1.5 Speciedapplication
The COMBIVERT R6-N serves exclusively for the supply of frequency inverters with DC input
and/or regeneration of excess energy into the supply system. The operation of other electrical
consumers is prohibited and can lead to malfunctions or to the destruction of the units.
The used semiconductors and components of the KEB Automation KG are developed and di-
mensioned for the use in industrial products. If the KEB COMBIVERT F5 is used in machines,
which work under exceptional conditions or if essential functions, life-supporting measures or
anextraordinarysafetystepmustbefullled,thenecessaryreliabilityandsecuritymustbe
ensured by the machine builder.
The operation of our products outside the indicated limit values of the technical data leads to
the loss of any liability claims.
All output functions of the R6 are "one-channel according to ISO 13849, no diagnostic cov-
erage and therefore not safe". If required, additional protective measures must be met by the
user.
1.5.1 Standard operation
If the DC link voltage increases to a value above the peak value of the mains voltage (nega-
tive power), regeneration of the current into the mains occurs automatically. The regenerative
levelisdenedwithparameterCP.34orcS.02.Themainsvoltageisanalogmeasured.The
regenerativecurrentisequaltothefeed-in,wherebythecurrentowperiodscorrespondto
the times of a B6 bridge circuit. Regeneration is completed if the regenerative and puls off
level (CP.32 or cS.06) is fallen below.

Preface
1.5.2 Abnormal operation
When exceeding the permissible limit values for voltage, current or temperature the current
owbetweenDClinkandmainsisblockedduringregeneration.Anappropriateerrormes-
sage is also displayed during supply. The unit must be disconnected from the supply system
or the load must be switched off in case of overcurrent or overload. This can be done by
opening the control release of the frequency inverter.
At factory setting the modulation is switched off in case of a net phase failure and error mes-
sage E.nEt is displayed.
Special adjustments from KEB are necessary if the modulation and/or the standard operation
shouldstartagainwithinadenedtimeincaseofreturnofpowersupply.

2. Safety Instructions
2.1 General instructions
Danger Electric Shock
COMBIVERT R6 power supply and regenerative units contain dangerous
voltages which can cause death or serious injury.
COMBIVERT R6 can be adjusted by way that energy is regenerated into the
supply system in case of power failure at regenerative operation. Therefore
a dangerous high tension can exist in the unit after switching off the supply
system.
Before working with the unit check the isolation from supply by meas-
urements in the unit.
Care should be taken to ensure correct and safe operation to minimise risk
to personnel and equipment.
Warning OnlyQualiedElectro-Personnel
All work from the transport, to installation and start-up as well as mainte-
nancemayonlybedonebyqualiedpersonnel(IEC364and/orCENELEC
HD 384 and IEC-Report 664 and note national safety regulations). According
tothismanual qualied staffmeans those whoareabletorecogniseand
judge the possible dangers based on their technical training and experience
and those with knowledge of the relevant standards and who are familiar with
theeldofpowertransmission.
Attention Observe standards
The COMBIVERT must not be started until it is determined that the installa-
tion complies with the Machine directive (2006/42/EC) as well as the EMC-di-
rective (2004/108/EC)(note EN 60204).
The COMBIVERT meets the requirements of the Low-Voltage Directive
2006/95/EC. The harmonized standard of the series EN 61800-5-1 (VDE
0160) is used.
This is a product of limited availability in accordance with IEC 61800-3. This
product may cause radio interference in residential areas. In this case, the
operator must take appropriate measures.
11
Safety Instructions

2.2 Transport, storage and installation
The storage of the COMBIVERT must be done in the original packing. It is to be protected
against humidity and excessive cooling and thermal effect. A long-distance transport must be
carriedoutintheoriginalpacking.Itistobesecuredagainstimpactinuence.Observethe
markingonthenalpacking!AfterremovingthenalpackingtheCOMBIVERTmustbeshut
down on a stable base.
Warning Protect Against Accidental Contact
The COMBIVERT R6 must be protected against invalid loading. Components and covers
must not be bent or moved as this may affect insulation distances. The units contain electro-
static sensitive devices which can be destroyed by inappropriate handling. For that reason
the contact of electronic devices and contacts is to be avoided. The equipment must not be
switched on if it is damaged as it may no longer comply with mandatory standards.
Make sure that during installation there is enough minimum clearance and enough cooling.
Climatic conditions must be observed in accordance with the instruction manual.
Warning Hot surface
Heat sinks can reach temperatures, which can cause burns when touching. If
in case of structural measures a direct contact cannot be avoided, a warning
notice "hot surface" must be mounted at the machine.
2.3 Electrical connection
Danger Observe capacitor discharge time
Before any installation and connection work, the system must be switched off and secured.
After clearing the DC link capacitors are still charged with high voltage for a short period of
time. The unit can be worked on again, after it has been switched off for 5 minutes.
Caution Safe isolation
The terminals of the control terminal strip are securely isolated in accordance with EN 61800-
5-1. With existing or newly wired circuits the person installing the units or machines must
ensure that the EN requirements are met. With frequency inverters that are not isolated from
the supply circuit all control lines must be included in other protective measures (e.g. double
insulation or shielded, earthed and insulated).
12
Safety Instructions

Danger Voltage with respect to ground
The connection of COMBIVERT R6 is allowed to:
a) symmetrical mains with a voltage phase (L1, L2, L3) with respect to neutral conductor/
ground (N/PE) of maximum 305 V.
b) phase conductor grounded supply networks:
• the control system is no longer regarded as “safe isolated circuit”, further protection
measures are required therefore (see "Safe isolation").
• with this type of power system, the max. voltage phase / earth must not exceed 528 V
absolute
• appropriate, external DC fuses at the DC connections are necessary for the 400 V class.
Use the COMBIVERT R6-N without internal DC fuses.
• ContactKEBregardingEMClter.
Attention Fixed connection
TheCOMBIVERTR6isdesignedforxedconnection,sincedischargecurrentsof>3.5mA
occurespeciallywhenusingtogetherwithEMIlters.Therefore,therequirementsorinstruc-
tions from EN 60204-1 (VDE 0113) and EN 61800-5-1 (IEC 0160-5-1) must be observed.
Caution Insulation measurement
When doing an insulation or voltage measurement in accordance with in EN 60204-1 /
VDE0113-1,thepowersemiconductoroftheunitandexistingradiointerferenceltersmust
be disconnected because of the danger of destruction. This is permissible in compliance
with the standard, since all inverters are given a high voltage test in the end control at KEB.
In the case of special requirements please contact KEB.
Caution Different earth potentials
When using components without isolated inputs/outputs, it is necessary that equipotential
bonding exists between the components to be connected (e.g. through the equalizer). Dis-
regard can cause destruction of the components by the equalizing currents.
13
Safety Instructions

Caution Prevent malfunctions
A trouble-free and safe operation of the COMBIVERT R6 is only guaranteed when the con-
nection instructions below are strictly followed. Incorrect operation or damage may result
from incorrect installation:
• Pay attention to mains voltage.
• Install power cables and control cables separately (>15 cm separation).
• Useshielded/twistedcontrollines.LayshieldatonesidetoCOMBIVERTR6-NtoPE!
• Only use suitable circuit elements to control the logic and analog inputs, whose contacts
are rated for extra-low voltages.
• Housing of the COMBIVERT R6 must be well earthed. Screens of larger power cable
must be directly and securely attached to both the inverter PE terminal and the motor
ground terminal (remove paint).
• Ground the cabinet or the system earth star point with the shortest connection to mains
earth. (avoid earth loops)
• UseexclusivelythelinecommutationthrottlespeciedbyKEB.
• The average value of the supplied DC current may not exceed the maximum DC current.
• If several frequency inverters are connected to the COMBIVERT R6-N the max. permis-
sible DC link capacities of all connected frequency inverters must be considered during
supply operation (see technical data).
Warning Automatic restart
The COMBIVERT R6 can be adjusted by such way that the inverter restarts
automatically after an error case (e.g. broken phase line). System design
must take this into account, if appropriate, and additional monitoring or pro-
tective features added where necessary.
Caution Not short-circuit proof (supply)
TheCOMBIVERTR6isnotshort-circuitproofatthemainsinput!Conditionalprotectionat
the mains input is possible if the I2t-protection was adapted with a gR fuse. The short-circuit
protection at DC output is ensured by internal or external aR respectively gR fuses.
Caution Conditionally short-circuit proof (regeneration)
The COMBIVERT R6 is conditionally short-circuit proof (EN61800-5-1 / VDE 0160). The
intended function is guaranteed after resetting the internal protection devices.
Exception:
• If earth- or short circuits often occurs at the output, this can lead to a defect in the unit.
14
Safety Instructions

Attention Cyclic activation and deactivation
With applications requiring the COMBIVERT R6 to be switched on and off cyclically, main-
tain an off-time of at least 5 min. If you require shorter cycle times please contact KEB.
Switchingoffduringtheinitializationphasecancauseundenedconditions.
Attention RCD (residual current operated circuit-breaker)
When using systems with RCD, the instructions or the requirements of VDE 0100 -T530
(IEC 60364-5) must be observed. The recommended tripping current of the RCD type „B“ is
300 mA.
15
Safety Instructions

2.4 EMC instructions
COMBIVERT R6-N represent electrical equipment designed for use in industrial and com-
mercial units. In accordance with the EMC directive 2006/108/EC, it is not obligatory to mark
these devices as they represent components to be further processed by the respective ma-
chine and unit manufacturer and are not operable independently according to the EMC di-
rective. The person installing / operating the machine / unit is obliged to prove the protective
measures demanded by the EMC directive are complied with. The prescribed ratings can
usuallybecompliedwithwhenusingtheradiointerferencevoltageltersspeciedbyKEB,
and when observing the following measures and installation guidelines.
2.5 EMC conform installation
TheCOMBIVERTR6isdesignedtobeusedinthesecondenvironmentasdenedinEN
61800-3(unitwithitsownsupplytransformer).Takeadditionalltermeasureswhenusing
itintherstenvironment(residentialandcommercialareaconnectedtopubliclow-voltage
mains)!
• Install the control cabinet or system in an appropriate and correctly way (see chapter „EMC
conform control cabinet installation“)
• To avoid coupled-in noise, separate supply lines, motor lines, control and data lines (low-volt-
age level < 48 V) and leave a space of at least 15 cm between them when installing.
• In order to maintain low-resistance high frequency connections, earthing and shielding,
as well as other metallic connections (e.g. mounting plate, installed units) must be in met-
al-to-metal contact with the mounting plate, over as large an area as possible. Make ground
connections with a surface as large as possible (earthing strips).
• Only use shielded cable with copper or tin-plated braid, since steel braid is not suitable for
high frequency ranges. The screen must always be installed on the compensating rail and
fastened with clips or guided through the wall of the housing. Do not elongate the screen
end(pigtails)withindividualconductors!
• Ifexternalinterferencesuppressionltersareused,thenthesemustbeinstalledasclose
as possible to (<30 cm from) the interference source and in metal-to-metal contact with the
mounting plate, over as large an area as possible.
• Always equip inductive control elements (contactors, relays etc.) with suppressors such as
varistors, RC-elements or damping diodes.
• All connections must be kept as short as possible and as close as possible to the earth, as
freeoatinglinesworkasactiveandpassiveaerials.
• Keep connection cables straight (do not bundle). Install a non-assigned wire at one sides to
the protective earth conductor.
• Theowandreturncircuitmustbetwistedwhenthelines are not shielded, inorder to
dampen common-mode noise.
• Further information can be found in the internet, see „www.keb.de“.

Warning General instructions
•
Voltagestabilizationmustbeactivatedatthefrequencyinverterifaharmoniclterisused.
•The units are not short-circuit proof without corresponding dimensioned fuses.
•Exceeding of the max. rechargeable DC link capacity can lead to a defect.
•A load removal in the DC link circle may be done only after the message „ready“.
•If the control release is set when switching off the mains, this can lead to an overcurrent error and the
lifetime of the module can be reduced.
•The unit must be disconnected from the supply system or the load must be switched off in case of overcur-
rent or overload.
