4.2 DC Connection
The outputs from the rectifier modules are wired from the backplane PCBs and commoned together on busbars.
Connection is by two 8mm studs, pitched at 25.4mm, on each busbar. A suitable double hole lug is
recommended.
4.3 Signals Interface
The signals from each rectifier are connected via ribbon cables from each backplane PCB on to a common node
card inside the shelf. There are two external interface connectors on this card, one 20 way connector (PL6) for
use with the APC DM2000 power monitoring system, and a 26 way General Interface connector with a different
set of general purpose signals (PL5). These connectors are illustrated in figure 5.1 overleaf and their pin out is
given in table 4.2 below.
Customer connection to the General Interface PL5 should use connector type: polarised 26way female socket
connector with 2.54mm x 2.54mm pin centres and strain relief e.g. Thomas & Betts part number 636-2641.
