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
mounted vertically
on
the mounting plate from modules and lines
in
area A or
use shielded lines.
Only
connect power supply units for auxiliary or control voltage connections
in
the drive system to the mains via a mains filter. See 6.2.2 Division Into Areas
(Zones), page
50
.
Install
the shortest possible lines between drive controller and filter.

Only
in
exceptional cases should you connect power supply unit and fusing for
6.2.6
Connection
the control voltage connection to phase and neutral conductor.
In
this case,
mount and install these components
in
area A far away from the areas B and
C
of
the drive system. For details see section 6.2.4 Design and Installation
in
Area
A-
Interference-Free Area of Control Cabinet, page 53.
Run the connection between control voltage connection of the drive system 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
interference
fields to area A (transmitting antenna effect).
Design
and
Installation
in
Area
C-
Strongly
Interference-Susceptible
Area
of
Control
Cabinet
Area C mainly concerns the motor power cables, especially at the connection
point at the drive
controller.
Influence
of
the
Motor
Power
Cable
The longer the motor power cable, the greater its leakage capacitance. To
comply with a certain EMC limit value, the allowed leakage capacitance
of
the
mains
filter
is
limited. For the calculation
of
the leakage capacitance, see the
documentation
on
the drive system of the drive controller used.
~
• Run the shortest possible motor power cables.
• Only
use
shielded
motor power cables by Rexroth.
Routing
the
Motor

Cables

Cables
surfaces, both inside the control cabinet and outside of it,
in
order to minimize
radiation of interference fields. If possible, route the motor power cables and
motor encoder cables
in
metal-grounded cable ducts.
Routing
the
Motor
Power
Cables
and
Mains
Connection
Lines
Route the motor power cables and motor encoder cables
• with a distance
of
at least d5 =
100
mm
to interference-free lines, as well
as to signal cables and signal lines
(alternatively separated by a grounded distance plate)
•
in
separate cable ducts, if possible
For converters (drive controllers with individual mains connection), route motor
power cables and (unfiltered) mains connection lines
in
parallel
for
a
maximum
distance
of
300
mm.
After that distance, route motor power cables and power
supply cables
in
opposite directions and preferably
in
separate
cable
ducts.
Ideally, the outlet
of
the motor power cables at the control cabinet should
be
provided in a distan
ce
of at least
d3
= 200
mm
from the (f
il
tered) power supply
cable.
