Line Connection Booksize
2.4 Basic Line Filter for Active Line Modules with line reactor
Booksize power units
42 Manual, (GH2), 06/2008, 6SL3097-2AC00-0BP6
2.4.2 Safety information
WARNING
The 100 mm clearances for circulating air above and below the filter must be observed.
This prevents thermal overloading of the filter.
WARNING
The input and output connections/terminals must not be interchanged:
Incoming line 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.
CAUTION
The Line Module 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.
DANGER
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.
Furthermore, the following measures must be taken according to EN 61800-5-1:
Either protective ground conductor cross-sections ≥ 10 mm
2
Cu or installation of a second
protective ground conductor of the same cross-section as the first one.
DANGER
Risk of electric shock. Dangerous voltages are still present for up to 5 minutes after the
power supply has been switched off.
Note
If a high-voltage test is conducted with alternating voltage in the system, the line filters must
be disconnected in order to obtain accurate measurements.
CAUTION
Only the line filters described in this Manual must be used. Other line filters can cause line
harmonics that can interfere with or damage other loads powered from the line supply.
