  2. External DC supply with current limitation External DC supply without current limitation Thyristors Charging resistor Range over ATV71HD18N4 Range over ATV71HD15M3 Range from ATV71H075M3 up to H015M3X Range from ATV71H075N4 up to HD18N4 II. An external DC supply feeds the ATV71 NO EXTERNAL PRECHARGE CIRCUIT DC supply

  3. External DC supply without current limitation DC supply Thyristors Range over ATV71HD18N4 Range over ATV71HD15M3 R2 drives KM1 II. An external DC supply feeds the ATV71 EXTERNAL PRECHARGE CIRCUIT MANDATORY

  4. II. An external DC supply feeds the ATV71 Use of an external pre-charge device? • The output relay R2 can drive the KM1 contactor. In this case, set DCO to r2

  5. II. An external DC supply feeds the ATV71 • Choice of the precharging contactor

  6. II. An external DC supply feeds the ATV71 • Sizing of the external DC supply • This DC supply: • must be protected against short circuit. • must be able to give the sum of all DC drive current running simultaneously. • must deliver a stable DC voltage

  7. DC supply DC supply II. An external DC supply feeds the ATV71 • Desable the input phase loss • The input phase loss of the ATV71 must be disable. • Short circuit protection (on DC bus and phase to earth) The first aim of this protection is to protect other drives and the DC bus cables Each drive has to be connected to the DC common link by 2 fuses. These fuses must have the capability to clear a DC current.
