2EC-Directives / Declaration of conformity
What is the purpose of EC-Directives?
The EC-Directives have been drawn up by the European council to define common techni-
cal standards and certification procedures within the European Community. At the moment
there are 21 EC-Directives for product sectors. The directives are or will be converted in
national laws by the member states. If a certificate is conferred in one member state, it is
valid in all other member states automatically.
The directives only describe the basic standards. The technical details are or will be de-
scribed in harmonized European standards.
What is the meaning of the CE-marking?
After a conformity-assessment-procedure the conformity with the standards of the EC-
Directives is certified by fixing the CE-marking. Within the EC there are no trading obsta-
cles for a CE-marked product.
Power feedback units with CE-marking themselves are compliant with the Low-Voltage
Directive only
.
For observing the EMC Directive recommendations are made.
2.1 EC-Low-Voltage Directive

Safety and application notes
for drive converters
(Low-Voltage Directive (2006/95/EEC)
1.
General
During operation, power feedback unit may have, according to their
type of protection, live, bare, in some cases also movable or rotating
parts as well as hot surfaces.
Non –authorized removal of required cover, inappropriate use, incor-
rect installation or operation, creates the risk of severe injury to per-
sons or damage to material assets.
Further information can be obtained from the documentation.
All operations concerning transport, installation and commissioning as
well as maintenance must be carried out by qualified, skilled person-
nel (IEC 364 and CENELEC HD 384 or DIN VDE 0100 and IEC-
Report 664 or DIN VDE 0110 and national regulations for the preven-
tions of accidents must be observed).
According to this basic safety information qualified skilled personnel
are persons who are familiar with the erection, assembly, commission-
ing and operation of the product and who have the qualifications nec-
essary for their occupation .
2.
Application as directed
Power feedback units are components which are designed for installa-
tion in electrical systems or machinery.
When installing in machines, commissioning of the power feedback
unit (i.e. the starting of operation as directed) is prohibited until it is
proven, that the machine corresponds to the regulations of the EC Di-
rective (2006/42/EG) (Machinery Directive); EN 60204 must be ob-
served.
Commissioning (i.e. starting operation as directed) is only allowed
when there is compliance with the EMC-Directive (2004/108/EG).
The power feedback units meet the requirements of the Low-Voltage
Directive (2006/95/EEC). The harmonized standards of the prEN
50178/DIN VDE 0160 series together with EN 60439-1/DIN VDE
0660 part 500 and EN 60146/DIN VDE 0558 are applicable for the
power feedback unit. The technical data and information on the con-
nection conditions must be obtained from the nameplate and the
documentation and must be observed in all cases.
3.
Transport, Storage
Notes on transport, storage and appropriate handling must be observed
At non-observance any warranty expires.
The power feedback unit has to be protected from inadmissible stress.
The transport is only valid in original packaging and in the thereon by
pictograms marked transport position.
In particular during transport and handling no components are allowed
to be bent and / or isolating distances may not be altered. The units are
equipped with electrostatic sensitive devices, which may be damaged
by improper handling. Therefore it has to be avoided to get in contact
with electronic components. If electronic components are damaged
mechanically the unit must not be put into operation, as it cannot be
ensured, that all relevant standards are observed. Climatic conditions
must be observed according to prEN 50178.
4.
Erection
The devices must be erected and cooled according to the regu-
lations of the corresponding documentation.
The power feedback units must be protected from inappropriate
loads. Particularly during transport and handling, components
must not be bent and / or isolating distances must not be
changed. Touching of electronic components and contacts must
be avoided.
Power feedback units contain electro-statically sensitive com-
ponents which can easily be damaged by inappropriate han-
dling. Electrical components must not be damaged or destroyed
mechanically (health risk are possible!).
5.
Electrical Connection
When working on live power feedback units, the valid national
regulations for the prevention of accidents (e.g. VBG 4) must
be observed. Before any installation or connection works, the
plant has to be switched off and to be secured properly.
The electrical installation must be carried out according to the
appropriate regulations (e.g. cable cross-sections, fuses, PE-
connection). More detailed information is included in the
documentation. When using the power feedback unit with con-
trollers without safe separation from the supply line (to VDE
0100) all control wiring has to be include in further protective
measures (e.g. double insulated or shielded, grounded and insu-
lated).
Notes concerning the installation in compliance with EMC –
such as screening, grounding, arrangement of filters and lying
of cables – are included in the chapter installation of this docu-
mentation. These notes must be also observed in all cases for
power feedback units with the CE-mark. The compliance with
the required limit values demanded by the EMC legislation is
the responsibility of the manufacturer of the system or machine.
6.
Operation
Systems where power feedback units are installed, if applicable,
have to be equipped with additional monitoring and protective
devices according to the valid safety regulations e.g. law on
technical tools, regulations for the prevention of accidents, etc. .
After disconnecting the power feedback unit from the supply
voltage, live parts of the power feedback unit and power con-
nections must not be touched immediately, because of possibly
charged capacitors. For this, observe the corresponding labels
on the drive controllers.
During operation, all covers and doors must be closed.
7.
Maintenance and service
The manufacturer’s documentation must be observed.
This safety information must be kept!
The product-specific safety and application notes in these Op-
erating Instructions must also be observed!

3.1 General safety information
•These safety regulations are not entitled to completeness. In case of questions please
contact our technicians.
•When commissioning the power feedback units are compliant with the state of the
art. The power feedback unit generally allows safe operation.
•The statements of this manual describe the attributes of the products without guaran-
teeing them.
•The power feedback unit may expose persons, the power feedback units itself and
other material to danger, if
– non qualified personal works at and with the power feedback unit.
– The power feedback unit is used in opposite to its purpose.
•Power feedback units have to be projected in a way, that they fulfil their function and
don’t expose persons to danger, if they are mounted correctly and are used in accor-
dance with their purpose. This applies also for the interplay with the whole plant.
•The units, operational data and circuit details described in this manual have to be un-
derstood analogously and have to be checked for transferability to each application.
•For the reasons of personal safety, the observance of the EMC-regulations and for
the regular cooling the operation of the device is only allowed with a closed cover of
the housing and with mounted flanges!
•Use the drive system only in flawless condition.

•Modifications of the power feedback units without consultation of a REVCON
-
technician are not allowed generally.
•The warranty given by us expires, if the unit is modified or (even partially) dismantled
or if it is used in contradiction to our instructions.
•The constructor of the plant, who has to know the technical guidelines, bears the re-
sponsibility for the correct selection and arrangement of the electrical components.
•Putting into operation of the power feedback unit is only admissible at VDE-conform
nets of electrical power supply. Non observance may damage the device!
•In accordance with the corresponding standards and guidelines the operation on even
for a short time over-compensated networks (cosϕ≤1) respectively on un-choked com-
pensation-units is not admissible. If this is done nevertheless, overvoltage will occur
(caused by oscillating currents), which may damage all connected components, espe-
cially electronic units like controllers and power feedback units.
•To low powered or unloaded generators and to regulating transformers it is never al-
lowed to feed back power without a previous consultation of our application depart-
ment. Otherwise unintended voltage rises / excess voltages are generated, which may
damage or destroy REVCON
and combined units!
•Before operating at nets without reference to neutral ground additional safety meas-
ures (e.g. installation of over voltage suppressors like MOV’s) have to be done. If nec-
essary, please ask for technical support by our technicians.

•An undisturbed operation of the power feedback unit is only probable, if the following
instructions are observed. If these instructions are not observed, tripping of the unit
and damages may occur.
•Pay attention to the correct values of mains and DC-bus voltage.
•Separate power and control wires (> 15cm)
•Use shielded or twisted control wires. Connect both ends of the shield to ground!
•When using the digital input devices, only use suitable switching devices, whose
contacts are able to switch the connected voltages.
•Connect the housings of drive, controller and power feedback unit to ground
carefully. Connect shields of power cables to ground at both ends with as big
surface as possible (remove lacquer)!
•Connect the cabinet or the plant by a star-shaped network to ground (ground
loops have to be avoided!)
•The power feedback unit has been designed for a fixed connection to mains only. Es-
pecially when using RFI-filter leakage current values> 3,5mA may occur. The cross
section of the earthing conductor must be at least 10mm² copper, or a second conduc-
tor has to be connected in parallel (star shaped grounding network).
•If components are used, which have no electrical separated inputs / outputs it is neces-
sary to equalize the potentials (e.g. by an equalizing wire). If this is not observed,
these components may be damaged by equalizing currents.
•When carrying out an insulations test in accordance with VDE0100/part 620 the de-
vice has to be disconnected to avoid damage to the power semiconductors. This proce-
dure corresponds with the standard, as each device performs a high voltage test in ac-
cordance with VDE 0160 (EN 50178) in the course of final testing after manufactur-
ing.

•A standard fault-current circuit breaker (sensitive on peak currents) is not allowed to
be used as the only protective measure when using controller and power feedback unit
Caused by a DC-component in the mains current a controller with 3-phase input volt-
age may prevent a fault-current circuit breaker from tripping in case of a earth fault. In
accordance with VDE 0160 a fault-current circuit breaker is not allowed to be used as
the only protective measure. In dependence on the kind of network (TN, IT, TT) fur-
ther protective measures in accordance with VDE 0100 part 410 are necessary. For a
TN-network this may be an over current protection, for an IT-network insulation su-
pervision with pulscode-measurement. For all kind of networks protective insulation (-
transformer) may be used, if required power and length of wires allow that. When se-
lecting a fault current circuit breaker the following measures have to be considered:
•The fault current circuit breaker has to be compliant with the VDE 0664 standard.
•The tripping current should be 300mA or more, to prevent a premature tripping
caused by the leakage current of the controller. In dependence on the load, the
length of the motor cables and the usage of a RFI-filter the leakage current may
even be much higher.
Fault current circuit breakers, which are sensitive to all kinds of leakage currents, grant a
good protection and are suitable as the only protection measurement for one ore three
phase controllers. The connection instructions of the manufacturer have to be observed.

3.5 General instructions
By this information to erectors and users of a plant hints on properties and directions con-
cerning the power feedback unit are given. These hints are not entitled to completeness.
Special features in comparison to a brake chopper:
Unlike a braking resistor a power feedback device isn't a constant drain, but it's dependent
on the momentary characteristics of the supplying net. Commutation brake downs and
voltage-flicker in the net have a considerable effect to the backward current of the device.
In case of a short time voltage brake down the backward current has to raise correspond-
ingly to feedback the demanded power-amount. Does the level of the supply voltage sink
for a longer time; the maximum feedback power is reduced.
If only one phase fails, the device is able to work on, but the current in the two remaining
conductors will rise up to 150% of the normal level.

Length of the DC-connection
The maximum inductivity of the DC-connection between output B6- Bridge of the in-
verter and the power feedback device mustn't exceed a certain level, as this inductivity
inducts an additional voltage to the DC-bus, when the IGBT’s are switched off. To avoid
an overload to the components of the power feedback unit, this additional voltage must
not exceed 100V. Resulting from this and other relevant characteristics of the power
feedback unit (DC-capacity and absolute maximum value of the grid current) the maxi-
mum inductivity can be calculated.
This inductivity always has to be higher or equal than the sum of the DC-bus inductivity
of the frequency inverter and the conductor inductivity of the DC connection.
The DC-bus inductivity of the frequency inverter has only to be considered, if it is placed
between the inverter B6- Bridge and the power feed-back unit. The cables, which are
normally used for power applications, have an inductance per unit length of about
0,6µH/m. If the values of the input capacitance C, the during power feedback maximum
