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 exist
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.
OnlyQualied
Electro-Perso-
nnel
All work from the transport, to installation and start-up as well as maintenance may only be
donebyqualiedpersonnel(IEC364and/orCENELECHD384andIEC-Report664and
notenationalsafetyregulations).Accordingtothismanualqualiedstaffmeansthosewho
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
eldofpowertransmission.
Observe Stan-
dards
The COMBIVERT R6 must not be started until it is determined that the installation com-
plieswith2006/42/EC(machinedirective)aswellastheEMCdirective(2004/108/EC)(note
EN60204).
TheCOMBIVERTR6meetstherequirementsoftheLow-VoltageDirective2006/95/EC.The
harmonizedstandardoftheseriesEN61800-5-1(VDE0160)isused.
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
besecuredagainstimpactinuence.Observethemarkingonthenalpacking!Afterremovingthenalpacking
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 elec-
trostatically endangered components which can be destroyed by inappropriate handling. For
that reason the contact of electronic components and contacts is to be avoided. The equip-
ment 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.

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 the EN requirements are met. With frequency inverters that are not isolated from the
supplycircuitallcontrollinesmustbeincludedinotherprotectivemeasures(e.g.double

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.
• Installpowercablesandcontrolcablesseparately(>15cmseparation).
• 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
groundterminal.Removepaintnishwherenecessary.
• Ground the cabinet or the system earth star point with the shortest connection to mains
earth(avoidearthloops)
• UseexclusivelythecommutationreactorspeciedbyKEB.
• 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
supplyoperation(seetechnicaldata).
Automatic Re-
start
The COMBIVERT R6 can be adjusted by such way that the inverter restarts automatically
afteranerrorcase(e.g.brokenphaseline).Systemdesignmusttakethisintoaccount,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
!IftheI2t-protection
is adapted with a gR fuse, a conditional protection at supply input is possible. The short-
circuit protection at DC output is ensured by internal or external aR respectively gR fuses.
Conditionally

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-phaseinverters(withB6bridge-connectedrectier)byRCMA’swithseparation(used
privileged)orRCD’stypeB(all-currentsensitiveFI’s)
The tripping current should be 300mA or more, in order to avoid a premature triggering by
dischargecurrents(about200mA.Dependentontheload, the length of themotorcable
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.
Dependentontheavailablemainsform(TN,IT,TT)furtherprotectivemeasuresareneces-
saryinaccordancewithVDEPart4104(Part4;Chapter41).
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!

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 information can be taken from the provided documentation. Which ferrite ring
shall be used is dependent on the used cable cross-section.

4.3.1 General description of inverter input terminals
Starting current limiting
WhenconnectinginverterstoaDCbuspayattentiontotheinternalwiringoftheDCvoltageinputs!
Inverters that directly output the DC link bus to the DC terminals must be integrated into the DC bus by
waythatthesupplyunit(s)limitthestartingcurrent.Theprechargingmustbecompletedwithintense-
conds.10
Maximum DC link capacity
The maximum DC link capacity can be calculated by adding the DC link capacities of all inverters in the
DCbus.Atableforthiscanbefoundintheappendix.Thesupplysource(supplyunitorinverterwithAC

This type can be supplied by mains
and by DC circuit. The starting current
limitation is designed after the input
terminals. When used as output par-
allel connected inverters must have
an own starting current limiting at the
DC voltage input.
This type can be supplied by mains.
In consideration of the DC link capaci-
ty the DC voltage terminals can be
used as output. When used as input
ensure that the starting current is
externally limited.
This type is only a DC inverter with
starting current limiting. The DC in-
verter can be combined with all other
types in consideration of the maxi-
mum DC link capacity.
