  • Page 11: Safety Instructions

    COMBIVERT R6 power supply and regenerative units contain dangerous voltages which can cause death or serious injury. COMBIVERT R6 can be adjusted by way that energy is regenerated into the supply system in case of power failure at regenerative operation. Therefore a dangerous high tension can exist in the unit after switching off the supply system.

  • Page 12: Transport, Storage And Installation

    Warning Protect Against Accidental Contact The COMBIVERT R6 must be protected against invalid loading. Components and covers must not be bent or moved as this may affect insulation distances. The units contain electro- static sensitive devices which can be destroyed by inappropriate handling. For that reason the contact of electronic devices and contacts is to be avoided.
  • Page 13 This is permissible in compliance with the standard, since all inverters are given a high voltage test in the end control at KEB. In the case of special requirements please contact KEB.
  • Page 14 Safety Instructions Caution Prevent malfunctions A trouble-free and safe operation of the COMBIVERT R6 is only guaranteed when the con- nection instructions below are strictly followed. Incorrect operation or damage may result from incorrect installation: • Pay attention to mains voltage.
  • Page 15 Attention Cyclic activation and deactivation With applications requiring the COMBIVERT R6 to be switched on and off cyclically, main- tain 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 undefined conditions. Attention RCD (residual current operated circuit-breaker) When using systems with RCD, the instructions or the requirements of VDE 0100 -T 530 (IEC 60364-5) must be observed.

  • Page 16: Emc Instructions

    EMC instructions EMC instructions COMBIVERT R6-N represent electrical equipment designed for use in industrial and com- mercial units. In accordance with the EMC directive 2006/108/EC, it is not obligatory to mark these devices as they represent components to be further processed by the respective ma- chine and unit manufacturer and are not operable independently according to the EMC di- rective.
