15.2 Two-Unit Rack.
The two-unit, 19-inch rack is shown in Figure 10 with connections and
pin designations. There is a choice of single or dual IEC60320 AC input connectors or
single or dual terminal block AC or DC input connectors. The various connector versions
are summarized in the following table.

15.2.1
Maximum output power rating is 1200 watts for all models except Model Suffixes C
and D (for input connector designation). For these two models the maximum output
power is 600 watts for 100- 120VAC input or 1000 watts for 200-240VAC input. Thus
for 100-120 VAC input the two PowerCassette models can be employed in a 1+1
redundant configuration or for 200-240VAC they can be employed in a non-redundant
configuration but only up to 1000 watts output power. There are no limitations for DC
input models all of which can produce up to 1200 watts output with 36-72VDC input.
15.2.2
All outputs from the two PowerCassette modules are connected in parallel in the
rack except the +5V 250 mA Standby outputs which must be externally paralleled by
connecting P2 pins 3 and 11 together.
15.2.3
The rack depth is 14.00 inches (356mm). The clear plastic rear cover (Option C) adds
2.09 inches (53.1mm) to the depth for a total of 16.09 inches (409mm).
15.2.4
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.
15.2.5
The front view arbitarily shows dual IEC60320 connectors; the back view shows dual
terminal block connectors.
15.2.6
Module A is on the left; module B is on the right (as seen from the front).
15.2.7
For dual input racks, each input goes separately to the PowerCassette on the same side
of the rack.
