1.2 Product description
This instruction manual describes the power supply and regenerative unit KEB COMBIVERT
R6-S. The COMBIVERT R6-S has the following features.
The supply unit
converts a three-phase input voltage into DC voltage.•
supplies KEB frequency inverter individually or via DC interconnection.•
can be parallel connected if higher power supply is required.•
increases the stability of the DC link voltage in the DC interconnection.•
The regenerative unit
feeds back the excess energy from generatoric operation into the supply system.•
reduces the energy demand.•
reduces the heat emission.•
is environmentally friendly and space-saving.•
replaces braking resistor and braking transistor.•
is cost-saving.•
The COMBIVERT R6-S is generally protected against overcurrent, ground fault and tempera-
ture. Appropriate dimensioned DC fuses protects the DC link circuit against short-circuit. The
following accessories are necessary for operation with the COMBIVERT R6-S:
Mains choke•
HF 󰘰lter (for observance of EMC standard)•

GB - 5
Preface
1.3 Speciedapplication
The COMBIVERT R6-S serves exclusively for the supply of frequency inverters with DC input
and/or feedback 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.
1.3.1 Standard operation
If the DC link voltage increases to a value above the peak value of the mains voltage (negative
power), feedback of the current into the mains occurs automatically. The mains voltage is ana-
log measured. The feedback occurs in a square-wave format, whereby the current 󰘱ow period
corresponds to the times of a B6 bridge circuit. The feedback is 󰘰nished if the DC link voltage
decreases the supply peak voltage (positive power).
1.3.2 Abnormal operation
When exceeding the permissible limit values for voltage, current or temperature the current
󰘱ow between DC link and mains is blocked during recovery. An appropriate error message is
also displayed during supply. The unit must be disconnected from the supply system or the
load must be switched o󰘯 in case of overcurrent. This can be done by opening the control re-
lease of the frequency inverter.
At factory setting the modulation is switched o󰘯 in case of a net phase and/or a synchronisation
line failure and the error message 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.

Safety Instructions
2. Safety Instructions
2.1 General instructions
Electric Shock
COMBIVERT R6 power supply und regenerative units contain dangerous voltages which
can cause death or serious injury.
COMBIVERT R6 can be adjusted by way that energy is refeed into the supply system in
case of power failure at generatoric operation. Therefore a dangerous high tension can be in
the unit after switching off the supply system.
Before working with the unit check the isolation from supply by measurements in the
unit.
Care should be taken to ensure correct and safe operation to minimise risk to personnel and
equipment.
OnlyQualied
Electro-Perso-
nnel
All work from the transport, to installation and start-up as well as maintenance 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.
Observe Stan-
dards
The COMBIVERT R6 must not be started until it is determined that the installation com-
plies with 2006/42/EC (machine directive) as well as the EMC directive (2004/108/EC) (note
EN60204).
TheCOMBIVERTR6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 may need to take
corresponding measures.
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.Themarkingonthenalpackingmustbeobserved!Afterremovingthenal
packing the COMBIVERT must be set down on a stable base.
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.
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.

Safety Instructions
2.3 Electrical connection
Note 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.
Secure
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).
Voltage With
Respect To
Ground
Connection of the COMBIVERT R6 is only permissible on symmetrical networks with a maxi-
mumlinevoltage(L1,L2,L3)withrespecttoearth(N/PE)of317V.Anisolatingtransformer
mustbeusedforsupplynetworkswhichexceedthisvalue!Theunitsmaybedamagedif
this is not observed.
Earthed Exter-
nal
Conductor
The COMBIVERT R6 can be connected to power systems with earthed external conductors
(e.g. delta power systems) if the following exceptions apply:
the control system is no longer regarded as “safe isolated circuit”, further protection•
measures are required therefore
with this type of power system, the max. voltage phase / earth must not exceed 550 V•
absolute
external DC fuses at the DC connections are necessary for the 400 V class. Use the•
COMBIVERT R6-S without internal DC fuses.
Only Fixed
Connection
TheCOMBIVERTR6isdesignedforxedconnectiononlyasdischargecurrentsof>3.5
mAmayoccurespeciallywhenusingEMIlters.Thereforeitisnecessarytolayaprotective
conductor with a section of at least 16mm2 (copper) or a second protective conductor in
compliance with EN
61800-5-1. Ground point-to-point with the shortest connection possible
to mains earth (avoid earth loops).
Insulation Mea-
surement
When doing an insulation measurement in accordance with VDE 0100 / Part 620, the po-
wer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 accordance with
EN 50178.
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). Disre-
gard can cause destruction of the components by the equalizing currents.

Safety Instructions
Prevent
Disturbances
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-S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 COMVIBERT R6-S the max. permis-•
sible DC link capacities of all connected frequency inverters must be considered during
supply operation (see technical data).
Automatic Re-
start
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 protective features added where necessary.
Not Short-Cir-
cuit Proof
(Supply)
The COMBIVERT R6 is not short-circuit proof at the power supply input
!IftheI2t-protection
is adapted with a gR fuse, a conditional protection at supply input is possible. If necessary
the short-circuit protection at DC output is ensured by internal aR fuses.
Conditionally
Short-Circuit
Proof
(Feedback)
The COMBIVERT R6 is conditionally short-circuit proof (EN 61800-5-1 / VDE 0160). After
resetting the internal protection devices, the function as directed is guaranteed.
Exception:
•Ifanearth-leakagefaultorshort-circuitoftenoccursattheoutput,thiscanleadtoa•
defect in the unit.
Cyclic Activati-
on And Deacti-
vation
With applications requiring the COMBIVERT R6 to be switched on and off cyclically, maintain
an off-time of at least 5 min. If you require shorter cycle times please contact KEB.

Safety Instructions
RCD (Residual
Current Ope-
rated Circuit-
Breaker)
If personnel protection of the system is required, the COMBIVERT R6-S must be protected
according to EN 61800-5-1:
•3-phaseinverters(withB6bridge-connectedrectier)byRCMA’swithseparation(used•
privileged)orRCD’stypeB(all-currentsensitiveFI’s)
The tripping current should be 300mA or more, in order to avoid a premature triggering by
discharge currents (about 200mA. Dependent on the load, the length of the motor cable
and the use of a radio interference lter, substantially higher leakage current can occur.
The connection instructions from the manufacturer and the valid local reqirements must be
observed.
Dependent on the available mains form (TN, IT, TT) further protective measures are neces-
sary in accordance with VDE Part 410 4 (Part 4; Chapter 41).
For example, with TN-mains this protection is made with overcurrent protective devices,
with IT-mains it is insulation monitoring with a pulse-code measuring method. A protective
separation can be used with all mains forms as long as the required power and cable lengths
permit this.
The person setting up the unit must present proof of compatibility before installing the inver-
ter!

mercialareaconnectedtopubliclow-voltagemains)!
Install the control cabinet or system in an appropriate and correctly way (see chapter „control cabinet instal-•
lation“)
To avoid coupled-in noise, separate supply lines, motor lines, control and data lines (low-voltage level < 48V)•
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 metal-•
lic connections (e.g. mounting plate, installed units) must be in metal-to-metal contact with the mounting plate,
over as large an area as possible. Use earthing and equipotential lines with a section as large as possible
(min. 16mm2) or use thick earthing strips.
Only use shielded cable with copper or tin-plated braid, since steel braid is not suitable for high frequency ran-•
ges. 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!

1) The overcurrent is specied for 1 minute. The overload cycle is 300 seconds. This corresponds to duty class 2 EN 2‑60146‑1.
2) The current data are based on a fundamental frequency component of g=0,95. The fundamental frequency component or the effective value of
the input current is dependent on load and line supply conditions. At uncontrolled B6 converters the phase angle cosφ1 can be set to one, so the
value of the fundamental frequency components is equal to the value of the power factor.
3) If the DC‑infeed current > 85 A DC use two by two of the DC terminals (++ and ‑‑) to meet the requirements of the UL standard. The connection
cables are parallel connected.
4) Please contact KEB for higher values.
Voltage stabilization must be activated at the 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“.

3.5.4 Ferrite rings
Ferrite rings are used for the reduction of the cable-based and radiated interferences. For a high
damping, the ferrite rings are attached as close as possible to the interference source, i.e. at the DC
and at the motor output terminals of the frequency inverter. The conductors must passed through the
ferrite core for the use as current-compensated choke. PE must be passed outside. Further informa-
tion can be taken from the provided documentation. Which ferrite ring shall be used is dependent on
the used cable cross-section.

1) Current sharing between R6‑S and frequency inverter must be observed during supply operation. The current sharing is depending on the uk‑
value and the rated current of the mains chokes /commutation chokes (see formula below). A mains choke with uk=4 % is mandatory required
for reduction of circulating currents.
2) The regenerative contactor may only be connected if the precharging in the DC link circle of the inverter is completed. If the precharging of R6‑S
and frequency inverter is in the same DC branch, regenerative contactor are eventually not necessary (depending on the charging resistors
and the DC link capacity).
3) Parallel connection of the frequency inverter and R6‑S causes a circulating current in regenerative operation. It is depending on the inductance
of the mains‑/ commutation chokes. The entire regenerative power is 75... 90 % of the R6‑S regenerative power.
4) The cable cross‑section may not be smaller than 10 mm². It must be dimensioned for the DC rated current of the load. Otherwise there are fuses
in the DC link circle (10) necessary The indicated maximum protection for the connected frequency inverters must be observed !
