■ Integration
Power and DC link components which are optionally avail-
able depending on the Power Module used
The following line-side power components, DC link components
and load-side power components are optionally available in the
appropriate frames sizes for the Power Modules:
U = Base component
S = Lateral mounting
I = Integrated
– = Not possible
F = Power Modules available with and without integrated class A filter
Available as base components
Many system components for PM250 Power Modules are de-
signed as base components, that is, the component is mounted
on the baseplate and the PM250 Power Module above it in a
space-saving design. Up to two base components can be
mounted above one another.
The following diagram shows the basic layout of a PM250 Power
Module with additional class B line filter as base component:

nents:

1)
A line reactor is not required and must not be used in conjunction with a
PM250 or PM260 Power Module.
2)
Line-commutated energy recovery is possible in conjunction with a PM250
or PM260 Power Module. A braking resistor cannot be connected and is
not necessary.
