Installation

3.If you have one input power cable and one

± 48 Vdc power source, plug the input power cable to either the ±48VDC A connector or the ±48VDC B connector. See Figure 2-5. (The option strap settings for this power option are listed in Table 2-4.)

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.

(The option strap settings for this power option are listed in Table 2-5.)

If you have two power cables and two separate

±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. (The option strap settings for this power option are listed in Table 2-5.)
