6.3 Electricity Supply via Slip Ring
For applications where the PacDrive PD-8 and PacDrive SCL-055
are installed on a turning machine rack (rotary), it is possible to use
a slip ring to supply electricity to the components on the rotary rack.
The following connection proposal shows the connection plan for
the power cable and data cable.

The colors above can be different in practice, as they are not
standardized.
For the Tx and Rx lines, use the respective pairs of leads in the
Cat7 cable.
Pairs that belong together can be identified by their twisting and
common shielding.

NOTE:
Not needed wires stay open!
Between the power connection (DC+ / DC-) and all the other cables, a
"safe disconnection" according to EN50178 must be observed.
