The TxPORT 1200 RMPS can support up to three 1051 shelves (redundant five amp configuration) or up to six shelves when configured for
non-redundant 10 amp operation. All wiring connections between the 1200 and the 1051 shelf should be made using 22-gauge stranded wire,
or larger. The maximum power requirements for a 1051 shelf are 1.65 amps, -48 VDC.

To connect a 1051 shelf to the 1200, attach one end of a stranded wire to TB2 terminal 4 labeled
-48 V IN (A) on the 1051 shelf. Attach the opposite end of the stranded wire to any one of the 16
terminal connections labeled -48 VDC on the 1200. Then, attach one end of another stranded wire
to TB2 terminal 6 labeled +48 V RTN (A) on the 1051 shelf. Attach the opposite end of that
stranded wire to any one of the 16 terminal connections labeled RTN on the 1200. The -48 V and
RTN connections on the 1200 must be in parallel for safe operation. The diagram above dis-
plays a redundant power feed to the 1051 shelf. If a redundant feed is not required, you need only
connect the terminals 4 and 6 labeled -48 V IN (A) and +48 V RTN (A), respectively.
