Integration (continued)
Many system components for PM240 Power Modules are de-
signed as base components, that is, the component is mounted
on the baseplate and the PM240 Power Module above it in a
space-saving construction. Up to two base components can be
mounted above one another.
The following diagram shows the basic layout of a PM240 Power
Module with line reactor as base component. The line-side reac-
tors are equipped with terminals and the reactors at the Power
Module end with a pre-assembled cable. In the final installation
position, the mains terminals are at the top on frame sizes FSA
to FSC, and at the bottom on frame sizes FSD to FSE.

If a class A line filter is installed in addition to the line reactor on
frame size FSA, the components must be arranged as shown in
the diagram below. In this case, the line supply connection is be-
low.
Power Modules of frame size FSB and higher are available with
integrated class A line filters; an external class A line filter is not
required in this case.

For configurations involving more than two base-type system
components, e.g. line filter + line reactor + output reactor, indi-
vidual components must be mounted to the side of the Power
Modules. In this instance, the line reactor and line filter must be
installed under the Power Module and the output reactor to the
side.
