if necessary.
