♦
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 rectifier unit or that are located in the close proximity
of the rectifier unit must be connected to overvoltage limiters (e.g.
RC circuits, varistors).
You will find further information in the brochure "Installation Instructions
for EMC-correct Installation of Drives" (Order No.: 6SE7087-6CX87-
8CE0).
