4-4
Precautions When Connecting the Power Supplies
There are limits for each block to the capacities of the power supplies. The
total power consumption of the CompoNet Communications Unit and Smart-
Slice I/O Units must not be larger than 80 W. The total current consumption of
the I/O devices which connect to the SmartSlice I/O Units must not be larger
than 4 A.
If the current consumption or power consumption is too large, do the proce-
dure below.
Total Unit Power Consumption
1,2,3...
1. Refer to
Appendix D Power Consumption and Weight Tables
and calculate
the total power consumption. Include the CompoNet Communications Unit
and the connected SmartSlice I/O Units.
2.
If the total power consumption is larger than 80 W, connect a Right Turn-
back Unit (GRT1-TBR) where the total power consumption is 80 W or less.
Then connect a Left Turnback Unit (GRT1-TBL) to start a new block.
3.
Connect the Right Turnback Unit to the Left Turnback Unit with a Turnback
Cable (GCN2-100).
4.
Connect the Unit power supply (24 VDC) to the Unit power supply termi-
nals on the Left Terminal Block. Connect the I/O power supply (24 VDC) to
the I/O power supply terminals on the Left Terminal Block
Total I/O Current Consumption

1.
Refer to
Appendix E Total I/O Current Consumption Table
and calculate the
total current consumption of all connected SmartSlice I/O Units. Include
the Turnback Unit.
2.
If the total current consumption is larger than 4 A, do one of these proce-
dures:
