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

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

? = Suitable as base-type
O = Not suitable as base-type
– = Not available (use Power Modules with integrated line filter)

Basic layout of a PM340 Power Module with line reactor as base component

The line-side reactors are equipped with terminals and the reactors at the Power Module end with a pre-assembled cable. 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.

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 figure above. In this case, the line connection is below.

Power Modules of frame size FSB and higher are available with integrated line filters, alleviating the need for an external line filter.

For configurations 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.
