10.1 Installation and connection regulations
!
Warning
The filters become extremely hot in the vicinity of the internal line supply
resistors. If other components are mounted above a filter module (clearance <
400 mm) then a heat barrier can be mounted which deflects the heat away from
these components. The mounting position must guarantee that the cooling air
flows vertically through the filter.
!
Caution
Ensure that the line filter is correctly connected to the line supply in accordance
with the regulations:
LINE L1, L2, L3 for line filters for the UI module and I/R module for sinusoidal
current operation.
If this is not observed, the line filter could be damaged. Also refer to the con-
nection diagrams 10-1.
Caution
The listed line filters conduct a high leakage current through the protective con-
ductor. A permanent PE connection of the line filter and the cabinet is required
as a result of the high leakage current of the filter.
Measures in accordance with EN 50178/94 Part 5.3.2.1 must be applied, e.g.
protective conductor ( 10 mm
2
Cu) or a second conductor must be routed in
parallel to the protective conductor through separate terminals. This conductor
must fulfill the requirements for protective conductors according to IEC
364–5–543 itself.
The ”EMC Guidelines for SINUMERIK and SIROTEC controls” (Order No.:
6FC5297–0AD30–0AP1) should be observed, refer to the documentation over-
view on the first cover page.
