Use these cables!
It is important not to exceed the maximum bus length 12 m, that is, the total length of the cables
used may not exceed 12 m.
Check that a plug-in termination unit DSTC 176 is located only on the last bus extender slave
board in the chain. See Figure 2-20.
Electric Installation
Make use of the enclosed ribbon cables to interconnect the bus between the cabinets. Such a
cable is connected at one end and temporarily wound up and hung up on the wall side.
Figure 2-20 shows an example of a non-redundant installation. The actual ribbon cables are
illustrated with a thick line.
Since no intermediate side walls or plates are used on a cabinet within a row, draw the ribbon
cables directly between the cabinets.
The ribbon cables are sensitive to interference. Locate them at least 100 mm away from other
cables and wires in the cabinet.
Ensure that there is no tension in the wiring, especially with respect to possibly swinging the
hinged subframe for I/O subracks.
Carefully fix the ribbon cables to fixing bars or the like with the help of cable straps.
