1.5 Specified 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 products. If the product is used in machines, which work under exceptional conditions or if essential functions, lifesupporting measures or an extraordinary safety step must be fulfilled, 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 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).

Introduction
1.5.2 Abnormal operation
When exceeding the permissible limit values for voltage, current or temperature the current flow 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 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.

2. Safety Instructions
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 qualified electropersonnel
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 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 field 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 final 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.

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.
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.

Stationary connection
Insulation
Measurement
The COMBIVERT 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 (16mm 2 ) copper conductor or a second ground conductor in compliance with EN 61800-5-1. Ground pointto-point with the shortest connection possible to the main ground point in the system (avoid ground loops).
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.
2. 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 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 finish 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 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 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
Conditionally Short-Circuit 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 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!
US - 12
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 filters as specified 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 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 (16mm 2 ) 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, RCelements 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 commonmode 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”.

The values in brackets must be observed when UL approval is required!
Lay two connection cables parallel at supply and regenerative current > 230 A DC.
The overload current is specified for 1 minute. The overload cycle is 300 seconds. This corresponds to duty class 2
EN 2-60146-1.
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.
Please contact KEB for higher values.

3. Technical Data
5) Connection to IT and delta power systems after consultation KEB.
Voltage stabilization must be activated at the inverter if a harmonic filter is used. If a harmonic filter 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.
The load must be disconnected in case of overcurrent or overload.
The device must be disconnected from the mains supply if a mains fuse has triggered.

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.

4.3 Connection of the COMBIVERT R6
4.3.1 General description of inverter input terminals
Starting current limiting
When connecting inverters to a DC bus pay attention to the internal wiring of the
DC voltage inputs !
Inverters that directly output the DC link bus to the DC terminals must be integrated into the DC bus in a way that the supply unit(s) limit the starting current.
The precharging must be completed within ten seconds.
Maximum DC link capacity
The maximum DC link capacity can be calculated by adding the DC link capacities of all inverters in the DC bus. The supply source (supply unit or inverter with
AC input) must be suitable for this value.
Terminals Description of terminals at KEB inverters

4.3.2 Connection terminals of the power circuit
All terminal strips meet the requirements on EN 60947-7-1 (IEC 60947-7-1)
View of power supply and regenerative units
The terminals of a power supply and regenerative unit can be input or output dependent on the actual operating status (power supply or regeneration). For standardization, the line side is always regarded as input and the DC voltage side is always regarded as output.

4.4.4 Brief Description of the Pre-Charging Sequence
There are three switches coming from the external controller.
S1 engages the contactor K0, which sub-sequentially engages contactor K2 for system precharging. This should be activated first.
S2 enables the R6 unit given that K0 is already engaged.
S3 enables the F5 drive given that there is not fault on the R6 unit.
Sequence of events:
1. S1 switch is closed by the external controller, closing the K0 contactor.
2. K0 13-14 (NO) closes, sending the control voltage (120VAC) to X1B.14 and through
K1 21-22 (NC) to the K2 pre-charging contactor coil. Also K0 23-24 (NO) closes, allowing S2 to enable the R6 unit when switched by the external controller.
3. K2 pre-charging contactor closes, allowing L1 and L2 to connect with pre-charging terminals X1C L1 and L2.
4. Once pre-charging is complete, X1B.13 activates contactor K1. K1 closes, allowing
L1, L2, and L3 to connect with the main power terminals on the R6 and the auxiliary contact K1 21-22 opens, opening K2 pre-charging contactor so the pre-charging is disconnected.

In order to prevent a malfunction caused by interference voltage supply on the control inputs, the following directions should be observed:
EMC
• Use shielded/drilled cables
• Lay shield on one side of the inverter onto earth potential
• Lay control and power cable separately (about 10...20 cm apart); lay crossings in a right angle

5. Operation of the Unit
5.1 Operation with PC and system software COMBIVIS 6
Instructions for the installation and operation of the system software COMBIVIS can be taken from the appropriate software instruction. See kebblog.com/elevator-support for videos.
5.2 Switch-on procedure
The COMBIVERT R6-S is initialized after connection of the power supply. The power circuit identification is checked first. If an invalid power unit is recognized, error „E.Puci” (Power unit code invalid) is released and displayed in the operator. This error cannot be reset, the power circuit must be checked.
The COMBIVERT R6-S changes into synchronization phase if a valid power circuit is recognized. The following procedures happen one after another during this synchronization phase:
• Inspection of correct synchronization connection (error "E.nEt" is triggered, if the synchro nous signal is missing)
• Inspection of the phase allocation of synchronous signals to the mains phases. Error
"E.SYn" is triggered if a phase is missing or in case of phase allocation failure.
The actual line frequency and the mains voltage is determined after successful synchronization. The correct connection of the COMBIVERT R6-S is now ensured. If the control release
(terminal ST) is set, the COMBIVERT R6-S starts independently with the normal operation.
Depending whether regenerative requirement is available, the COMBIVERT R6-S is in status
„rEGEn” or „Stb”.
Status „Stb“
COMBIVERT R6-S detects a typical voltage level in the DC link circuit of the connected frequency inverter (motor operation) and keeps the modulation signals of the regenerative unit deactivated.
Status „rEGEn”
If the DC voltage in the DC link (CP.09 or ru.19) exceeds the value of the regeneration level referring to the reference value ru.18, the modulation signals are activated and the unit changes into regenerative operation. Furthermore the regenerative unit is switched active, if regenerative operation is requested by an additional installed COMBIVERT R6-S in the system (master/slave operation).

Frequently asked questions
The COMBIVERT R6-S is used for supplying frequency inverters with DC input and/or regeneration of excess energy into the supply system.
As a supply unit it converts three-phase input voltage into DC voltage and can be connected in parallel. As a regeneration unit it returns excess energy from generating operation to the utility 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.
