Precautions When Connecting the Power Supplies
Note
• Use Turnback Units to divide the SmartSlice I/O Terminal into two
blocks. Connect a Right Turnback Unit (GRT1-TBR) where the total
current consumption is 4 A or less. Then connect a Left Turnback Unit
(GRT1-TBL) to start a new block. Connect the Right Turnback Unit to
the Left Turnback Unit with a Turnback Cable (GCN2-100). Connect
the Unit power supply (24 VDC) to the Unit power supply terminals on
the Left Turnback Unit. Connect the I/O power supply (24 VDC) to the
I/O power supply terminals on the Left Turnback Unit.
• Add an I/O Power Feed Unit to start a new I/O power supply group.
Make sure that each group uses less than 4 A.
