Configuration
Active Line Modules are always operated together with an Active Interface Module, which
contains the associated Clean Power Filter and pre-charging circuit. The included line filter
enables compliance with the EMC requirements for the "second environment".
Note
The configuration examples of the individual Active Line Modules are used to illustrate the
positioning of the factory-fitted components. They show the maximum possible configuration
of the modules, which contain all options that can be ordered.
Refer to the layout diagrams (AO) on the customer DVD for the precise order-specific
location of the components.
