15.3.1
Maximum output power rating is 1200 watts for all AC and DC input, three-unit racks.
This means that three modules can operated in a 2+1 redundant configuration to produce
1200 watts output not in non-redundant configuration for more than 1200 watts.
15.3.2
All outputs from the three PowerCassette modules are connected in parallel in the rack
except the +5V 1A Standby outputs which must be externally paralleled by connecting
P2 pins, 2, 7 and 11 together.
15.3.3
The rack depth is 15.06 inches (384mm). The clear plastic rear cover (Option C) adds
2.09 inches (53.1 mm) to the depth for a total of 17.15 inches (436mm).
15.3.4
The V1 and V2 Returns and V3, V4 and V5 Commons are all connected together in
the rack. It is recommended, however, that the Returns and Commons be separately
connected to their respective loads.
15.3.5
Module A is on the left and module C is on the right as seen from front.
