1.2 Product description
This instruction manual describes the power supply and recovery unit KEB R6-N. The R6-N has the following
technical features.
As a supply unit
• converts a three-phase input voltage into DC voltage.
• supplies a single KEB frequency inverter or multiple units via DC interconnection.
• can be connected in parallel, if higher supply power is required.
• increases the stability of the DC Bus voltage in shared DC Bus applications.
As a regeneration unit
• returns the excess energy from generating operation (i.e. overhauling load) to the utility supply system.
• reduces the net energy demand.
• reduces the heat dissipation.
• is environmentally friendly.
• replaces braking resistor and braking transistor.
• is cost saving and space saving.
The R6-N is generally protected against over current, ground fault and high temperature.Appropriately dimensioned
DC fuses protect the DC Bus circuit against short-circuit. The following accessories are necessary for operation
with the R6-N:
• Commutation Choke
• HF filter (for observance of European EMC standard)

US - 5
Preface
1.3 Specified application
The R6-N serves exclusively for the supply of frequency inverters with DC input and/or regeneration of excess
energy into the line supply system. The operation of other electrical loads is prohibited and can lead to malfunctions
or destruction of the unit.
1.3.1 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 flow period corresponds to the line frequency and the normal
conduction times of a standard 6 pulse bridge rectifier circuit. Regeneration stops if the DC bus voltage decreases
below the line supply peak voltage (positive power).
1.3.2 Abnormal operation
When exceeding the permissible limit values for voltage, current, or temperature the current flow between DC link
and the line is blocked during regeneration. An appropriate error message is also displayed. When acting as a
supply, the unit must be disconnected from the supply system in case of over current, as current flow can not be
limited by the unit itself in when in this mode of operation.
With factory settings, the modulation is switched off in case of a line phase loss 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 defined time in case of return of power supply.

Safety Instructions
2. Safety Instructions
2.1 General instructions
CAUTION - Risk
of Electrical
Shock
The R6 power supply and recovery unit contains dangerous voltages which can cause death
or serious injury.
The 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 (50VDC) and the AC line voltage at the R6 unit.
Care should be taken to ensure correct and safe operation and to minimise risk to personnel
and equipment.
Only Qualified
Electrical
Personnel
All work from the transport, to installation and start-up as well as maintenance may only be
done by qualified personnel (IEC 364 and/or CENELEC HD 384 and IEC-Report 664 and
note national safety regulations). According to this manual qualified personnel means those
who are able to recognise 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 field of power transmission or conversion.
Observe
Standards
The 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 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 R6 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 final packing, the
R6 must be mounted on a stable mounting base.
Protect Against
Accidental
Contact
The 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.

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 R6 is only permissible on symmetrical networks with a maximum line
voltage (L1, L2, L3) with respect to ground (N/GND) of 317V. An isolating transformer must
be used for networks which exceed this value ! The unit may be damaged if this is not
observed.
Mains Voltage
Tolerance
The incoming mains voltage must remain constant with a tolerance of +/- 10% of the incoming
voltage.
Grounded Delta
Supply
Connection of the R6 series inverters to voltage systems configured 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
Only Fixed
Connection
The R6 is designed for fixed connection only as high frequency ground leakage currents
of > 3.5 mA may occur especially when using EMI filters. 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 filters 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.

Safety Instructions
Different
Ground
Potentials
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 defined 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 defined 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 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 R6-N 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 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 finish where necessary.
• Ground the cabinet or the system with the shortest connection to the main ground point
(avoid ground loops)
• Use exclusively the regen choke or harmonic filter specified 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 R6, the maximum permissible DC
bus capacities of all connected frequency inverters must be considered during supply
operation (see technical data).
• Aferrite ring must be installed over both + and - DC bus connections to the R6 unit
to limit common mode noise on the DC bus.
Automatic
Restart
The 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 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 - 9
Safety Instructions
Conditionally
Short-Circuit
Proof
(Regen)
The 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 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.
GFI (Ground
Fault Interrupt
Circuit-Breaker)
If personnel protection of the system against ground fault is required, the R6-N must be
protected according to EN 61800-5-1:
• 3-phase inverters (with B6 bridge-connected rectifier) 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 filter, 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!

EMC instructions
2.4 EMC instructions
The R6-N 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 filters as specified by KEB, and when observing the
following measures and installation guidelines.
2.5 EMC conforming installation
The R6 is designed to be used in a second environment as defined in EN 61800-3 (unit with its own supply
transformer). Take additional measures when using it in the first 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 filters 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 floating
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.
• Further information can be found on the internet, see "www.kebamerica.com".

Storage
2.6 Storage of the Unit
The DC bus of the KEB R6 is equipped with electrolytic capacitors. If the electrolytic capacitors
are stored de-energized, the oxide lm working as dielectric uid reacts with the acidic electrolyte
and destroys itself slowly. This affects the dielectric strength and capacity of the unit. If the
capacitors start running with rated voltage again, the oxide lm tries to build up quickly. This
causes heat and gas and leads to the destruction of the capacitors.
In order to avoid failures, the KEB R6 must be started up according to the following specication
based on duration of storage period (powered off):
Storage Period < 1 Year
*Start up normally, without any additional precautions
Storage Period 1...2 Years
*Power on frequency inverter for one hour without modulation
Storage Period 2...3 Years
*Remove all cables from power circuit
*Open control release
*Connect variable voltage supply to inverter input
*Increase voltage slowly to indicated input level and remain at for the specied time.
Voltage Class Input Voltage Minimum Time
230V 0...160V 15 min
160...220V 15 min
220...260V 1 h
460V 0...280V 15 min
280...400V 15 min
400...500V 1 h
Storage Period > 3 Years
*Input voltages same as above, however double the amount of time for each additional year.
Eventually consider changing capacitors.

1) The supply voltage must be a center grounded wye connection with +/-10% mains voltage tolerance
2) The over load time is specified for 1 minute. The overload period is 300 seconds. This corresponds to duty class 2 EN60146-1-1.
3) The current ratings are based on a displacement power factor of g=0.95. The displacement power factor or the effective value of the input current
is dependent on load and line supply conditions. With uncontrolled diode bridge rectifiers, the power factor can be set to 1.0, so the value of the
fundamental frequency components is equal to the value of the displacement power factor.
4) For installations according to the UL 508C standard and DC supply currents > 85A, the DC bus connection must use both ++ and -- terminals with
a second parallel conductor.
5) The wire gauge is based on the maximum fuse rating, copper wire with a 75°C insulation rating, THHW or equivalent. If branch circuit protection is
selected based on the continuous current below the rated value, the wire size could be reduced.
6) For installations with isolation transformers, follow fuse sizing guidelines of NEC NFPA-70. Fuse size may be lower than the fuse rating of the unit.
The fusing of the transformer supercedes the fuse rating of the unit. See page 8 for further details.
The units are not short circuit proof without correctly dimensioned fuses
Exceeding the maximum DC bus capacitance can lead to failure.
A load disconnection in the DC bus circuit may only occur after the operating status „Standby" is achieved.

3.5.5 Ferrite Rings
Ferrite rings are required to minimize electrical disturbances on the DC bus connections between the inverter(s)
and the COMBIVERT R6 unit. The ferrite rings are to be installed over both the ++ and -- DC bus conductors. Do
not use ferrite rings intended for the inverter(s)' motor leads on the DC bus as doing so negates the effect. Do not
pass ground conductors through the ferrite rings. The ferrite rings are selected based on the size of the conductor
and the inner diameter of the ring.

4.4.1 Points for General Consideration
Always use UL listed and CSA approved wire. Use 60/75°C copper conductors only. Use
minimum 300V rated wire with 230V systems and minimum 600V rated wire with 480V systems.
Suitable for use on a circuit capable of delivering not more than 10000 rms symmetrical
amperes, 240 or 480 volts maximum when protected by fuses as listed in table 3.1.

1) KEB recommends using fast acting class J fuses only (ex. Bussman type JKS). For applications with KEB Harmonic Filters and an isolation
transformer, a high speed class J fuse must be used (only Ferraz type HSJ is approved).
2) Harmonic filters must have the manual motor starter (MMS) turned on to include the capacitor assembly in the circuit. See section 4.4.9 for
more details

1) KEB recommends using fast acting class J fuses only (ex. Bussman type JKS). For applications with KEB Harmonic Filters and an isolation
transformer, a high speed class J fuse must be used (only Ferraz type HSJ is approved).
2) If the inverter current is greater than the current of one COMBIVERT R6, the DC bus conductors from the inverter must be connected to an
external terminal block to split the current to multiple R6 units. In this case the conductors to each R6 unit must be at least 6 AWG (10 AWG for
the size 15R6) or larger based on the DC bus current to each unit.
3) Due to tolerances in the inductance values of the commutation choke or harmonic filter, the actual available power of each R6 unit must be
reduced by 15% to account for unequal load sharing. Therefore the total power available is reduced. With parallel connection of different sized
R6 units, it is necessary to use the same commutation choke or harmonic filter in order to maintain the same short circuit voltage (uK) across
the chokes.
4) For parallel applications, a synch cable(s) must be used for a daisy chain connection to all units. These connections are only needed for parallel
units and not used for single units.
Sizings with harmonic filters must utilize Wiring Scheme A (Sections 4.4.2 and 4.4.3) and
should only be used in combination with harmonic filters from KEB.
