To connect the DC input feeds to the BIP:
1 Locate the DC power source for the DC input feed.
2 Determine the power requirements for your configuration (see Figure 35 on
page 53 ).
3 Locate the A and B -48 VDC input feeds ( Figure 36 ).
The -48 VDC input feed cables should be tagged with source labels (for
example, -48 VDC Input feed or -48 VDC Return). If they are not labeled, and
you are not sure of the source, ask for assistance from a qualified electrician.

Warning: Ensure that the DC power source is off or disconnected on the
remote end before you perform any of the steps in this section. You may
need to switch a circuit breaker off or turn off power at the DC input
source.
Note: Figure 36 shows an example of a site DC input conduit. Your DC
input conduit can look different or can be in a different location than the
one shown in the following examples.
