Electromagnetic Compatibility (EMC)
Grounding
In the case of bad ground connections in the installation, the distance between the lines
to the grounding points E1, E2 in area A and the other grounding points of the frequen‐
cy converter should be at least d4=400 mm, in order to minimize interference injection
from ground and ground cables to the power input lines.

Point of Connection for Environment Grounding Conductor at Machine, Installation,
Control Cabinet
The equipment grounding conductor of the power cable of the machine, installation or
control cabinet has to be permanently connected at point PE and have a cross section
of at least 10 mm or to be complemented by a second equipment grounding conductor
2
via separate terminal connectors (according to EN 61800-5-1: 2007, section 4.3.5.4). If
the cross section of the outer conductor is bigger, the cross section of the equipment
grounding conductor must be accordingly bigger.
11.3.5 Design and installation in area B – interference –susceptible
area of control cabinet
Arranging Components and Lines
Modules, components and lines in area B should be placed at a distance of at least
d1=200 mm from modules and lines in area A.
Alternative: Shield modules, components and lines in area B by distance plates moun‐
ted vertically on the mounting plate from modules and lines in area A or use shield
lines.
Only connect power supply units for auxiliary or control voltage connections in the fre‐
quency converter to the mains via a mains filter. See
page 0 .
Install the shortest possible lines between drive controller and filter.
Control Voltage or Auxiliary Voltage Connection
Only in exceptional cases should you connect power supply unit and fusing for the con‐
trol voltage connection to phase and neutral conductor. In this case, mount and install
these components in area A far away from area B and C of the frequency converter.
Run the connection between control voltage connection of the frequency converter and
power supply unit used through area B over the shortest distance.
Line Routing
Run the lines along grounded metal surfaces, in order to minimize radiation of interfer‐
ence fields to area A (transmitting antenna effect).
