Installation in Conformance with EMC Regulations

♦ Use cables with braided shields. Cables with foil shields have a
shielding effect which is worse by a factor of five.
♦ 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).
