Introduction

1.3 Validity and liability
Application and use of our units in the target products is outside of our control and therefore is exclu-
sively the responsibility of the machine manufacturer.
The information contained in the technical documentation, as well as any user-specic advice in spoken and
written communication are made to best of our knowledge and information about the application. However, they
are considered for information only without responsibility. This also applies to any violation of industrial property
rights of a third-party.
Selection of our units in view of their suitability for the intended use must be done generally by the user.
Inspections and tests can only be done by the machine manufacturer within the framework of the application.
Inspections and tests must be repeated, even if only parts of hardware, software, or the unit adjustment are
modied.
Unauthorized opening and improper tampering can lead to bodily injuries or liability issues and this causes loss
of the warranty. Only use original spare parts and authorized accessories by the manufacturer. The use of other
parts excludes liability for the consequences arising out of such use.
The suspension of liability is valid also for shutdown damages, lost prot, data loss, or other consequential dam-
ages. This is also valid if we have referred to the possibility of such damages.
Should any part of this agreement be invalid for any reason, it is to be replaced with a corresponding text, which
is valid and equivalent to the intended meaning. The rest of the agreement shall remain unaffected and valid.
1.4 Copyright

1.5 Specied application
The COMBIVERT R6-S serves exclusively for the supply of frequency inverters with DC input and/or regenera-
tion of excess energy into the supply system. The operation of other electrical loads is prohibited and can lead
to malfunctions or destruction of the unit.
The used semiconductors and components of KEB are developed and dimensioned for use in industrial prod-
ucts. If the product 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 manufacturer. The operation of our products outside the indicated limit values of the
technical data leads to the loss of any liability claims.
All control card outputs of the R6 are „one-channel, no diagnostic coverage and therefore not safe“ according to
ISO 13849. If required, additional protective measures must be met by the user.
1.5.1 Standard operation
If the DC Bus voltage increases to a value above the peak value of the line voltage (negative power), regeneration
of the current to the line occurs automatically. The line voltage is measured by the R6 unit. Regeneration
occurs in a square-wave format, whereby the current ow period corresponds to the line frequency and the
normal conduction times of a standard 6 pulse bridge rectier circuit. Regeneration stops if the DC bus voltage
decreases below the line supply peak voltage (positive power).
US - 7
Introduction

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 message 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 message E.nEt is dis-
played.
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.

Introduction

2. Safety Instructions
2.1 General instructions
CAUTION
- Risk of
Electrical
Shock
The COMBIVERT R6 power supply and recovery unit contains dangerous voltages which can
cause death or serious injury.
The COMBIVERT R6 can be adjusted such that energy is returned to the line supply system
even in case of power failure during generator operation. Therefore dangerous high voltage
can exist in the unit even after disconnection from the line supply system.
Before working with the unit always verify the voltage has dropped to a safe value by
measuring both the DC bus voltage and the AC line voltage at the R6 unit.
Care should be taken to ensure correct and safe operation and to minimize risk to personnel
and equipment.
Only quali-
ed electro-
personnel
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 personnel means those who
are able to recognize and judge the possible dangers based on their technical training and
experience as well as those with knowledge of the relevant standards and who are familiar
with the eld of power transmission or conversion.
Observe
standards
The COMBIVERT R6 must not be started until it is determined that the installation complies with
89/392/EEC (machine directive) as well as the EMC-directive (89/336/EEC)(note EN60204),
the US - NEC, and the OSHA machine safety code.
The COMBIVERT R6 meets the requirements of the Low-Voltage Directive 73/231/EEC. The
harmonized standard of the series EN 61800-5-1 (VDE 0160) is used.
This is a product of limited interference susceptibility in accordance with IEC 61800-3. This
product may cause radio interference in residential areas. In this case the installer/operator
may need to take corresponding measures.
2.2 Transport, storage and installation
The storage and transport of the COMBIVERT must be done in the original packing. It is to be protected against
humidity and excessive cooling and thermal effects. Long-distance transportation must be carried out in the
original packing. It is to be secured against physical impact and shock during transport. Verify the packaging for
signs of mishandling before removal from the packaging. Contact the shipper in case of damage. After removing
the nal packing, the COMBIVERT R6 must be mounted on a stable mounting base.
Protect
Against
Accidental
Contact
The COMBIVERT R6 must be protected against abnormal operation. Components and
covers must not be bent or moved as this may affect insulation distances. The units contain
electrostatically endangered components which can be destroyed by inappropriate handling.
For that reason the contact of electronic components and circuit boards 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 during installation there is at least the minimum clearance and enough cooling.
Climate conditions must be observed in accordance with this instruction manual.
Hot surface
Heatsinks can reach high temperatures, which can cause burns when touched. A warning
notice “hot surface” must be mounted on the machine control panel if direct physical contact
with the heatsink can not be avoided.
US - 9
2. 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 switch off, the intermediate circuit capacitors are still charged with high voltage for a
short period of time. The unit can be worked on 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. When used together with frequency inverters
that are not isolated from the supply circuit, all control lines must be secured by 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
maximum line voltage (L1, L2, L3) with respect to ground (N/GND) of 305V. An isolating
transformer must be used for networks which exceed this value! The unit may be damaged
if this is not observed.
Grounded Delta
Supply
Connection of the R6 series inverters to voltage systems congured as a corner grounded
delta, center tap grounded delta, open delta, or ungrounded delta may defeat the internal
noise suppression of the inverter. Increased high frequency disturbance in the controller
and on the line may be experienced. A balanced, neutral grounded wye connection
is required. The three phase voltage imbalance must be less than 2% phase-to-phase.
Greater imbalance can lead to damage of the inverter's power circuit.
It is acceptable to use a transformer with a WYE connection on the secondary.
Example of a center grounded wye transformer:
x1x2
x3
x0
Stationary
connection
The COMBIVERT R6 is designed for xed connection only as high frequency ground
leakage currents of > 3.5 mA may occur especially when using EMI lters. It is therefore
necessary to use a ground conductor with a section of at least a #4 AWG (16mm2) copper
conductor or a second ground conductor in compliance with EN 61800-5-1. Ground point-
to-point with the shortest connection possible to the main ground point in the system (avoid
ground loops).
Insulation
Measurement
When doing a high voltage insulation measurement in accordance with VDE 0100 / Part
620, 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 units are given a high voltage test during the quality testing at KEB
in accordance with EN 50178.
US - 10
2. Safety Instructions

Different
Ground Po-
tentials
When using components without isolated inputs / outputs, it is necessary that equal potential
bonding exist between the components to be connected (e.g. through the equalizer). Disregard
can cause destruction of the components by the equalizing currents.
Fuse Sizing
with Isolation
Transformer
When the R6 unit is supplied through an isolation transformer, the maximum allowable fuse
size is dictated by the size of the transformer as dened in the National Electric Code (NFPA-
70 or CSA 22.1). As per Article 450-3(B) of NFPA-70 (similar statements can be found in CSA
22.1), the max fuse size is dened in table 450.3(B) with a rating not greater than 125% of
the rated secondary current. In the case of multiple secondaries, it is the rated value of the
winding which the unit is supplied from. In this case it is to be assumed that the end customer
will fuse the transformer primary side with fuses exceeding 125% of transformer rated input
current. The value of this secondary fuse may be less than the max fuse value listed in the
technical data section 3.1 of this manual. The fusing of the transformer supercedes the fuse
rating of the unit because the value required for the transformer is lower than the max value
with which the unit was tested.
Prevent
disturbances
Trouble-free and safe operation of the COMBIVERT R6 is only guaranteed when the
connection instructions below are strictly followed. Incorrect operation or damage may result
from incorrect installation.
• Pay attention to the line supply voltage.
• Supply connection must be a symmetrical, center-grounded wye.
• Install power cables and control cables separately (>6.0 inches (15 cm) separation).
• Use shielded / twisted control lines. Connect the shield at one end to the COMBIVERT
R6-S GND terminal!
• Only use suitable circuit elements to control the logic and analog inputs, whose contacts
are rated for extra-low voltages.
• The heatsink of the COMBIVERT R6 must be well grounded. Shields of large power
cables must be directly and securely attached to both the inverter GND terminal and the
motor ground terminal. Remove paint nish where necessary.
• Ground the cabinet or the system with the shortest connection to the main ground point
(avoid ground loops)
• Use exclusively the commutation choke or harmonic lter 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, the maximum
permissible DC bus capacities of all connected frequency inverters must be considered
during supply operation (see technical data).
• A ferrite ring must be installed over both + and - DC bus connections to the
COMBIVERT R6 unit to limit common mode noise on the DC bus.
Automatic
Restart
The COMBIVERT R6 can be adjusted in such a way that the unit will restart automatically
after an error (e.g. single phase brown out or loss). System design must take this into account.
If appropriate, additional monitoring or protective features should be added where necessary.
Not Short-
Circuit Proof
(Supply)
The COMBIVERT R6 is not short-circuit proof as a power supply input ! If the I2t - protection is
adapted with a class gR fuse, a conditional protection at supply input is possible. If necessary
the short-circuit protection at DC output is ensured by internal class aR fuse.
US - 11
2. Safety Instructions

Conditional-
ly Short-Cir-
cuit Proof
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:
• A ground fault or short-circuit frequently occurring at the output, can lead to damage to
the unit.
Cyclic Turn
On and
Turn Off
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. Switching
off during the initialization phase can cause undetermined conditions.
GFI
(Ground
Fault
Interrupt
Circuit-
Breaker)
If personnel protection of the system against ground fault 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 (use
privileged) or RCD’s type B (all-current sensitive GFI’s)
The tripping current should be 300mA or more, in order to avoid a premature triggering by
leakage 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 requirements must be observed.
Dependent on the available supply type (TN, IT, TT) further protective measures are necessary
in accordance with VDE Part 410 4( Part 4; Chapter 41).
For example, with TN-mains this protection is made with over current 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 converter!
US - 12
2. Safety Instructions

2.4 EMC instructions
The COMBIVERT R6-S represents electrical equipment designed for use in industrial and commercial installations.
In accordance with the EMC directive 89/336/EEC, it is not mandatory to mark these devices as they represent
components to be further handled by the respective machine and system manufacturer and are not operable
independently according to the EMC directive. The person installing / operating the machine / system 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 as specied by KEB, and when
observing the following measures and installation guidelines.
2.5 EMC conforming installation
The COMBIVERT R6 is designed to be used in a second environment as dened in EN 61800-3 (unit with its own
supply transformer). Take additional measures when using it in the rst environment (residential and commercial
area connected to public low-voltage line)!
• Install the control cabinet or system in an appropriate and correct manner (see chapter “control cabinet
installation”)
• To avoid coupled noise, separate during installation high voltage supply lines, motor lines, control and data
lines (low-voltage level < 48V) and leave a space of at least 6.0 inches, 15 cm between them.
• In order to maintain low-resistance high frequency connections, grounding and shielding, as well as other
metallic connections (e.g. mounting plate, installed units), must be made with bare metal to metal contact with
the mounting plate, over as large a surface area as possible. Use ground conductors with a section as large
as possible, minimum #4 AWG (16mm2) or use thick ground straps.
• Only use shielded cable with copper or tin-plated braid, since steel braid is not suitable for high frequency
ranges. The shield must always be connected to the ground bare on the unit or fastened with clamps to the
bare metal of the sub mounting plate. Do not connect the shield using the drain wires alone, this reduces the
effectiveness of the shield by 70%!
• If external interference suppression lters are used, then these must be installed as close as possible <12
inches (30 cm) to the interference source and must be in metal to metal contact with the sub mounting plate,
over as large a surface area as possible.
• Always equip inductive control elements, (contactors, relays etc.), with suppressors such as varistors, RC-
elements or diodes.
All connections must be kept as short as possible and as close as possible to the ground plane. Free oating
cables act as active and passive antenna.
• Keep connection cables straight (do not loop). Tie all spare unassigned wires at one end to the ground.
• The twisted pair cables should be used when the conductors are not shielded in order to dampen common-
mode noise.
• The cable for phase synchronization between the commutation choke and COMBIVERT R6-S may not exceed
a line length of 39 inches (1 m) .
• Further information can be found on the internet, see “www.kebamerica.com”.

5) Connection to IT and delta power systems after consultation KEB.
Voltage stabilization must be activated at the inverter if a harmonic lter is used. If a harmonic lter is used, volt-
age stabilization must be activated for the inverter which is connected to the DC circuit.
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.

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