7.8
In order to achieve an EMC-compatible and interference-free operation within the frame-
work of legislation, the following aspects must be considered.
Please do not hesitate to contact our sales department or the application department of
Baumüller Nürnberg GmbH, if there are any questions.
m
Only use Baumüller motor cables and Baumüller components.
m
Use suitable mains filters recommended by Baumüller Nürnberg GmbH.
m
Mount all components on a single mounting plate with a continuously good electrically-
conductive surface (e.g. galvanized steel plate).
m
Keep the ground connection device/ground plate as short as possible (< 30 cm), using
fine-stranded cables with a large cross section
(refer to
PE connections BM3200, BM3300 rear panel
m
Ensure the correct sequence at installation:
Power supply - fuse - filter -
BM3200, BM3300
- (motor filter) - motor.
m
Ensure that the motor cable is continuous, without interruption.
Do not interrupt motor cables with terminals, contactors or fuses, for example.
m
If possible route the cables on the surface of the grounded mounting plate
(i. e. the least effective antenna height).
m
When routing in parallel, minimum clearance of 20 cm should be observed between
signal and control cables vis-à-vis the power cables.
m
Cables of different EMC categories (e.g. signal cables - mains cables and/or motor ca-
bles) should be crossed at a 90 ° angle.
m
Contact the major cable shield when laying cables through walls, which separate dif-
ferent EMC areas.
m
Contact all the cable’s shields on both sides surface-to-surface and also well-conduc-
tive with ground.

Shielding plan
The shielding of the motor cable as well as of the motor temperature cable must be con-
nected electrically with the mounting plate or with shield sheet (see
HINWEIS!
A ferrite core (part No. 308293) must be used with a DC link connection longer than
3 m to ensure a reliable EMC interference immunity of the
BM3200, BM3300.
The
DC link cables connected with 1C1 and 1D1 must be led through the ferrite core with
3 turns per cable. The ferrite core should be close to the connection X205 of the
BM3200, BM3300.
NOTE!
Baumüller Nürnberg GmbH recommends the shielding connection with shield sheet.
