Figures 8 and 9 illustrate the individual conductor connectivity for attaching the ABB protective relays in the
DPU/TPU/2000 and the DPU/TPU/GPU 2000R. It is important to note that Figures 8 and 9 illustrate only the
attachment of each device terminal. EACH NODE MUST BE DAISY-CHAINED AS ILLUSTRATED IN FIGURES
4 THROUGH 7.

If an ABB relay uses a TYPE 8 card, COM PORT 3 is actually an RS 485 port presented in a DB 9 format. The
Pin designation is presented in Table 1 and lists the cross listing for the AUX COM connector present on the
2000R product and 2000-product line. As illustrated in Figures 7 and 8, the AUX COM PORT connections are
given. If one is installing RS 485 on a TYPE 8 card, both the AUX COM PORT and COM 3 have RS 485
connectivity available.
