If you have two input power cables and one

±48 Vdc power source, plug one input power cable to the ±48VDC A connector and the second input power cable to the ±48VDC B connector. Then, connect both input power cables to your single ± 48 Vdc power source. See Figure 2-7.

±48 Vdc power sources (e.g., Source A and Source B), plug one input cable from a ± 48 Vdc power source (e.g., Source A) to the ±48VDC A connector. Plug an input power cable from a different ± 48 Vdc power source (e.g., Source B) to the ±48VDC B connector. See Figure 2-6.
