This procedure explains the arrangement options available for
power system components.
Parts None.
Tools None
This instruction covers installation of the power system into
standard ABB cabinets. Nonstandard cabinets require rack
mount rails positioned at the front of the cabinet to provide
secure mounting points for the power chassis, PEP, and filler
plates. Nonstandard cabinets and rack mount rails must com-
ply with Racks, Panels, and Associated Equipment Racks, Panels, and Associated Equipment, EIA

RS-310-B. Figure
arrangement of each individual component, and Figure
shows the location of the mounting rails.
This procedure describes the physical arrangement in which to
install the power system components. The arrangement is
slightly different for one or two power chassis systems. It is for
reference only and does not contain any installation or
replacement procedures.
Figure PR1-1 shows the two standard mounting schemes. The
front mounting brackets accommodate two power chassis.
When two power chassis are mounted in the same cabinet,
mount the I/O field power chassis in the upper position and
the module power chassis in the lower position. When only one
power chassis is used, mount it in the lower position. Each
power chassis requires its own set of rear mounting brackets.
When using one power chassis, three filler plates are required
to direct cabinet air flow for cooling. When using two power
chassis, two filler plates are required to direct cabinet air flow
for cooling.
