Basic Line Filters for Active Line Modules

3.7.3.1

Description

Basic Line Filters for Active Line Modules are designed to attenuate conducted interference
emissions in accordance with the specifications contained in the relevant EMC directive.
They are mainly effective in the frequency range from 150 kHz to 30 MHz; this is the range
relevant to ensure compliance with the appropriate standard.
Basic Line Filters can be used in conjunction with a line reactor for 16 kW, 36 kW, and
55 kW Active Line Modules or with an Active Interface Module for 16 kW, 36 kW, 55 kW,
80 kW, and 120 kW Active Line Modules. Data regarding the radio interference voltage

Note
Use of unshielded cables for short distances
Shielded cables should always be routed from the line filter via the Active Interface Module
to the Active Line Module. Because the bending radiuses cannot be maintained for short
distances, unshielded cables can also be used for cable lengths less than 1 m.
The Basic Line Filters can be used in accordance with the following general conditions for
ensuring CE conformity with regard to cable-borne interference:
● The machine/system must only be used in industrial line supplies
● Only connect the Basic Line Filters to TN systems; otherwise an isolating transformer will
be required
● Number of axes ≤ 12 when using a Basic Line Filter with an Active Line Module and a line
reactor
