Connect the power supply wires (24 VDC) to the PROFIBUS Communication
Unit's screwless clamping power supply terminals. If pin terminals are used
on the wire ends, the pin terminals can just be inserted to wire the power.
These terminals supply power to both
the PROFIBUS Communication Unit's
internal circuits and the connected
SmartSlice I/O Units' internal circuits.
Note The GRT1-TBL Left Turnback Unit has the same screwless clamping power
supply terminals as the PROFIBUS Communication Unit. These terminals are
wired in the same way, by inserting the power supply wires.
