2.2 Line filters for Basic Line Modules
2.2.1

Description

In conjunction with line reactors and a systematic plant configuration, line filters limit the
conducted interference emitted by the power modules at the installation location to
permissible values for industry.
2.2.2

Safety information

Line filters are only suitable for direct connection to TN systems.
The cooling clearances of 100 mm above and below the components must be observed.
This prevents thermal overloading of the filter.
CAUTION
The connections must not be interchanged:
• Incoming line cable to LINE/NETZ L1, L2, L3
• Outgoing cable to the reactor to LOAD/LAST L1', L2', L3'
Non-observance may damage the line filter.
CAUTION
The line filters listed conduct a high leakage current via the PE conductor. A permanent PE
connection for the line filter or control cabinet is required due to the high leakage current of
the line filters.
According to EN 61800-5-1, Section 6.3.6.7, the minimum cross-section of the protective
ground conductor must conform to the local safety regulations for protective ground
conductors for equipment with a high leakage current.
Note
If a high-voltage test is conducted with alternating voltage, the line filter must be
disconnected to obtain an accurate measurement result.
If a high-voltage test is carried out with direct voltage, the noise suppression capacitor must
also be disconnected (for the Basic Line Module).
