Power and DC link components which are optionally
available 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
Availability as base components
Many system components for PM250 Power Modules are de-
signed as base components, i.e. the component is mounted on
the baseplate and the PM250 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 PM250 Power
Module with additional line filter class B as base component.

nents:

1)
A line reactor is not required and must not be used in conjunction with a
Power Module of type PM250.
2)
A PM250 Power Module is capable of line-commutated energy feedback.
A braking resistor cannot be connected to this module and and is not nec-
essary.
