Line-side power components
2.6 Line filters
Risk of electric shock
A hazardous voltage is still present for up to 5 minutes after the power supply has been
switched off.
Cooling clearances
The 100 mm clearances for circulating air above and below the filter must be observed.
This prevents thermal overloading of the filter.
The input and output connections/terminals must not be interchanged:
• incoming line supply cable to LINE L1, L2, L3
• outgoing cable to line reactor at LOAD L1´, L2´, L3´
The line filter may be damaged if this is not observed.
The S120 Combi must only be connected to the SINAMICS line filter via the associated line
reactor. Additional loads must be connected upstream of the SINAMICS line filter (if
required, via a separate line filter). If this is not observed, other loads could be damaged or
destroyed.
CAUTION
According to product standard IEC 61800-3, RFI suppression commensurate with the
relevant rated conditions must be provided and is a legal requirement in the EU (EMC
Directive). Line filters and line reactors are required to achieve this.
Only line filters listed in this Manual should be used. The use of filters of other makes can
lead to limit value violations, resonances, overvoltages and irreparable damage to motors
or other equipment. The machine manufacturer must provide verification that the machine
equipped with the drive products and the installed suppression elements, e.g. line filters,
are CE/EMC-compliant before the machines are placed in the market.
Note
If a high-voltage test is conducted with alternating voltage in the system, the existing line
filters must be disconnected in order to obtain accurate measurements.
