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.
Precautions for Correct Use
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 EtherCAT
Communication Unit.
Connect the Turnback Units with a Turnback Cable, as shown in the following diagram. A single
EtherCAT Communication Unit can be expanded with up to two additional blocks, connected with two
Turnback Cables (2 m total).
