Function of the BIP backplane power input connections

241-1501-200 5.2S2
The power input connections located on the BIP backplane are shown in the
figure "Rear of the BIP" (page 53).
The power output connections located on the BIP backplane are shown in the
figures
• "Location of power output cable connectors at rear of two shelves"
(page 82)
• "Backplane connections at the BIP" (page 81)
The BIP backplane power connections are the terminations for input power
feeds up to 100 A, and for output power cables from the BIP to the shelves
and cooling units. A four-BIM model BIP supports four input feeds (a battery
and battery return wire per BIM), while a two-BIM model supports two power
feeds (four cables). A backplane safety cover overlays the backplane to
prevent inadvertent shorts from metallic contact with the connectors. Each
power input connection is covered by an insulating boot.
Each Passport 15000 or 20000 in the same NEBS 2000 frame requires four
power cables (two feeds) through the same BIP.
Installing top power cabling involves routing four or eight cables (two or four
feeds) from the dc power source along an overhead trough (or equivalent
setup) and down to the BIP.
Installing bottom power cabling involves routing four or eight cables (two or
four feeds) from the site dc power source under or through the floor and up to
the BIP.
Installing the feeds through conduit or not depends on the access
classification of your site as restricted or non-restricted. For information on
classifications, see 241-1501-205 Passport 15000, 20000 Site Requirements
and Preparation Guide.
The table "BIP backplane power connections in a dual shelf frame" (page 75)
shows how the power connections on the backplane of the BIP are connected
to other parts in the Passport 15000 frame setup.
