Rectifier Bafflehloirnting Kit (Nl7D1201)
The Rectifier Baffle/Mounting Kit consists of a set of support brackets for
mounting the NT6D52AA Rectifier to to NT7D12AA Rack, together with a
heat baffle plate. The baffle directs exhaust air from the lower rectifier away
from the inlet to the upper rectifier, thereby allowing cooling by natural
convection.
Configuration guidelines
System options 21/51/61 (DC versions). One per
NT6D52AA Rectifier.
Battery Distribution Box (QBLlS)
Allows the parallel connection of up to three NT6D52AA rectifiers, for
connection to the SL-1 System and to reserve batteries. Includes main fuses,
diode blocking, test points, QPC188 battery monitor card, and sense lead
fusing on connections from each rectifier.
Configuration guidelines
System options 21/51/61 (DC versions). One per
every three NT6D52AA Rectifiers, up to a maximum of two Battery
Distribution Boxes per system.
Battery Distribution Box (QBLl2)
Connects customer-provided power equipment and batteries to the SL-1
System. Allows connection of up to 24 modules.

supplemental cabinets can be added, with up to four rectifiers in the
fist
supplemental cabinet and up to two rectifiers in the second cabinet, for a total
of 10 rectifiers and a total system capacity of 500A. (This power system is
also referred to as the J2412 power
plant
QCA13 is actually the cabinet
designation, but is the more commonly used name.)
