The GRT-PNT PROFINET IO Communication Unit has two sets of power
supply terminals. See section 2-1-6 Power supply connector.
The following wiring example shows how power can be supplied to the various
units in the SmartSlice I/O system.

The maximum power consumption for SmartSlice I/O Units is 80 W per block.
1,2,3... 1 Calculate the power consumption of all SmartSlice I/O Units connected to
the PROFINET IO Communication Unit (including other Units like Turnback
Units and End Unit). Refer to the GRT1 Series SmartSlice I/O Units
Operation Manual (W455) for the power value for each SmartSlice I/O Unit.
2 If the power consumption exceeds 80 W, mount a Right Turnback Unit
(GRT1-TBR) on the SmartSlice I/O Unit at the point where the power
consumption still is less than 80 W.
3 Connect the 24 V

Note 1 The GRT1-TBL is equipped with separate power supply terminals for the Unit power
supply and I/O power supply.
When dividing the supply power, always wire (supply) the power from the

same power supply, as shown in the wiring example above.
