Description

Active Interface Modules are line-side interfaces for the Active Line Modules.
They contain the following functional units:
● Line reactors
● Low-frequency/switching frequency filters
● Line filter EN 61800-3 Category C3 up to 350 m total motor cable length
● Reduction of the stress on the motor insulation from system-dependent resonance factors
Data regarding the radio interference voltage categories and maximum total cable lengths
that can be achieved
and line filters (Page 135).
The Active Interface Module is fitted with a fan. The 24 V supply is essential for operating the
component. Connection of the temperature signaling contact to the Active Line Module is
also required.
Maximum total cable length = Σ motor cables, line feeder cable from line filter to the Line
