1.5 EC-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 tech-
nical standards and certification procedures within the European Community. At the mo-
ment there are 21 EC-Directives for product sectors. The directives are or will be convert-
ed 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-mark themselves are compliant with the Low-Voltage Di-
rective only. For observing the EMC Directive recommendations are made.
1.5.1 EC-low voltage directive
(73/23/EEC)
Modified by: CE – Marking Directive (93/68/EEC)
CE – Marking Directive (2006/95/EEC)
General:
•The Low-Voltage Directive is valid for all electrical equipment which is used at a nominal
voltage between 50V and 1000V AC and between 75V and 1500V DC together with cus-
tomary environment conditions. Excluded is e.g. the use of electrical equipment in explo-
sive areas and electrical components of lifts for persons or material.
•Aim of the Low-Voltage Directive is to put only those products into commerce which
don’t endanger the safety of persons and animals as well as the preservation of material as-
sets.

2Safety information
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, in-
correct installation or operation, creates the risk of severe injury to
persons or damage to material assets.
Further information can be obtained from the documentation.
All operations concerning transport, installation and commission-
ing as well as maintenance must be carried out by qualified,
skilled personnel (IEC 364 and CENELEC HD 384 or DIN VDE
0100 and IEC-Report 664 or DIN VDE 0110 and national regula-
tions for the preventions of accidents must be observed).
According to this basic safety information qualified skilled per-
sonnel are persons who are familiar with the erection, assembly,
commissioning and operation of the product and who have the
qualifications necessary for their occupation .
2. Application as directed
Power feedback units are components which are designed for in-
stallation in electrical systems or machinery.
When installing in machines, commissioning of the power feed-
back 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 Directive (2006/42/EG) (Machinery Directive); EN
60204 must be observed.
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 ap-
plicable for the power feedback unit. The technical data and in-
formation on the connection conditions must be obtained from the
nameplate and the documentation and must be observed in all cas-
es.
3. Transport, Storage
Notes on transport, storage and appropriate handling must be ob-
served.
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 there-
on by pictograms marked transport position.
In particular during transport and handling no components are al-
lowed 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 regula-
tions 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 ap-
propriate regulations (e.g. cable cross-sections, fuses, PE-
connection). More detailed information is included in the docu-
mentation. When using the power feedback unit with controllers
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 insulated) .
Notes concerning the installation in compliance with EMC – such
as screening, grounding, arrangement of filters and laying of ca-
bles – are included in the chapter installation of this documenta-
tion. These notes must be also observed in all cases for power
feedback units with the CE-mark. The compliance with the re-
quired limit values demanded by the EMC legislation is the re-
sponsibility 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 Oper-
ating Instructions must also be observed!

2.1 General safety information
•These safety regulations are not entitled to completeness. In case of questions please
contact our technicians.
•When commissioning the power feedback unit is 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 units are 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 accord-
ance 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
measures (e.g. installation of over voltage suppressors like MOV’s) have to be done. If
necessary, 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, the-
se 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 an insulation
supervision with pulscode-measurment. 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.

experience, education, their knowledge in relevant norms, directives, accident directives and op-
eration conditions to execute the necessary works and to recognize possible danger and to avoid
it. (Definition of qualified staff IEC 364)
Intended Use
Danger!
Power feedback units are electrical drive components, which are directed to be installed in
electrical plants or machines. They have to be used only for drive systems with infinity variable
speed controls of 3-phase asynchronous or permanent magnet motors. The usage with other elec-
trical loads is not permitted and may damage the devices. The power feedback unit may only be
connected to symmetrical networks. Non-observance may damage the devices.

2.6 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 frequen-
cy converter and the power feedback device must not exceed an assigned value, as this in-
ductivity inducts an additional voltage to the DC-bus of the frequency converter, 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 maximum inductivity can
be calculated:
The maximal valid line inductance for the power feedback unit and the coupling induct-
ance between the two conductors produce at a by the current carrying capacity-defined
cross section of the lead of the cable a maximum length of the connecting cable:
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 nor-
mally used for power applications, have an inductance per unit length of about 0,6µH/m.
