-
The user is responsible for the compliance of his application with the EC directives.
- If you observe the following measure you can be sure that the drive system will not cause any
EMC problems, i.e. comply with the EMC Directive when running the machine.
- 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.
-
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.
- Varnished boards should not be used for installation in accordance with 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.
-
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.
