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.
