4.9 Active Interface Module

4.9 Active Interface Module
4.9.1

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 filters to EN61800-3, category C3, max. total motor cable length 350 m (shielded)
In conjunction with the associated Basic Line Filter and an EMC-compliant design, the
following voltage interference limit values are observed:
● EN 61800-3, category C3, max. total cable length 1000 m
● EN 61800-3, category C2, max. total cable length 350 m
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.

Safety information

CAUTION
Active Interface Modules must only be operated if the option "Line filter available" has been
set for the Active Line Module in the commissioning wizard, and if "AIM 400 V xxkW
(6SL3100-0BE**-*AB*)" has been selected as the line filter. Alternatively the parameter for
line filter adjustment can also be set manually: p0220 = 4*.
If this is not observed, the Active Interface Modules may overheat.
The Active Interface Modules conduct a high leakage current via the PE conductor. A
permanent PE connection for the Active Interface Module or control cabinet is required due
to the high leakage current of the Active Interface Module.
Furthermore, the following measures must be taken according to EN 61800-5-1:
Either protective ground conductor cross-sections ≥ 10 mm
protective ground conductor of the same cross-section as the first one.
A ventilation clearance of 80 mm above and below the components must be observed.
