Connecting DC input power feeds to the BIP
Nortel does not supply the cables for connecting the breaker interface panel to the
DC input power source. You must select cables that comply with the electrical
code of the country where you intend to use the DC-DC power supply.
You can connect up to two “A” feeds and two “B” feeds to your 8010co chassis
configuration for redundancy. Each chassis can require up to 60 A service for
maximum operating power.
As shown in
, the primary B feed (B
1
) provides redundancy
for the primary A feed (A
1
), and the secondary B feed (B
2
) provides redundancy
for the secondary A feed (A
2
).
Danger: Due to high-energy hazards, only qualified service personnel
are permitted to connect the BIP to the DC power source.
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.
Caution: As the installer, you have the sole responsibility for ensuring
that the connection cable used with the breaker interface panel is
appropriate for use with the DC power source to which the power supply
is connected. Consider gauge, flammability, and mechanical
serviceability when determining which cables to use.
Note: An optional third power supply in the chassis provides redundancy
and high-availability operation. In the same way, the BIP provides
redundancy and high-availability operation by allowing two additional
“B” feeds to provide redundancy for single or dual chassis installations.
