HINWEIS!
The important information on EMC-compliant installation can be found in these in-
struction handbook. Additional notes on building a CE-compliant system, that are im-
perative to take heed of, can be found in the Baumüller manual „Mains filter BFN“.
This manual can be obtained from Baumüller Nürnberg GmbH.

m
Use Baumüller motor cables and Baumüller components.
m
Use a suitable mains filter of Baumüller Nürnberg GmbH
m
Mount all components to one single mounting board with well electroconductive surface (e.
g. galvanized steel plate).
m
Establish the ground connection converter/ground plane as short as possible (< 30 cm) with
fine-wired cables and a great cross section (> 10 mm
2
).
m
Assure, that the motor cables always consist of one piece.
Do not interrupt the motor cables e. g. by terminals, conductors, fuses a.s.o.
m
Run the cables directly on the surface of the grounded mounting board.
(smallest possible effective aerial height).
m
Keep a minimum clearance of 30 cm between signal/control and 24V-wires towards electric
power cables at parallel laying.
m
Cross cables with different EMC categories (signal cables - supply cables or motor cables)
only in a 90° angle.
m
Contact the external cable screens when passing through walls, which separate different
EMC ranges.
m
Connect the cable shields of the Mono Power Unit / Power Module-devices plane on both
ends and highly conductive with ground.
m
It is recommended to use protection elements against overvoltage in each 24 V control cab-
inet sub-distribution (e.g. Phoenix Contact part no. 2839318 type: PT2-PE/S-24AC-ST) when
using a peripheral 24 V supply (that means the 24 V power supply is not within the device’s
control cabinet).
NOTE
The capacitive coupling of the signals is reduced by factor 5 if a clearance of at least
30 cm is maintained compared with a cable laying directly side by side.
Baumüller has already considered on EMC view that the recommended clearance of
30 cm is not maintained on the supply and the Baumüller devices, therefore this is
uncritical and permitted.
