Figure 30. CTB Street Terminations to Nodes
Figure 31. CTB Street Termination Detail
shows the function of the terminals. The arrows are coloured to indicate the
conductor colours of connected cables (in the above example two cables).
The +48V and 0V carry power to the nodes, whereas the D+ and D- carry the RS485 data
communications.
3.15.5. CIC/CTB Interfaces: 48V Power In
With reference to
the incoming 48V from the Redundancy Modules is
terminated to the Faston terminals on the CTB. The black 0V wires terminate to the GND terminals,
and the Orange wires terminate at the Power Bank terminals.
In addition, the Redundancy module also provides power supply monitoring signals to the CTB,
terminated at PL3 “48V PSU MON”, with the following pin connectivity:
