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 defined time in case of return of power supply. -
Page 9: Safety Instructions
Safety Instructions Safety Instructions General instructions 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. -
Page 10: Electrical Connection
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 Insulation the standard, since all units are given a high voltage test during the quality testing at KEB Measurement in accordance with EN 50178. - Page 11 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.
- Page 12 Proof 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 Cyclic Turn off during the initialization phase can cause undetermined conditions.
- Page 13 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.

Page 19: Ferrite Rings
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. -
