Always secure the Slice I/O Terminal on the DIN Track by installing End Plates
on both sides of the Terminal. First hook the bottom of the End Plate on the
bottom edge of the DIN Track (1), attach the top of the End Plate, and pull the
End Plate down onto the top edge of the DIN Track (2).
Tighten the End Plate's securing screw.

Always secure the Slice I/O Terminal by attaching End Plates on both ends.
Both the Slice I/O Terminal power supply and the external I/O power supply
are connected with screwless clamping-type terminals on the Communica-
tions Unit.
The Communications Unit has two sets of power supply terminals for the fol-
lowing two systems.
Power supply
terminals
Unit power supply These terminals supply power to the Communications Unit's
terminals internal circuits as well as the connected Slice I/O Units' inter-
nal circuits (supplied through the Slice bus).
I/O power supply ter- These terminals supply power to the external I/O that is con-
minals nected to the Terminal's Slice I/O Units.
The maximum power consumption for a Slice I/O Terminal is 80 W per block.
1. Calculate the power consumption of all of the Slice I/O Units connected to
the Communications Unit.
2. If the power consumption exceeds 80 W, mount a Right Turnback Unit
(GRT1-TBR) on the Slice I/O Unit at the point where the power consump-
tion is less than 80 W.
3. Connect the 24 VDC Unit power supply to the Left Turnback Unit (GRT1-
TBL).
