8.6 Installation in a CE- typical drive system
General
information
•
The responsibility for the compliancy of the EG directives with the
Machine application is one for the user.
– If you observe the following measures, you can assume, that at the operation of the
machine no by the filter module caused EMC-problems occur and that the EG-
directives respectively the EMC-directives are complied.
– If devices are operated in proximity to the filter modules, which do not comply with
the CE-standards in terms of the interference immunity of the EN 500082-2, these
devices can be affected electromagnetic by the filter module.
Design
•
Connect filter modules extensive to the earthed mounting plate:
– Mounting plates with electrical conducting surface (zinc coated or stainless steel) al-
low a durable contacting.
– Coated plates are not adequate for a EMC-conform installation
•
If you use several mounting plates:
– Connect mounting plates extensive and conducting to each other (for example with
copper band)
•
At the installing of lines observe the spatial separation of the power lines from the
control lines.
•
Conduits preferably close by reference potential. Levitating lines operate as anten-
na.
Shielding
•
Metallic cable connections ensure an extensive connection
of the shield with the enclosure
•
At contactors and clamps in the shielded lines:
- Interconnect the shields of the three connected lines and also connect extensive
with the mounting plate
•
At power lines among the interference filter and the drive system longer as 300mm:
- Shield power lines
- Connect the shield of the power lines direct to the drive controller / to the feed
back unit, to the interference filter and to the filter module and connect extensive
to the mounting plate.
•
Shield the control lines:
- Connect the shield beeline to the shield connections.
Grounding
•
Ground all metallic electrically conductive Components (feedback unit, drive control-
ler, interference filter and filter module) by corresponding lines from a central
(ground point, PE-bar).
•
Observe the in den safety regulations defined minimum cable cross section:
- But for the EMC is not the cable cross section decisive, but the surface of the line
and the 2-dimensional contacting.
