ST950S Plus+ Installation and Commissioning Manual
Figure 37. PTB with 4 Way Street Cable
The power pair (Red and Blue) will be connected to the first supply column (PL15), which is also
numbered 1.
The data pair to the node (Yellow and Black) are connected to PL1 (labelled “To ByPass”). The data
pair from the node (Orange and White) are connected PL2 (labelled “From ByPass”).
In order to complete the circuit onwards to a downstream Node, a link pair (yellow and black) is
required from PL3 to PL12 (not shown).
If a second node requires connection, then the next set of connectors are used (all labelled ‘2’) and the
link pair will then be moved to link PL5 to PL12.
Terminal blocks mounted on the opposite side of the PTB bracket are available for Spur connections.
Spur connections from PTB to Node use Red, Blue, Yellow and Black wires in the Plus+ dropper cable
(Orange and White wires are unused for Spur connections). Spur wiring from the terminal block to the
remote Node uses armoured street wiring.
4.2. Stub Pole
The stub pole does not use a PTB and instead the wiring arrangement (street cable downstream and
street cable upstream) is all held within the pole and the pedestrian demand equipment itself.
