Signs and labels
2.11 Signs and labels
The following symbols and information signs are located in the working area. They refer
to the immediate vicinity in which they are affixed.
WARNING!
Risk of injury due to illegible symbols!
Over the course of time, stickers and symbols on the device can become dirty or otherwise unrecognizable.
Therefore:
m Maintain all safety, warning and operating labels on the device in easily readable
condition.
Electrical voltage
Only qualified personnel may work in the marked workspace.
Unauthorized persons may not touch the marked working materials.
DANGER!
Risk of injury due to hot surface!
The surfaces of the device can heat up to temperatures of > 70°C!
Therefore:
There is a differential structure of current supply systems and it is distinguished between
three basic types, referring to their grounding, which is accordant to DIN VDE0100 part
300 and accordingly to IEC 60364:
m In a TN-system one point is directly grounded
trical installation is connected via protective
tors with this point.
m In a TT-system a point is directly grounded (
installation is connected to ground connections, which, however, are separated from
the signal ground.
m In an IT-system there is no direct connection between activ
N) and grounded parts (PE). The cabinets of the electrical installation are grounded.
The separation is reached, by the use of an isolating transformer or with the use of an
independent current source (generator, battery).
If there is an adequate low-impedance grounding within the TN- or the TT-system, then
a line-side fuse is activated. A high-impedance grounding does not activate the fuse, so
that the ground currents (error current) can be potentially dangerous. For this reason, circuit breakers are used for the error current monitoring.
At a short-circuit to ground, no ground current can flow and the line-side fuses cannot be
activated, by which the operation can be kept up. Only a second short-circuit to ground at
another phase would cause an current error, which can trigger a fuse. In order to detect
the first short-circuit to ground an insulation monitor and for the second short-circuit to
ground, a current error monitoring, are necessary.

In order to comply with the limit values of the EMC-standards, the use of Baumüller mains
filters BFN-3-1-XXX-X01 is required.

m Grounded industrial systems of hard or low impedance
they can not be used in
m Grounded industrial systems of insulated and high impedance.
m Grounded wye-supply systems
m Grounded industrial systems of hard- or low impedance
In order to allow the compliance with the limit values for the conducted interferences („external“ second environment - EN 61800-3, table 9) in low-impedance grounded low-voltage systems use Baumüller mains filters combined with Baumüller converters, Baumüller
motor cables and Baumüller motors. If all installation- and EMC-notes of this Handbook
are complied with, it is assumed that the interference-suppressed drive accords to the
protection requirements of the EMC-Directive 89/336/EWG and of the EMC-act (EMVG).

IT-systems
ZSystem types– on
page 15
The use of mains filters in IT-systems is less effective and no EMC limits are defined.
„The use of EMC-filters in an insulated or a grounded industrial distribution system
of high impedance can cause a safety risk. No limit values can be defined at IT-systems,
which are used for complex industrial systems.“ (EN 61800-3, chapter 6.3.2.3, b).
NOTE!
An error case (motor ground connection) can lead to overload and perhaps destruction of the mains filters.
The use of mains filters BFN-3-1-XXX-X02 is possible, but it is not recommended to
apply mains filters in IT-systems. The transient emissions can exceed the limits of
category C3.
Mains filters are combinations of capacitors, chokes, resistors and voltage limiters, which
reduce the electromagnetic influence of environment. The power direction is bidirectional,
i. e. the outgoing cable-guided faults from the converter are reduced, but also the interference resistance of the drive against supply faults, as they appear with lightning strokes,
fuse blow or simple switching operations, is improved at the same time.
The mains filters of the series BFN ... were developed for the BAUMÜLLER-power electronics referring to its attenuation behavior. Its application enables the compliance with
the limitation values which are required for the branch of industry (second environment)
of the EMC product standard for variable-speed electrical power drive systems
EN 61800-3 as well as the „Generic Standards“ EN 61000-6-4.
When using the filter series BFN ... in the combination with Baumüller converters,
Baumüller-motor cables and Baumüller motors and under consideration of the installation- and mounting notes in this Instruction Handbook and in the Instruction Handbook of
the power converter, the protection requirements of the European EMC Directive and of
the EMC Act (EMVG) accordant to §3, sec. 1 are fulfilled.
Description of the devices

NOTE!
The emission of radio interferences is to a high level dependent of the wiring, the volume expansion and the arrangement of the components in the installation. This is
why the ensuring of the EMC according to the legal regulations only is possible with
the completed installation and therefore is in the responsibility range of the manufacturer of the installation or of the operating authority. (EMVG § 6, sec. 9).
NOTE!
Components of the Baumüller Nürnberg GmbH are intended for installation in commercially available control cabinets.
There are several reasons to operate the components and devices in commercial
control cabinets. Particularly the following is ensured:
m The required contact protection is ensured.
m The thermal environmental conditions (temperatures, relative humidity, cleanli-
ness of the coolants, ...), described in the technical data of the components and
the devices, are ensured.
m The mechanical environmental conditions described in the technical data of the
components and the devices (variations, vibrations, ...), are ensured.
m The notes meeting the EMC-configuration and the EMC-structure (shielding con-
cept, laying principles, implementations,...) described in the technical data of the
components and devices can be implemented.

Power supply
Load
4.1.1Functional description
General information
The resulting impedance of the parts used in the filters leads to an optimum mismatch
between the mains- and the load impedance. Now the interference-current can return to
its interference source. The dropping harmonic voltages at the impedance of the system
can be reduced substantially between the frequency range 150 kHz ... 30 MHz .
WARNING!
Filters cause high discharge currents and are incompatible, if they have RCDs. The
notes of EN 50178 must be considered when configuring. Due to the high discharge
currents the cross-section of the ground conductors at the filter must be at least 10
2
(EN 50178, chapter 5.3.2.1). The grounding conductor must be connected to
mm
the filter before commissioning.
NOTE!
In order to return the interference current with low impedance to its interference
source, mounting must be made on a conductive mounting plate (mounting of the
mains filter and of the power converter, which must be cleared and of the bonded
face-to-face contacting of the motor cable screen). The use of unvarnished mounting
plates provides the best results.

The emission of radio interferences is highly dependent of the wiring, the spatial expansion and the assignment of the components in the system. Therefore the electromagnetic compatibility compliant to the regulations can be assured at the assembled
system only. Therefore the system manufacturer or the operator is responsible for assuring EMC (EMVG §6, chapter 9).

7.5.1General information about converters
In converters of the Baumüller Nürnberg GmbH semiconductors are used. These can
minimize power loss by quick switching. Therefore a compact size of the devices is possible. The semiconductor generates electromagnetic waves due to this quick switching.
Special preconditions must be observed to avoid electromagnetic influences by switching
procedures.
The following causes are the reason for interferences in the drive system:
m Capacitive discharge currents. Here is a great rate of rise of voltages when switching
semiconductors.
m Great currents and rate of rise of voltages in the motor cables. The interference energy
which is bounded into magnetic fields reaches frequencies of a few hertz to about
30
MHz. Due to the great rate of rise of voltages additional electromagnetic fields with
frequencies to about 600
m Great cycle rates and quick logic circuits (electromagnetic field with frequencies of
16
MHz to 1 GHz).
m System perturbation and harmonics. Here commutation procedures and non sinusoi-
dal mains loads occur. This particularly occurs at line-commutated converters (100 Hz
to 20
kHz).
EMC is decisively dependent of the assembly of the individual parts and components in
the control cabinet. The system can be configured compliant to the latest EMC-knowledge described in the following. This way the statutory regulations can be complied with.
The following configuration notes must be considered to assure EMC.

system. Herewith effective loop area for the magnetic coupling is reduced.
m A minimum distance of 20 cm should be kept between the conductors at a parallel in-
stallation of signal- and control cables and the power cables.
m The distance between cables with very high interference potential and with cables on
the mains side of the mains filters should be at least 30 cm.
m Try to cross cables with different EMC-categories in a 90°-angle.
m The conductors of each core pair must be twisted at symmetric signal transmission (for
example differential amplifier inputs for the speed value). The core pairs must be twist
ed with the other core pairs.

must be finely stranded. Use great cross-sections (recommended >

parts, which cause interferences (for example contactors, transformers, chokes) and
for susceptible parts (for example Ps, bus systems).

Groundingm In order to reduce the influence of high-frequency interferences, which were generated
when operating the power converter, the basic star-grounding does not comply to
EMC. A reference surface is required to connect the devices large-surfaced with the
potential to ground (for example a metallic bright mounting plate and cabinet parts)
m Mount the power converter with its mains filters and the bonded face-to-face screen
contactor of the motor cable to the same reference surface.
m All grounding conductors and screens should be led directly above ground, so that no
ground loops occur.
m Ground the controller-reference potential of the power converter. Connect with a great
cross-section and a short cable (<
m Remove insulating layers (varnish, adhesive) from the ground connections. Use ser-
rated washers (DIN 6798) to reach the surface. This way a durable conductive contact
is achieved. . In order to prevent corrosion of ground connection, select suitable metal
pairs (observe electrolytic series of metals). Keep the conductive electrolytics from the
connection by using a protective coating (for example grease)
m The screens must be bonded at both ends face-to-face and well conductive to ground.
This way the effects of magnetic or highly-frequent interference fields can be attenuat
ed. The receiver should be connected isolated, the transmitter should be connected
capacitive, if problems with ground loops occur (for example double grounding of set
value cable screening).
m When leading external cable screens through walls, contact the different EMC-ranges
separated from one another.
Cables, which are led through walls of screening cabinets without special precautions
(for example filtering), can influence the screening effect of these cabinets. Therefore,
also connect the cable screenings with well conductivity at the cabinet’s outlet with the
screening wall.

DANGER!
Danger to life due to electrical current!
Energized parts are dangerous to life.
Therefore:
m The device, the mounting range and the parts, which are to be mounted (for exam-
ple supply cables) must be off circuit during complete mounting
m The cross-section of the grounding conductor must be greater than 10 mm
h Install all cables compliant with EMC.
h Connect cables (see ZConnection diagram– on page 55).
(Pay attention to permitted torques!)

NOTE!
Installation notes:
m Don’t connect mains filters in parallel.
m Don’t connect mains filters of the same type in series - the attenuation character-
istics will not be approved.
m Connect the PE-terminal on the load-side of the filter with low impedance to the
mounting board. Ideal is a zinc plated L-bracket or with a HF-earth strap.
m Suppress each drive individually from interferences. In case you have to suppress
all of the drives from interferences together, do not interrupt any of the screens between converter and the mains filter. This means the screened lines are not interrupted by fuses, contactors or others, except with eventual necessary power
chokes.
Inevitably, when operating this electrical device, certain parts of it are energized with
hazardous voltage.
Therefore:
m Pay heed to areas on the device that could be dangerous during the mainte-
nance.
m Pay heed to areas that could still be electrically energized after operation.
WARNING!
Risk of injury due to improperly performed maintenance work!
Improper maintenance can lead to severe personal injury and material damage.
Therefore:
m Before beginning work, make sure that there is enough space for mounting.
m Make sure that the mounting area is kept clean and orderly. Parts and tools that
are loosely stacked or lying around are a potential accident source.
