Connecting the Turnback Units

Note
When a SmartSlice I/O System is divided into blocks to expand the system,
connect a GRT1-TBR Right Turnback Unit to the GRT1-TBL Left Turnback
Unit with a GCN2-100 Turnback Cable.
Power is not supplied through the GCN2-100 Turnback Cable. Always wire
(supply) the power to the GRT1-TBL Left Turnback Unit from the same power
supply that supplies the PROFIBUS Communication Unit.
Connect the Turnback Units with a Turnback Cable, as shown in the following
diagram. A single PROFIBUS Communication Unit can be expanded with up
to two additional blocks, connected with two Turnback Cables (2 m total).
