EMC Measures for Design and Installation
Connecting
the
Mains
Choke
Keep connection lines of the mains choke at the drive controller as short
as
possible and twist them.
Installing
the
Motor
Power
Cable
• Use shielded motor power cables or run motor power cables
in
a shielded
duct
6.2
6.2.1
6.2.2
• Use the shortest possible motor power cables
• Ground shield of motor power cable at both ends over the largest possible
surface area to establish a good electrical connection
• Run motor lines
in
shielded form inside the control cabinet
• Do not use any steel-shielded lines
• The shield
of
the motor power cable mustn't
be
interrupted by mounted
components, such as output chokes, sine filters or motor filters
EMC-Optimallnstallation
in
Facility
and
Control
Cabinet
General
Information
For EMC-optimal installation, a spatial separation of the interference-free area
(mains connection) and the interference-susceptible area (drive components)
is
recommended,
as
shown
in
the figures below.
[@f' For EMC-optimal installation
in
the control cabinet, use a separate
control cabinet panel for the drive components.
Division
Into
Areas
(Zones)
Exemplary arrangements
in
the control cabinet: See section Control Cabinet
Moun
ti
ng
According to
In
terference Areas - Exemplary Arrangements,
page
52.
We distinguish three areas:
1. Interference-free area of contr
ol
cabinet
(area
A)
:
This includes:
• Supply feeder, input terminals, fuse, main switch, mains side of
mains filter for drives and corresponding connecting lines
• Control voltage or auxiliary voltage connection with power supply
unit,
fuse
and
ot
her
parts
unless
connection
is run via
the
mains
filter
of the AC drives
• All components that are not electrically connected with the drive sys-
tem
2. Interference-susceptible area
(area
B)
:
• Mains connections between drive system and mains
fi
lter for drives,
mains contactor
• Interface lines
of
drive controller
3.
Strongly interference-susceptible area
(area
C):
• Motor power cables including single cores
Never run lines of one of these areas
in
parallel wi
th
lines of another area so
that there isn't any unwanted interference injection from one area to the other
and that the filter
is
jumper
ed
with regard to hi
gh
frequency. Use the shortest
possible connecting lines.
Recommendation
fo
r complex systems: Install drive components
in
one cabinet
and the control
un
its
in
a second, separate cabinet.
