Introduction Preface First we would like to welcome you as a customer of KEB and congratulate you on the purchase of this product. You have decided on a product of the highest technical innovation. The enclosed documents as well as the specifi ed hardware and software are developments of KEB. KEB has created these documents, hardware, and software and they are, to the best of KEB's knowledge, error free.
Preface Specifi ed application The COMBIVERT R6-S 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.
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.
620, the power semiconductor of the unit and existing radio interference fi 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 Insulation accordance with EN 50178.

Proof (Regen) 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. Cyclic Turn On and Turn Off If personnel protection of the system against ground fault is required, the COMBIVERT R6-S must be protected according to EN 61800-5-1: •...
EMC directive are complied with. The prescribed ratings can usually be complied with when using the radio interference voltage fi lters as specifi ed by KEB, and when observing the following measures and installation guidelines.

Troubleshooting and Diagnostics Fault Cause Solution E.OC Ground fault or short Check for any loose or missing power connections. Check for similar errors on the (F5) Elevator Drive indicating a ground fault, short, or excessive current. This may indicate the cause of the fault is occurring from the end of to the drive, motor contactor, or motor.
