7.8
In order to have EMC-compliant and problem-free use within the framework of the legis-
lation, the following aspects must be taken into account.
In case of any questions, please contact Sales or the Applications department of
Baumüller
Nürnberg GmbH.
m Use Baumüller components.
m Use a suitable mains filter
m Mount all components to a single mounting board with well electroconductive surface
(e. g. galvanized steel plate).
m Carry out the earth connection converter/earth plate as short as possible (< 30 cm) with
fine-wired cables and a big cross section (> 10 mm
2
).
m When installing, attend to the correct order:
mains - fuse - filter - choke - BM4100 (NWR).
m Run the cables directly on the surface of the earthed mounting board.
(smallest possible effective aerial height).
m Keep a minimum clearance of 20 cm between signal and control wires towards electric
power cables at parallel laying.
m Cross cables with different EMC categories (signal cables - mains cables) only in a 90°
angle.
m Contact external cable screens when executing through-hole mounting, which sepa-
rate the different EMC ranges.
m Connect the shield of the cables of the b maXX-devices plane on both ends and highly
conductive with earth.
7.8 Mains filter and surge-protection module
The use of the mains filters mentioned in the manual is mandatory. The requested filters
are UL-listed, see
ZMains filters– on page 118.
When using a mains filter an surge-protection module is necessary, refer to ZSurge pro-
tection module– on page 118.
7.9 Main contactor and charge contactor
In order to control the pre-charge and the main operation a main contactor as well as a
charge contactor must be used as a component of the mains inverter in the control cabi
-
net. The data of the main contactor and of the charge contactor is to be found in ZMain
contactor and charge contactor– on page 124.
7.10 HF mains choke
Because of the working principle of the mains inverter an HF mains choke is necessary.
Data of HF mains chokes are to be found in
ZPower chokes– from page 123.
NOTE!
The assembly of mains inverter - choke - filter must be built up more compact in order
to reduce EMC interferences.
