4.3 Installation of a CE-typical drive system
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. This is for instance valid for
- the use of unscreened cables,
- the use of group RFI filters instead of assigned RFI filters,
- the operation without mains filter.
- The compliance of the machine application with the EMC Directive is in the responsibility of the user.
- 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 EN50082-2 are operated
close tothe controller, these devices may be disturbed electromagnetically bythe controllers.
Assembly - Connect controller, mains choke, and mains filter to the grounded mounting plate with a wire of large a
cross-section as possible:
- Mounting plates with conductive surfaces (zinc-coated, stainless steel) allow permanent contact.
- Painted plates are not suitable for the installation in accordance with the EMC.
- If you use several mounting plates:
- Connect as much surface as possible of the mounting plates (e.g. with copper bands).
- Ensure the separation of motor cable and signal or mains cable.
- Do not use the same terminal strip for mains input and motor output.
- Cable guides as close as possible to the reference potential. Unguided cables have the same effect as aerials.
Filters - Use mains filters or RFI filters and mains chokes which are assigned to the controller:
- RFI filters reduce impermissible high-frequency interference to a permissible value.
- Mains chokes reduce low-frequency interferences which depend on the motor cable and its length.
- Mains filters combine the functions of mains choke and RFI filter.
