Coding & Wiring Details: Connector PL5 is a 20-way Berg connector that has a
side flange coding element, which mates with the
associated slot of the IDC board mounted 16-way
connector. The pin positions 1, 2, 19 & 20 on the Berg
connector are not used for wiring purposes but are used
to provide a stop for the IDC board mounted connector
locking levers. See the following diagram:

Instead of driving all the signals at the 230V nominal supply, the ST750 is capable
of driving the Wait indicators or all the pedestrian phase signals directly with an ELV
48V lamp supply.
Switching the supply from 230V to 48V requires fuses and links on the lamp switch
card to be re-arranged as detailed in Section 5.13. The required arrangement also
