Line-side power components
2.3 Line filters for Smart Line Modules and Active Line Modules
NOTICE
Do not interchange the I/Os
The connections must not be interchanged:
• Incoming line cable to LINE/NETZ L1, L2, L3
• Outgoing cable to the reactor or to the Active Interface Module at LOAD L1', L2', L3'
Non-observance may damage the line filter.
High leakage current
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
High-voltage test
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 connection clip for the noise
suppression capacitor must also be removed in the Smart Line Module or in the Active
Interface Module.
NOTICE
Use only approved line filters
Using line filters not approved by SIEMENS for SINAMICS can lead to line-side harmonics
that can interfere with or damage other loads powered from the network.
