♦ Use a noise suppression filter in the incoming powerline.
Connect the noise suppression filter to ground and to the converter
through a large surface area.
It is best to directly mount the noise suppression filter on the same
good conductive mounting surface as the converter or inverter.
You must insert a line reactor between the noise suppression filter
and the unit.
♦ Contactor operating coils that are connected to the same supply
network as the converter or that are located in close proximity of the
converter must be connected to overvoltage limiters (e.g. RC
circuits, varistors).
Further information is contained in the chapter 3 "Instructions for
Design of Drives in Conformance with EMC Regulations" of the
Compendium. The Compendium can be found on the attached CD and
can also be ordered as a hard copy (Order No.: 6SE7087-6QX60).
This product has limited availability in accordance with IEC 61800-3.
This product can cause radio interference in residential areas. In such a
case, it may be necessary for the operator to take suitable action.
In line with the EMC product standard for variable-speed drives
EN 61800-3:1996 + A11:2000 Chapter 6.3.2.3 b) drive systems (PDS =
Power Drive Systems) have to comply with the limit values (in
accordance with Table 11 and Table 12 of the above-mentioned
standard).
For technical reasons there are a number of applications in which it is
not possible for PDS to comply with these limit values.
Such applications are:
♦ IT networks in complex systems
♦ Applications in which the necessary dynamic operational behavior is
limited on account of filter effects.
This note must be particularly observed for option L20 (operation on
non-grounded networks).
