Figure 9 Power terminal block
shows an example of the BIP power terminal block cabling
including ground connections for two 8010co chassis and installed power
supplies.
As shown in this example, both upper and lower chassis are each fully configured
with three power supplies (one is redundant) and require four 60 A direct current
input feeds to the BIP (two feeds are redundant).
For more information, see
“Connecting DC input power feeds to the BIP” on
Caution: All DC input feeds to the breaker interface panel must be
equipped with an overcurrent protection device that limits current to a
maximum of 60 A. The overcurrent protection device can be any
approved, standard-delay, 60 A fuse or circuit breaker with an
interrupting current rating of not less than 10,000 A.
