Active Interface Modules, air-cooled

8.3.1

Booksize format

Active Interface Modules are line-side interfaces for the Active Line Modules.
They contain the following functional units:
● Line reactor
● Low-frequency/switching frequency filters
● Line filters to EN 61800-3, category C3, max. total motor cable length 350 m (shielded)
● Reduction of the stress on the motor insulation from system-dependent resonance factors
In conjunction with an Active Line Module and an EMC-compliant configuration the following
radio interference voltage categories are achieved:
● EN 61800-3 category C3 without an additional line filter up to a total cable length of
350 m (shielded) for 16 kW, 36 kW, 55 kW, 80 kW and 120 kW components
● EN 61800-3 category C2 with an additional Basic Line Filter up to a total cable length of
350 m (shielded) for 16 kW, 36 kW, 55 kW, 80 kW and 120 kW components
● EN 61800-3, category C3, with an additional Basic Line Filter up to a total cable length of
– 630 m (shielded) for 16 kW and 36 kW components
– 1000 m (shielded) for 55 kW, 80 kW and 120 kW components.
