Integration
PM340 Power Modules in blocksize format communicate via the
PM-IF interface with the CU310-2 Control Unit or the CUA31
Control Unit Adapter.

Many system components are designed as base components
for PM340 Power Modules, i.e. the component is mounted on the
baseplate and the PM340 Power Module in front in a space-sav-
ing construction. Up to two base components can be mounted
in front of one another.

Basic layout of a PM340 Power Module with
line reactor as base component
The side reactors are equipped with terminals on the line side
and with a pre-assembled cable on the Power Module side.
When installed, the mains terminals are at the top on frame sizes
FSA to FSC, and at the bottom on frame sizes FSD and FSE.
PM340 Power Module in frame size FSA with line reactor and line filter
If 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 above. In this case, the line supply connection is at the
bottom.
Power Modules of frame size FSB and higher are available with
integrated line filters, alleviating the need for an external line
filter.
For arrangements involving more than two base-type system
components, individual components must be mounted to the
side of the Power Module. In this instance, the line reactor must
be installed behind the Power Module and the braking resistor to
the side.
