4.4 Installation of a CE-typical drive system
4.4.1 General notes
( The electromagnetic compatibility of a machine depends on the type of
installation and care taken. Please observe:
- Assembly
- Filters
- Screening
- Grounding
( For diverging installations, the conformity to the CE EMC Directive requires
a check of the machine or system regarding the EMC limit values. E.g. with:
- the use of unscreened cables
- the use of group RFI filters instead of the assigned RFI filters
- Operation without mains choke
- Multi-motor drive systems
The user of the machine is responsible for compliance with the EMC
Directive.
If you observe the following measures, you can assume that the machine will
operate without any EMC problems caused by the drive system, and that
compliance with the EMC Directive and the EMC law is achieved.
If devices which do not comply with the CE requirement concerning noise
immunity EN 50082-2 are operated close to the controller, these devices may be
interfered electromagnetically by the controllers.
Because of the earth-potential reference of the RFI filters, the CE-typical drive
systems which are described are not suitable for the connection to IT-mains (mains
without earth-reference potential).
For the use of 48XX/49XX drive systems in residential areas observe the following:
( Check that the radio interference suppression level at the supply to the site
of operation complies with the standard (EN55022 class B).
( Check that the permissible level for radio interference (EN55022 class B) is
not exceeded around the site of operation.
