3.2 Mounting reactors and filters
Mounting system components in a space-saving fashion for the inverters
Many system components for the inverters are designed as sub-chassis components, that is,
the component is mounted on the baseplate and the inverter mounted above it to save
space. Up to two base components can be mounted above one another.
PM240
Basic layout of a PM240 Power Module with line
reactor as base component
The line-side reactors are equipped with terminals while the reactors on the Power Module side are
equipped with a prefabricated 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.
For frame size FSA, in addition to the line reactor, a class A line filter can be used. In this case, the
mains connection is at the bottom.
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).
PM240: frame size FSA with line reactor and
output reactor
In installations containing more than two base-type system components (e.g. line filter + line reactor +
output reactor), the components must be installed to the side of the Power Modules. whereby the line
reactor and line filter are installed under the Power Module and the output reactor to the side.
